REQUIREMENTS/SP ECIF ICATIONS  
CHAP TER 2  
REQUIREMENTS/SP ECIF ICATIONS  
This chapter describes cable requirements, power requirements, and  
operating specifications for the TRXI. Be sure that you read this  
chapter before you install the TRXI. Your network must meet the  
requirements and conditions specified in this chapter to obtain  
satisfactory performance from this equipment. Failure to follow these  
guidelines could result in poor network performance.  
2.1 CABLE SP ECIF ICATIONS  
The basic concept of a token ring is a set of Trunk Coupling Units  
(TCUs) connected by trunk cabling. You can extend the trunk cabling  
by installing TPIMs into the TRXIs RI/RO ports. TPIMs have  
embedded repeaters and provide trunk connections for UTP, STP,  
Multimode Fiber, and Single Mode Fiber cabling.  
You attach stations to the TCU lobe ports with lobe cabling. Figure 2-1  
shows the various ports and cables.

REQUIREMENTS/SP ECIF ICATIONS  
2.1.1 UTP Ca ble Sp ecifica tion s for th e TRXI-22/24 Lobe Por ts  
a n d TP IM-T2  
The TRXI-22 and TRXI-24 lobe ports and the TPIM-T2 support voice  
grade Unshielded Twisted Pair (UTP) cable, as described in EIA/TIA  
TSB 568, and IBM Type 3 cable.  
UTP consists of four pairs of 24 AWG solid wire for data or voice  
communication and is typically used to wire cable runs within the  
walls of buildings. In some installations, existing UTP building wiring  
can be used for token ring cabling. UTP cable must conform to the  
limits shown in Table 2-1.  
Wa r n in g: DO NOT connect UTP cabling to any non-token ring network  
conductors (telephone, etc.) or ground. If in doubt, test wiring before  
using. Telephone Battery and Ringing voltages, used in UTP telephone  
circuits, could present a shock hazard and can damage token ring  
equipment when connected to token ring cabling.  
The increased popularity and cost advantages of UTP cable have  
driven refinements to UTP cable design. As a result, better grades of  
UTP cable, known as supergrade or level 4, are available that exhibit  
improved transmission characteristics. These improved grades of UTP  
can often be used to permit operation at 16 Mbps on longer lobe cables.  
Atten u a tion a n d Im p ed a n ce  
The values listed in Table 2-1 include the maximum attenuation of the  
cables, connectors, patch panels, and reflection losses due to  
impedance mismatches in the segment.

Used for the longest cable runs within the walls of buildings.  
IBM Typ e 2 - Similar to Type 1 data cable, but having four  
additional UTP lengths of 22 AWG solid wire carried outside of  
the shield casing. Typically used for voice communication and  
often used to wire cable runs within the walls of buildings.  
IBM Typ e 6 - Two STP lengths of 26 AWG stranded wire for  
data. This type is used in patch panels or to connect devices  
to/from wall jacks. Attenuation for Type 6 cable is 3/2 x Type 1  
cable (66 m of Type 6 =100 meters of Type 1).  
IBM Typ e 9 - Similar to Type 1, but uses 26 AWG solid wire.  
Attenuation for Type 9 cable is 3/2 x Type 1 cable  
(66 m of Type 9 = 100 meters of Type 1).

2.1.3 Mixed Ca ble Typ es  
If you mix cable types in your installation, you must compensate for  
the different cable attenuations. Type 6 and Type 9 cables can be run  
for only 2/3 the distance of Type 1. This means:  
10 meters (Type 1) 6.6 meters (Types 6, 9)

2.2 CABLE RECOMMENDATIONS/TROUBLESHOOTING  
The following sections describe common cable problems and  
recommendations for correcting them.  
Cr ossta lk  
Crosstalk is interference caused by signal coupling between the  
different cable pairs contained within a multi-pair cable bundle.  
Multi-pair cables should not be used for UTP lobe cabling. UTP lobe  
cabling should be dedicated to carrying token ring traffic. Avoid  
mixing token ring signals with other applications (voice, etc.) within  
the same cable.  
Noise  
Noise can be caused by either crosstalk or externally induced  
impulses. If noise induced errors are suspected, it may be necessary to  
reroute cabling away from potential noise sources (motors, switching  
equipment, fluorescent lighting, high amperage equipment), or to  
ensure that the electrical wiring in the area is properly wired and  
grounded.  
Tem p er a tu r e  
The attenuation of PVC insulated cable varies significantly with  
temperature. Plenum-rated cables are strongly recommended at  
temperatures greater than 40˚C to ensure that cable attenuation  
remains within specification. Check the cable manufacturers  
specifications.  
In addition to complying with the preceding cable specifications, the  
following recommendations should be followed to minimize errors and  
help to obtain optimum performance from your network:  
UTP cabling should be free of splices, stubs or bridged taps.  
No more than two punch-down blocks between TCU ports and  
wall outlets.  
Metal troughs, ducts, etc. carrying token ring signals should be  
properly grounded.  
Page 2-9  
Download from Www.Somanuals.com. All Manuals Search And Download.  
REQUIREMENTS/SP ECIF ICATIONS  
Token ring signals should not be routed through copper cables  
that exit a building or which are adjacent to cables either  
exiting a building or exposed to lightning strikes and power  
surges.  
UTP cables that contain token ring signals should not be  
simultaneously used for applications which may impress high  
voltages (greater that 5 volts) with sharp rise or fall times,  
since the noise coupling from such signals could directly cause  
errors on the token ring network.  
For single telecommunications closet rings, lobe lengths should  
not exceed 100 meters or 22 to 24 AWG wire from the attaching  
device and the TCU port.  
When possible, use dedicated UTP cable for token ring signals.

3. You will need a pencil for this step. With the wall mounting  
brackets attached to the TRXI, position the TRXI against the wall  
where it will be permanently mounted with the network port facing  
down. Using a pencil, mark the wall location for the four pilot holes.  
4. Set the TRXI aside and carefully drill four 1/4" pilot holes, one for  
each of the Molly screw anchors and insert the four Molly screw  
anchors into the holes just drilled.  
5. Tighten each of the anchor screws until the anchor expands holding  
the anchor firmly in the wall, then remove the screws completely.  
6. Position the TRXI on the wall over the anchors and reinstall the  
four anchor screws to attach the TRXI to the wall, as shown in

INSTALLATION  
3.6 CONNECTING THE TRXI TO THE P OWER SOURCE  
Note: The TRXI has a universal power supply. This allows you to  
connect the TRXI to power sources from 85 Vac to 264 Vac, 47-63 Hz.  
To connect the TRXI to the power source, plug the power cord into a  
grounded wall outlet. Turn on the power switch at the back panel of  
the TRXI. Verify that the P WR LED is lit, indicating that the TRXI is  
receiving power. After the TRXI runs a self test, the CP U LED blinks  
green indicating normal operation. If the LED remains red, the  
processor is faulty.  
3.7 CONNECTING THE NETWORK LOBE P ORT CABLING  
The TRXI-22/24 network lobe ports consist of unshielded RJ 45  
connectors that support UTP cabling. To connect a UTP segment from  
the TRXI to a station supporting STP cabling, you need a Type 3  
Media Filter available from Cabletron Systems (TRMF, TRMF-2).  
The TRXI-42/44 network lobe ports consist of shielded RJ 45  
connectors that support STP cabling. Shielded patch cables that adapt  
a shielded RJ 45 to a data connector (MIC) are available from  
Cabletron Systems (PN 9372057-8). These adapter/patch cables let  
you connect to an existing patch panel equipped with data connectors.

3.8 INSTALLING THE TP IM RI/RO MODULES  
TPIMs provide RI/RO trunk port connections that support various  
media for trunk cabling. You can attach different media types at the  
Ring-In port and Ring-Out port. For example, you can insert a  
TPIM-T1 as the Ring-In port and a TPIM-T4 as the Ring-Out port.  
The following sections explain how to set the Phantom Switch, set the  
RI/RO Switch, install the TPIM to the TRXI, and attach segments to  
the TPIM.  
Prior to connecting trunk cabling to the TPIMs, check the connectors  
for proper pinouts. Table 3-1 provides a cross-reference of pinouts for  
TPIMs used for Ring-In or Ring-Out applications.

3.8.1 Settin g th e TP IMs P h a n tom Sw itch a n d RI/RO Sw itch  
Before you install a TPIM, set the Phantom Switch to the appropriate  
setting. This switch enables the port to autowrap” if a trunk cable  
fails or is removed. Figure 3-11 shows the location of the Phantom  
Switch. If you attach a Cabletron hub to the TPIM, leave the switch at  
the factory default setting of 1. If you attach a Non-Cabletron device to  
the TPIM, use the 0 setting.  
Ensure that the Ring-In/Ring-Out Switch is in the factory default  
RI/RO position. The TRXI does not support the Station (S) setting at  
this time.  
Note: If the switch locations on your TPIM do not match the locations  
illustrated in Figure 3-11, refer to the TPIM Reference Card included

INSTALLATION  
3.8.5 Con n ectin g a Fiber Op tic Lin k Segm en t to th e TP IM-F 2  
or TP IM-F 3  
When connecting a fiber optic link segment to the TPIM-F2 or  
TPIM-F3 keep the following in mind:  
If you are connecting a fiber optic link segment with ST  
connectors to a TPIM-F2 with ST ports, keep in mind that ST  
connectors attach to ST ports much like BNC connectors attach  
to BNC ports. The connector is inserted into the port with the  
alignment key on the connector inserted into the alignment slot  
on the port. The connector is then turned to lock it down.  
The physical communication link consists of two strands of  
fiber optic cabling: the Transmit (TX) and the Receive (RX). The  
Transmit strand from the applicable port on the module will be  
connected to the Receive port of a fiber optic device at the other  
end of the segment. For example, TX of the applicable port on  
the module will go to RX of the other fiber optic device. The  
Receive strand of the applicable port on the module will be  
connected to the Transmit port of the fiber optic device. For  
example, RX of the applicable port on the module will go to TX  
of the other fiber optic device.  
It is recommended that you label the fiber optic cable to  
indicate which fiber is Receive and which is Transmit. When  
you buy fiber optic cable from Cabletron Systems, it is labeled  
so that: at one end of the cable, one fiber is labeled 1, and the  
other fiber is labeled 2. This pattern is repeated at the other  
end of the cable. If you did not purchase your cable from  
Cabletron Systems, be sure you have labeled your cable in the  
manner described above.  
Ca u tion : Do not touch the ends of the fiber optic strands, and do not let  
the ends come in contact with dust, dirt, or other contaminants.  
Contamination of the ends can cause problems in data transmissions. If  
the ends become contaminated, clean them with alcohol using a soft,  
clean, lint free cloth.

connect it to the network. It also describes LANVIEW and explains  
how to use the LCD to troubleshoot physical layer network problems.  
4.1 CHECKING THE INSTALLATION  
Perform the following to check the installation of the TRXI:  
1. Trace the ring path through the network to be sure that there are  
no breaks in the ring and that it is free from logical design errors.  
a. Check each cable connection.  
b. Verify the pinouts for every connection.  
c. Check the cable conductors for continuity. Cable testers are  
available for this task.  
d. Check that cable connections at patch panels and wall plates  
are secure.  
2. Check the network ring speed:  
a. Check the Ring Speed LED. Ensure the ring speed matches the  
station and cable specifications explained in Chapter 2.  
b. Be sure that all devices in the ring network are set to the same  
ring speed. Check all stations in the network.  
3. Ensure that the maximum cable length for EACH station and the  
maximum number of stations are not exceeded.  
When you complete each of these checks successfully, the TRXI is  
ready for normal operation. If problems occur, contact Cabletron  
Systems Technical Support.

5.3.2 Th e SNMP Com m u n ity Na m es Scr een  
The SNMP Community Names screen lets you set community names.  
Community names serve two purposes; they act as passwords to Local  
Management and they are agents of security control to your TRXI. You  
control TRXI access by establishing up to three levels of security  
authorization (Read Only, Read-Write, and Super-User). Only a user  
with Super-User access can change the device IP address and the  
community names.  
Ca u tion : Community Names are passwords to Local Management.  
Remember your Community Name.  
Local Management passwords accorded Read-Only and Read-Write  
access privileges are not allowed editing capabilities to some fields. In  
this case, the message AUTHORIZATION PROHIBITS ACCESS”

The Ring Security screen lets you control access to your token ring

ring security, the TRXI stores the MAC address of each station on the  
token ring network in a secure database or allowed list.” Only  
stations on the allowed list can enter the ring. The TRXI can store up  
to 250 station MAC addresses on the allowed list. The TRXI retains  
the allowed list in its battery-backed Non-Volatile Random Access  
Memory (NVRAM). If you power up or reset the TRXI, NVRAM  
retains the allowed list and automatically re-enables ring security.

Note: You should enable the Ring Security feature on only on e TRXI

You can select two modes of ring security; Alarm Only and  
Alarm/Remove. In the Alarm Only mode, new stations can enter the

LOCAL MANAGEMENT  
The trap/alarm includes the new stations MAC address so that you  
can decide if the new station should be allowed to remain on the ring.  
If you select the Alarm/Remove mode, ring security sends a Remove  
MAC Frame Command” to new stations attempting to enter the ring,  
and a trap/alarm to the NMS informing it of the action taken. If the  
Remove MAC Frame Command fails to remove the new station after  
three attempts, ring security sends a trap/alarm to the NMS  
informing it that the station could not be removed.”  
The following section provides a brief explanation of each field and  
command on the Ring Security screen and instructions for using them.  
Note: Before you begin, you must set up the TRXIs SNMP Traps screen  
to designate which Network Management Stations receive trap/ alarms  
(refer to the SNMP Traps screen section). This ensures that trap/ alarms  
generated by ring security arrive at the appropriate destination.  
Sta tion Ad d r ess  
This field lists the MAC address of each station on the ring security  
allowed list. This field can lists up to 250 MAC addresses on 22 local  
management screens.  
Stn Ed it  
The Station Edit command lets you add or delete stations from the  
allowed list. Use the Stn Edit command for single entry edits to the  
allowed list (refer to the Alarm Only security mode definition for  
information about adding multiple users).  
Secu r ity Mod e  
This command lets you set the Security Mode for the ring. Security  
Modes determine the level of ring security. You can select the following  
Security Modes:  
Disa bled - This is the factory default setting. Use this option  
to temporarily disable ring security so that new stations can  
enter the ring.  
Ala r m On ly - In this mode, ring security allows new stations  
to enter the ring. When a station enters the ring, ring security  
sends a station added” trap/alarm to the Network  
Management Station.  
Page 5-18

LOCAL MANAGEMENT  
The station added” trap message includes the new stations  
MAC address so that you can decide if the new station should  
be allowed on the ring.  
To add multiple users to the ring, temporarily disable ring  
security using the Disable mode, then select the Alarm Only  
mode to re-enable ring security. Ring Security stores the MAC  
address of each station on the ring to the allowed list. This  
saves you from entering MAC addresses one at time using the  
Stn Edit command. Refer to Building the Allowed List” for  
instructions.  
Ala r m /Rem ove - This is the highest level of ring security.  
When in the Alarm/Remove mode, ring security sends a  
Remove MAC Frame Command” to new stations attempting to  
enter the ring, and a trap/alarm to the NMS informing it of the  
action taken. The Remove MAC Frame Command” tries to  
automatically remove the station from the ring. If it cannot  
remove the station from the ring after three attempts, it sends  
a trap/alarm to the NMS informing it that the station could  
not be removed.”  
SAVE/EXECUTE  
This command saves all security mode changes to the TRXIs NVRAM.  
You must use the SAVE/EXECUTE command for your changes to take  
effect.

LOCAL MANAGEMENT  
F r a m es Received  
Displays the total frames detected on the ring since the TRXI was last  
powered on or reset.  
KBytes Received  
Displays the kilobyte sum of all frames detected on the TRXI since it  
was last powered up or reset.  
Er r or s Received  
Displays the total Isolating and Non-Isolating Errors detected by the  
TRXI.  
Bea con Sta tes  
Displays the total beacon states detected by the TRXI. Stations  
transmit beacons when they detect bit streaming or signal loss on the  
ring.  
Rin g P u r ges  
Displays the total ring purge frames transmitted by the active  
monitor.  
Active Mon itor Ch a n ges  
Displays the number of times a different station has been active  
monitor.  
ISOLATING ERRORS  
Isolating Errors are soft” ring errors that report the domain of a fault  
(that is, you can isolate the faults region to the transmitting adapter,  
the receiving adapter, and the components - cabling and wiring  
concentrators - between the two).  
Lin e Er r or s  
Displays the total line errors detected by the TRXI. Line Errors  
are corrupted frames that are detected by a node. This type of  
error normally occurs when stations enter and leave the ring.  
This error can also indicate a problem with the receiver of the  
reporting node, or the transmitter of its Nearest Active  
Upstream Neighbor (NAUN), or the cabling and hub hardware  
between them.  
Page 5-23

LOCAL MANAGEMENT  
Bu r st Er r or s  
Displays the total burst errors detected by the TRXI. Burst  
Errors are the absence of clocking signals at a nodes receiver.  
This error normally occurs when stations enter or leave the ring  
with the absence of phantom current.  
This error can also indicate a problem with the receiver of the  
reporting node, or the transmitter of its NAUN, or the cabling  
and hub hardware between them.  
AC Er r or s  
Displays the total Address Recognized/Frame Copied errors.  
This indicates that the reporting NAUN is faulty. The node  
cannot set the address recognized indicator and/or frame copied  
indicator bits in the frame which it has copied. This leaves the  
downstream node with an incorrect NAUN address.  
Abor t Tr a n sm it Er r or s  
Displays the total abort delimiter frames transmitted by a  
station. This indicates that either the reporting node has  
detected an error on itself, or there is an error with its NAUN, or  
the cabling and wiring hubs between them.  
In ter n a l Er r or s  
Displays the total internal errors detected by the adapters  
hardware and/or firmware. These errors cause the adapter to  
remove itself from the ring and indicates a problem with the  
adapter hardware or firmware (possibly an inoperable chipset,  
timers, or counters).  
RING INF ORMATION  
Ring Information provides ring status information.  
Active Mon itor Ad d r  
Displays the MAC address of the active monitor. The active  
monitor initiates recovery procedures from various error  
situations.  
Rin g Sta tu s  
This field lists the current status of the ring being monitored by  
the TRXI. TRXI displays the following ring status conditions:  
Page 5-24  
Download from Www.Somanuals.com. All Manuals Search And Download.  
LOCAL MANAGEMENT  
Un k n ow n , Indicates the state of the ring cannot be  
detected by the management station.  
Closed , Indicates that the management station is not  
inserted into the ring and therefore cannot determine the  
ring state.  
Nor m a l, Indicates the ring is running with no problems,  
and tokens are being detected by the management  
station.  
P u r ge, Indicates that the active monitor has issued a  
ring purge command. Communications will be restored  
when a new token is released.  
Con ten tion , Indicates that the ring has entered into the  
active monitor contention process to determine a new  
active monitor for the ring.  
Bea con in g, Indicates that the management station has  
detected a beacon frame.  
Lobe Fa il, Indicates that a station failed the lobe self-  
test when it attempted to insert into the ring.  
Rin g Nu m ber  
Displays the number of rings on the network.  
Sta tion s on a Rin g  
Displays the number of stations inserted into the ring.  
P or ts En a bled  
Displays the number of network lobe ports enabled.  
Rin g Sp eed  
Displays the ring speed of the TRXI as either 4 Mb/s or 16 Mb/s.  
NON-ISOLATING ERRORS  
Non-Isolating Errors are soft error” conditions that could have been  
caused by any station on the ring. Their fault domain cannot be  
detected.  
Lost F r a m e Er r or s  
Displays the total number of Lost Frame Errors. These errors  
occur when the adapter fails to receive the end of the frame it  
has just transmitted. The frame was lost somewhere on the ring  
but there is no way to pinpoint where. This can be caused by  
stations entering or leaving the ring.  
Page 5-25  
Download from Www.Somanuals.com. All Manuals Search And Download.  
LOCAL MANAGEMENT  
F r a m e Cop ied Er r or s  
Displays the total number of Frame Copied Errors. These errors  
occur when a station finds a frame with its address as the  
destination, but finds the address recognized indicator bits not  
set to zero. This indicates a possible duplicate address.  
Rcvr Con gestion Er r or s  
Displays the total number of Rcvr Congestion Errors. This  
indicates a station is receiving/repeating a frame and recognizes  
a frame addressed to it, but has no buffer space available for the  
frame.  
Tok en Er r or s  
Displays the total number of Token Errors. Token Errors occur  
when an active monitor does not see a token circulating on the  
ring before its TVX (Timer, Valid Transmission) time expires  
(e.g. a lost frame error has occurred), or sees a recirculating  
frame or token. The active monitor is responsible for purging the  
ring and issuing a new token.  
F r equ en cy Er r or s  
Displays the total number of frequency errors. This indicates  
that the frequency of the incoming signal deviates excessively  
from the adapters onboard crystal oscillator. It could indicate an  
error in this nodes oscillator, the active monitor, or any node in  
between. When the node detects a frequency error, it enters the  
monitor contention process.  
Tota l  
Displays a running total of statistics beginning from the TRXIs  
last power-on.  
Accu m u la te  
Initiates a new statistic count. The TRXI begins totaling  
statistics after you select accumulate.  
Delta  
Displays the total statistics beginning at the last screen Refresh.  
Refr esh 99sec  
Displays the time interval between screen counter updates. You  
can choose refresh intervals in increments of 3 seconds, with the  
maximum interval being 99 seconds.

LOCAL MANAGEMENT  
Th e Secu r ity Access Level  
Each MIB component that the TRXI supports (e.g., RMON, DLM, etc.)  
has its own “password” for each possible level of access (ranging from  
Basic Read-Only to Super-User).  
Note: A complete list of Super-User Community Names (also called  
Community Strings) resides in the Cabletron proprietary chassis MIB.  
The MIB group chCompName provides the names of the MIB  
components. The MIB group chCompSUCommStr provides individual  
MIB component Community Names/ Strings.  
The component information corresponds numerically – by last digit. In  
other words, each instance (i.e., OID element) in the chCompName  
group indicates its match in the chCompSUCommStr group.  
In order to access a specific MIBs components, you must set the  
appropriate MIB password in the COMMUNITY NAME field.  
Note: The default Super-User password (public) allows you to access all  
MIB components. To change the SNMP Tools screen COMMUNITY  
NAME field, you must have Super-User access to Local Management.  
To set the SNMP Tools screen COMMUNITY NAME:  
1. Use the arrow keys to highlight the field to the right of  
COMMUNITY NAME.  
2. Enter the Community Name necessary for Super-User access for  
any specific MIB (e.g., channelA for Repeater Rev. 4 MIB).  
3. Press the Retu r n key. The Community Name changes.
