MIX 56

Telect’s Multiplexer with Integrated Cross-Connect, 56 Circuit (MIX 56)

chassis houses two fully independent systems, each with 28 DSX jacks and

up to two M13 multiplexer cards. Each system can be used as a DSX only,

as a nonredundant multiplexer, or as a redundant multiplexer.

When used as a DSX only, a system can be cabled quickly using the rear

64-pin connectors and provides full DSX functionality, including patching

and monitoring, using the DSX jacks on the chassis front.

When a single M13 card is added, a system becomes a nonredundant multi-

plexer/demultiplexer, which combines 28 DS1 or 21 E1 signals into a sin-

gle industry standard DS3 signal and separates a DS3 signal into 28 DS1 or

21 E1 signals.

Adding a second card provides 1:1 redundancy for all M13 functionality.

The 28 DS1 low-speed channels and the DS3 high-speed interfaces reside

on one M13 card occupying one card slot, while the protection card occu-

pies the second card slot. The two cards are in constant communication,

and all configuration changes made to the active card are also automatical-

ly made to the standby card.

Redundant and nonredundant multiplexer applications include full DSX

functionality when DS1 wiring is connected to the wire-wrap pins on the

front of the chassis, rather than to the rear 64-pin connectors.

Configuration, diagnostics, and performance monitoring are performed us-

ing SNMP through the Ethernet port, or using the Craft interface either re-

motely with Telnet through the Ethernet port or locally through the RS-232

Craft port.

ALERT! To avoid electrostatic discharge, always

wear a grounding strap plugged into the ESD jack

when handling any MIX 56 components.

Front Panel

Each MIX 56 chassis houses two independent systems, System 1 and Sys-

tem 2. The front of each system is equipped identically (with the exception

of one electrostatic discharge (ESD) jack per chassis), and either system

can be used as a DSX only, as a nonredundant multiplexer, or as a redun-

dant multiplexer.

vent harmful electrostatic discharge to electronic components.

Fanning Strip: One row per wire-wrap pin field. Used to properly dress

cross-connect wires.

M13 Cards: One or two per system. Houses the active circuitry for multi-

plexing functions. One card for nonredundant systems, two cards for re-

dundant systems.

Wire-Wrap Pinfield: 28 DS1 pin fields per system. Used for routing and

cross-connecting DS1 signals. When using as a mux, Telect recommends

using these DS1 wire-wrap connections. This method of connecting the

low speed signals does not provide signal patching capabilities.

NOTE

To use a system as a multiplexer with full DSX capabilities, connect incom-

ing and outgoing DS1 signals to the front wire-wrap pins.

LEDS

The LED status indicators on the MIX 56 front panel are grouped into the

following categories:

•

DSX Tracer Lamps: When the tracer lamp (TL) pins of the cross-con-

nected modules are connected, the lamp lights when a plug is inserted

in the monitor port of one of the modules.

•

M13 Card Status LED: One per card.

◊ Lights green for the active card.

◊ Lights orange for a standby card with no critical alarms.

◊ Solid red on the standby card indicates the card has detected a criti-

cal alarm condition or is otherwise nonoperational.

◊ Flashing red indicates a card cannot resolve an alarm condition.

◊ Unlit means the card is not receiving power, or has a failure in the

processor circuitry.

Cabling a System

The MIX 56 chassis contains two independent systems that each require

cabling. Telect recommends routing cables to the side of the chassis the

system is on, not crossing the cables to the other side of the chassis.

The following instructions describe cabling one system. To cable the other

system, repeat these steps, but route cables so as to create a mirror effect

from the first system. If using as a DSX only, this requires using 64-pin

connectors on the other system that are the reverse orientation of those

used on the first system.

If you are using the system as a DSX only, route the DS1 signals to the rear

64-pin connectors. This method provides full DSX functionality, including

patching and monitoring, using the DSX jacks on the chassis front.

If you are using the system as a redundant or nonredundant multiplexer,

full DSX functionality is available when you route the DS1 signals through

the wire-wrap pinfields on the front of the chassis, rather than through the

rear 64-pin connectors. You can still use the system as a multiplexer when

DS1 signals are routed through the rear 64-pin connectors, but you will not

have patch-jack functionality.

ed to the front wire-wrap pins, you can perform all DSX functions includ-

ing cross-connecting circuits with other network elements, rerouting traffic

with patch cords, and nonintrusive monitoring signals.

NOTE

If the system is used as a multiplexer, but the DS1 signals are connected to

the rear 64-pin connectors, you cannot reroute traffic with patch cords.

Patching Signals

ALERT

ALERT! When using a MIX 56 system as a multiplexer, you

must route DS1 signals to the front wire-wrap pins to be able to

patch signals.

If you need to perform network maintenance or emergency patch-arounds,

you can reroute incoming and outgoing lines by making temporary connec-

tions using either two single patch cords or a dual patch cord. Patching is

service-affecting, and the circuit is briefly interrupted while setting up and

taking down the patch.

MODEM OPERATION

You can connect a modem to the MIX 56 serial port to control the system

remotely over an analog phone line. To do so, you must set the “Modem

Detect” field on the System Interfaces screen to “Enabled” (Chapter 2) and

install the modem according to the instructions in Chapter 2. When you

have done so, activate the modem by pressing and holding the ACO switch

until all LEDs light (LED test), then release the switch.

If you set Modem Detect to “Enabled,” but you have a PC rather than a mo-

dem connected to the MIX 56 serial port, the modem detect code

“+++ATQ” appears on the screen at the current location of the cursor when

you release the ACO switch. To clear the “+++ATQ,” switch to another

MIX 56 screen.

The modem automatically detects baud rate at the MIX 56 serial port when

the modem is off-line. Once the modem is on-line, it will not change its

baud rate. If you change the MIX 56 baud rate (System Interfaces screen)

while the modem is on-line, you create a baud mismatch between the MIX

56 and modem, which shuts down the connection. The only way to regain

the connection is to “hang up” at the remote modem, press the ACO switch

until the LED test starts, release the switch, and reestablish the link from

the remote end.

To disconnect a modem, see the instructions in Chapter 2.

MANAGING A SYSTEM

You can configure, test, and monitor a system using these interfaces:

•

Via Ethernet Port located on rear of chassis (one per system):

◊ SNMP (Simple Network Management Protocol) Interface

◊ Craft Interface over Telnet connection (up to two Telnet sessions)

◊ TL1 Interface over Telnet connection (up to two Telnet sessions)

Via Craft Port (serial port) on front of chassis (one per system):

•

◊ Craft Interface over RS232 serial connection

◊ TL1 Interface over RS232 serial connection

Via Remote Control:

If the MIX 56 is connected over the DS3 link to another MIX 56 and

they are both in C-bit mode on the DS3 link, then a remote control ses-

sion can be run where the user is controlling the MIX 56 at the remote

end of the DS3 link.

◊ Craft Interface over DS3 Link

◊ TL1 Interface over DS3 Link

ALERT

ALERT! It is possible to have multiple active sessions at the

same time involved in configuring the same system. It is possi-

ble to have five active sessions at the same time: one via the

serial port; two via Telnet connections; one SNMP; and one via

Remote Control.

MIX 56 User Manual

Interfaces

SNMP Interface

Telect provides a private enterprise MIB (management information base)

with which you can perform all MIX 56 functions. Telect’s private enter-

prise MIB also supports many features of the standard RFC 1213 MIB II.

You can download the latest MIB at www.telect.com.

You can use any SNMP-compatible network management system such as

SunConnect’s SunNet Manager, HP Open View, or Castle Rock’s SNMPc

to manage a system.

SNMP is available only over the Ethernet port.

Craft Interface

The Craft interface is a menu-driven system that can be accessed either by

the Craft (serial, RS232) port or Ethernet port. The Craft interface is cov-

ered in detail in this section of this manual.

TL1 Interface

The TL1 interface is a command line system that can be accessed either by

the Craft (serial, RS232) port or the Ethernet port. The TL1 interface is

covered in TL1 Design, Telect document 126055, included with the

MIX 56 System Software.

Ports

Craft Port

The Craft port is a nine-pin (DB9) RS-232 serial port located on the front

of the chassis that connects to an RS-232 terminal or a PC running terminal

emulation software in VT-100 mode. The terminal or PC port must be set

for 8 data bits, 1 stop bit, no parity; and its baud rate must match the Craft

port’s setting of the MIX 56. Craft port baud rate choices are 9600, 19200,

38400, 57600, or 115200. (The baud rate can be set from the Craft inter-

face’s System Interfaces screen or the TL1 command “set-baud”.)

Use a shielded, straight wire RS-232 cable (not null modem cable) with a

male DB9 connector to connect to the Craft port.

Ethernet Port

The Ethernet port is a 10Base-T port that is located on the rear of the chas-

sis. Configure your network port as half duplex to match the MIX 56 Ether-

net port.

MIX 56 User Manual

4 Software Operation

NOTE

Before using the Ethernet port, you must connect over the Craft port and

set the system’s IP, Subnet Mask, and gateway addresses. This can be done

from the Craft interface’s System Interfaces screen or by the TL1 com-

mands “set-ip-addr”, “set-subnet-mask”, and “set-gateway”. Remember

to set the Ethernet port to half-duplex. See “Specifying System Interface

Settings” on page 4-17.

To Connect With a Craft Interface Over the Craft Port

Step Action

If you are connecting to a PC, run terminal emulation software in

VT-100 mode.

Configure the terminal or PC port for 8 data bits, 1 stop bit, and no

parity.

Configure the terminal for the same baud rate as the MIX 56 is set

for in the System Interfaces screen. Choose between 9600 (default),

19200, 38400, 57600, or 115200 baud.

Connect the DB9 male end of the included cable to the DB9 female

port labeled “Craft” of the system (1 or 2) to which you are con-

necting.

Connect the other end of the cable to the RS232 terminal (or a PC

running terminal emulation software in VT-100 mode).

Press Enter.

The Directory screen, the Date and Time screen, or the Log In

screen appears, depending on your security setting and whether the

date and time has been entered since power up.

NOTE

The default security setting is Off.

ACCESSING THE CRAFT INTERFACE

Each MIX 56 chassis houses two independent systems. When you access

the Craft interface, whether through an Ethernet port on the rear or a Craft

port on the front, your actions affect only the system on the same side of

the chassis as the port to which you connected. The system on the other

side is completely unaffected.

Setting Security

You can restrict access to the MIX 56 by setting security to On. When secu-

rity is on, the Log In screen is the first screen that appears when a Craft in-

terface session is initiated. Users must type their user ID and password to

access any other screens and perform any other functions. When security is

set to Off, the Directory screen is the first screen that appears , and all

screens are accessible to anyone.

There are three levels of security a user can be assigned:

•

Admin Rd/Wr where the user has full access to the MIX 56.

Config/Test where the user has access to Screens 6 and 7 to Configure

the DS3 and DS1 lines. The user also has access to Screens 19 and 20

to conduct loopback and BER testing.

•

Read Only where the user can read all screens but has no rights to

change anything.

NOTE

The default user ID is “TELECT” and the default password is “TELECT.”

They are stored in slot 1 of the Security screen upon first power-up and can

be overwritten.

ALERT

ALERT! Do not set the Security field to On without at least one

valid user ID and password in the system. Once security is on,

you cannot access the Craft interface without a user ID and

password. See “Managing Users” on page 4-10.

1. If the date and time have never been entered since power on, then the date and time screen will be the first screen that

appears.

DS1 signal type is T1, one of two types of E1, or mixed T1’s and E1’s.

When you select T1, all 28 channels become T1, and the Line Code choic-

es are limited to AMI or B8ZS. The type of E1 signal you select determines

the configuration:

•

21 channels become E1, channels 22 through 28 become unavailable,

and the Line Code choices are limited to AMI or HDB3;

•

21 channels become E1 with every fourth line unavailable, and the Line

Code choices are limited to AMI or HDB3.

When you select “Mixed, T1’s and E1’s” you can then specify in blocks of

four DS1 lines whether the block is T1’s or E1’s. If a block is selected for

E1, then the fourth line in the block becomes unavailable. Each block of

four lines can be four T1’s or three E1’s.

Tab to the State field, select whether the channel is active or inac-

tive by pressing the spacebar to toggle between “Enabled,” “En-

abled No Alarms,” and “Disabled,” and then press Enter.

NOTE

The “Enabled No Alarms” state means that the DS1 line is active

but not monitored for error conditions. No alarms will be reported.

Tab to the Interface field, select the interface by pressing the space-

bar to toggle between NI (network interface), CI (customer inter-

face), and TI (Telect or Through Interface). Then press Enter.

Changing the interface changes the loop-up and loop-down codes

that get set for recognition on receiving and for transmitting when

requesting a loopback at the other end. The loop-up and loop-down

codes are what the MIX 56 will recognize as codes to go into and

out of loop back on a low speed line.

The TI setting can be thought of as a through interface or pass

through interface for the NI and CI loop back codes. The TI setting

defines loop-up and loop-down codes that are different from the tra-

ditional NI and CI loop codes. This causes the MIX 56 to not rec-

ognize the NI and CI loop codes when the interface is set to TI. By

not recognizing the NI and CI loop codes the MIX 56 just passes

these loop codes through to the next piece of equipment.

The TI interface defines another set of loop-up and loop-down

codes. This means that if two MIX 56’s are connected together and

both are set to the TI interface on a low speed line, then the TI loop-

up and loop-down codes will be recognized between these two

MIX 56’s.

Restoring a Configuration

In the Restore Configuration screen, you can load any saved configuration,

as well as the original Factory configuration. You can also restore the entire

non-volatile ram, (NVRam), from a file.

Restoring with a saved configuration in NVRam or to the Factory configu-

ration resets all the settings in the System Settings screen, High Speed Con-

figuration screen, Low Speed Configuration screen, Alarm Threshold

screen, and Loopbacks screen.

Restoring to the Factory configuration also disables security and resets the

System Interfaces screen. Restoring to the Factory configuration does not

change any of the three NVRam saved configurations.

Restoring the entire NVRam configuration from a file restores all three of

the saved configurations plus restoring all the settings of the Security

screen, Alarm Threshold screen, System Interface screen, and Update

Flash screen.

ALERT

ALERT! Restoring the entire NVRam from a file or restoring to

the Factory configuration resets the System Interfaces screen

which includes the IP address, Subnet Mask address, and the

Craft Port’s baud rate. This has the possibility of killing your

communications link.

The Factory configuration does not have an IP address or Sub-

net Mask address. If you restore this configuration remotely,

you will not be able to reconnect to the system until the ad-

dresses are added through the local Craft Interface via the Craft

port.

The Factory configuration resets the local Craft Port’s baud

rate to 9600.

From the Directory screen, type 4 to select Restore Configuration

and press Enter.

In the Select Number field, type the number of the desired option.

The first three options are the saved configurations in NVRam. Op-

tion 4 is the restore to Factory configuration. Options 5 and 6 re-

stores the entire NVRam’s configurations from a file where option

5 receives the configuration data from the Craft port and option 6

receives the configuration data from the Ethernet port via a TFTP

file transfer.

• If you selected options 1, 2, or 3, then —

A prompt appears asking you to confirm restoring the configu-

ration. Type y and press Enter.

•

If you selected option 4, “Factory”, then —

A prompt appears reminding you that this sets the baud rate to

9600, erases the Ethernet IP address and subnet mask address,

and asks you to confirm restoring to the factory default configu-

ration. Type y and press Enter.

NOTES

If the restored factory configuration has a different baud

rate setting, the Craft Port screen becomes unreadable. To

restore the screen, change the baud rate to 9600.

If the Craft connection is a telnet session this will kill your

session. The factory configuration clears out all the network

addresses on the System Interfaces screen. To restore a tel-

net session the network addresses will have to be setup from

a local craft session via the Craft port.

Restoring to factory defaults reboots the Mix56 card.

MANAGING ALARMS AND EVENTS

When you access the Craft interface, whether through an Ethernet port on

the rear or a Craft port on the front, the information you view and the set-

tings you specify are only for the system on the same side of the chassis as

the port to which you connected. You must connect to the other system to

manage its alarms and events.

When an alarm condition occurs within a system, MIX 56 alerts you in the

following ways:

•

The critical, major, or minor front panel LED lights.

The critical, major, or minor alarm contact on the rear panel activates,

sending the alarm to a separate alarm system.

•

An SNMP trap is sent if the network IP address, Subnet Mask, and a

Trap Address are set from the System Interfaces screen.

An entry detailing the alarm condition is made in the Alarm Log and

the Current Alarms screen.

When the alarm clears, the LED goes out, the alarm contact deactivates, a

second SNMP trap is sent, the alarm is removed from the Current Alarms

screen, and a second entry is made in the Alarm Log detailing the time the

alarm cleared.

MIX 56 defines alarm levels as follows:

Critical: service-affecting conditions that cause the loss of two or more

low speed line or the loss of the high-speed line.

Major: service-affecting conditions that cause the loss of a single low

speed line or cause performance issues on the high-speed line.

Minor: conditions that do not affect service.

You can view the alarms for either the active card or the standby card.

To View Current Alarms

The Current Alarms screen displays the date and time the alarm started, de-

tails about the alarm, the time remaining on the Alarm Cutoff (ACO) timer

(if it has been engaged), and where you can engage and disengage the

ACO. Engaging the ACO closes the external alarm contacts, turning them

off, while disengaging the ACO turns external alarms back on.

Setting Alarm Thresholds

In the Alarm Thresholds screen, you can specify some of the conditions

that trigger and clear the system alarms. Each threshold is counted in one

second increments, and for most alarms, you can set one threshold to trig-

ger the alarm and another to clear it (ES and SES alarms do not need Alarm

Off thresholds because they clear automatically when the time span on

which they are based passes).

For example: to set an alarm to trigger when the High Speed circuit experi-

ences more than 3 seconds of Loss of Signal (LOS), set the Alarm On

threshold to 003. Then set the Alarm Off threshold to the amount of time

the condition must be absent before the alarm clears (ex. 010 = 10 seconds

of no LOS).

You can set thresholds for the following alarm conditions for both the high-

speed and the low-speed signals:

Alarm Indication Signal (AIS). AIS indicates more serious impairments,

such as upstream failures. The system is receiving AIS, a signal sent to in-

dicate a transmission interruption located either at or downstream from the

equipment sending the AIS. DS3 AIS is a framed signal containing alter-

nating ones and zeros, whereas DS1 AIS is an unframed all-ones signal.

Loss of Signal (LOS). The absence of any detectable transmission pulses.

Errored Seconds-15 minutes. The number of errored seconds (ES) in a

15-minute span. An errored second is a second in which Loss of Signal or

at least one Coding Violation (CV) occurs.

Errored Seconds-24 hours. The number of ES in a 24-hour span.

Severely Errored Seconds-15 minutes. The number of severely errored

seconds (SES) in a 15-minute span. A severely errored second is a second

in which 320 or more CV occur.

Severely Errored Seconds-24 hours. The number of SES in a 24-hour

span.

Additionally, you can set thresholds for the following alarm conditions for

the High Speed signal only:

Remote Alarm Indication (RAI). The system is receiving RAI, a signal

sent to indicate the far-end equipment is not receiving a DS3 signal from

the MIX 56.

Out of Frame (OOF). The signal does not meet the framing requirements

of the Framing Mode (C-bit or M13) specified in the High Speed Configu-

ration screen.

The Alarm Thresholds screen also displays the status of the system’s re-

dundancy switching capabilities. Locked means the system has automati-

cally switched due to some error and the system is locked from automati-

cally switching again. The system is locked for 10 minutes after any

automatic switch or for 12 hours after the third automatic switch within a

one hour time frame. You can enable switching again by tabbing to the

[Clear Lock] button and pressing Enter.

Running Loopbacks

ALERT

ALERT! When a loopback is running, the low-speed channel or

high-speed circuit on which it is running is out of service.

The following loopbacks can be set from the Loopbacks screen:

Low Speed “Line”: The signal is sent through the DS1 LIU (Line Inter-

face Unit) and looped back before reaching the Encoder/Decoder. The DS1

Received signal is looped back out as the DS1 Transmitted signal.

Low Speed “Local”: The demultiplexed DS1 signal from the M13 MUX

is encoded and sent to the DS1 LIU Equalizer, where it is looped back

through the DS1 LIU Decoder, and then multiplexed and added to the DS3

stream by the M13 MUX.

High Speed “Line DS3”: The received signal is sent through the DS3 LIU

and through the M13 MUX Decoder, where it is looped back through the

Encoder and put onto the DS3 stream. The DS3 Received signal is looped

back out as the DS3 Transmitted signal.

High Speed “Local DS3”: The signal is sent through the DS1 LIUs, multi-

plexed, and looped back before reaching the M13 MUX Encoder.

High Speed “Line, DS1 Ch xx in DS3”: The signal path is the same as the

“Line, DS3” loopback, but instead of the entire DS3 signal being looped

back, an individual DS1 channel of the Muxed DS3 signal is looped back.

The illustration below shows the path of each loopback.

The following remote loopbacks can be requested from the Loopbacks

screen:

Low Speed “Remote Tx LpUp”: Transmits a DS1 Loop Up code for 6

seconds. The MIX 56 uses CSU loop codes.

Low Speed “Remote Tx LpDn”: Transmits a DS1 Loop Down code for 6

seconds. The MIX 56 uses CSU loop codes.

High Speed “Remote DS1 Ch xx in DS3”: Requests a loopback of the in-

dividual DS1 signal for Channel xx of the MUXed DS3 signal at the other

end of the DS3 link.

High Speed “Remote All DS1’s in DS3”: Requests a loopback of all DS1

signals of the MUXed DS3 signal at the other end of the DS3 link. This re-

mote loopback request is only available if the DS3 mode is set for C-Bit.

High Speed “Remote DS3 (Line)”: Requests a loopback of the entire

DS3 signal at the other end of the DS3 link. This remote loopback request

is only available if the DS3 mode is set for C-Bit.

NOTES

•

The MIX 56 will respond to receiving low-speed and high-speed remote

loopback requests if the “Loopback Permission” is set to Yes on the

System Settings screen.

Low-Speed Loop-Up and Loop-Down codes vary depending on the in-

terface setting and whether they are transmitted or received. The inter-

face setting for the individual DS1 line is set from the Low Speed Con-

figuration Screen.

The Loop-Up and Loop-Down codes and the number of bits in each

code are CSU loop codes, as defined below:

Settings screen is set to Yes. If loop back permission is set to Yes then

the MIX 56 will —

◊ Go into loopback when the loop-up code is no longer received and

it had received the loop-up code for at least 5 seconds. A loopback

is not established until the loop-up code is no longer received after

being received for at least 5 seconds.

◊ Go out of loopback when the loop-down code has been received for

5 seconds. A loopback is cancelled after receiving the loop-down

code for 5 seconds, it does not wait for the loop-down code to cease

being received.

•

The low-speed loop-up and loop-down codes can be received and

transmitted either via the individual DS1 channel of the MUXed DS3

signal or via the corresponding DS1 line. The MIX 56 can be set up to

either the DS3 or DS1 direction but not both at the same time. The low-

speed remote loopback direction, DS3 or DS1, is set by the “LS Remote

LB Dir” field of the System Settings screen.

◊ “LS Remote LB Dir” set for DS3 (default): The loop-up and

loop-down codes are received and transmitted on the corresponding

DS1 channel of the MUXed DS3 signal. The loopback set on re-

ceiving the loop-up code is the low-speed local loopback. A loop-

up or loop-down code received on the DS1 line is not recognized.

◊ “LS Remote LB Dir” set for DS1: The loop-up and loop-down

codes are received and transmitted on the corresponding DS1 line.

The loopback set on receiving the loop-up code is the low-speed

line loopback. A loop-up or loop-down code received from the cor-

responding DS1 channel of the DS3 signal is not recognized.

Using a 3/16 nut driver or a wrench, remove the two Craft port hex

nuts shown below.

Using pliers, grasp the alarm card by the Craft port and pull the card

Replace the hex nuts and tighten them until the alarm card is se-

curely in place.

Replace the LED panel faceplate by inserting the pin in the mount-

ing hole, inserting the captive screw into its slot so that the face-

plate is flush with the chassis, and tightening the screw.

UPDATING THE SOFTWARE

The method you use to update a system’s software depends on the configu-

ration of the system. Redundant systems are updated using Trivial File

Transfer Protocol (TFTP) through the Ethernet port or directly through the

Craft port. Redundant systems can also be updated automatically by

switching between standby and active cards or by manually transferring the

program. Nonredundant systems are updated directly through the Craft

port.

Regardless of which method you use, you must first download the update

from Telect’s website and ensure the files can be accessed by the system

during the update process.

Warning — Do not use HyperTerminal to download upgrades through the

serial port to the MIX 56. Data might be lost while using HyperTerminal to

download the new upgrade. Telect would recommend the use of other ter-

minal programs such as ProComm for doing Serial upgrades. Telect Inc.

uses ProComm (copyrighted by Symantec Corporation) for doing serial

updates.

Warning — Telect recommends that all updates/upgrades be performed in a

maintenance window, and that all configurations be copied prior to per-

forming any updates/upgrades. Performing updates/upgrades on non-re-

dundant M13 single-card systems will cause loss of system configurations,

requiring configuration information to be re-entered after any such update/

upgrade. In addition, performing updates/upgrades on a redundant system

may cause loss of system configurations. If you have any questions, please

contact application engineering before starting any software updates/up-

grades.

TFTP Update

Before beginning, ensure the two update files are on a TFTP server accessi-

ble to the MIX 56 system. You must also know the base name of the update

files and the network address of the TFTP server on which it resides.

NOTE

The TFTP update can only be done on a redundant system. You may want

to Ping the TFTP server to ensure it is up and running. See “To Ping Other

Systems on the Network” on page 4-19.

Transferring Software Versions Between Cards

This pertains to redundant systems where the standby card has a newer ver-

sion of software, but the customer prefers the older version currently on the

active card. This procedure allows the customer to transfer the older ver-

sion onto the standby and eliminate version mismatch.
