Introduction
The CheetahSwitch Workgroup-3726M is perfect for moving workgroups from
conventional 10 Mbps Ethernet to multiple-segment 100 Mbps Fast Ethernet, and
for consolidating your network equipment into a single, clean, efficient, and
super-fast switch stack. This switch system delivers dedicated 100 Mbps links to
each attached LAN segment (independent collision domain) or to any PC attached
directly to the stack – all with conventional cabling and adapters. It completely
eliminates the bottlenecks of shared 10 Mbps Ethernet networks by providing a wide
bandwidth of up to 8.8 Gbps per switch, and a stack backplane that can operate at
up to 9.6 Gbps. This makes it ideal for increasing the throughput of interconnected
Ethernet and Fast Ethernet hubs or server farms.
This switch includes three slots on the rear panel for various modules:
• The upper slot is for an SNMP/RMON Management Module. The stack supports only
one management agent.
• The lower right slot is for optional media expansion modules, including a dual-port
100 Mbps fiber optic module that can be connected to a remote site up to
2 kilometers (1.24 miles) away, or a single-port Gigabit module that can be used to
uplink to a collapsed Gigabit backbone or for a high-speed server connection.
• The lower left slot is for either an optional media expansion module or Stacking
Module. (Up to four switch units can be stacked together using Stacking Modules.)
When the Management Module is installed, this system can provide a wide array of
advanced features:
• Master agent module manages entire stack in-band or out-of-band
• Backup agent module provides fault tolerance*
• Supports Telnet, SNMP/RMON and Web-based interface
• Four-group RMON (including Statistics, History, Alarms and Events)
• Spanning Tree Algorithm for redundant paths between switches
• VLAN support for up to 256 groups, port-based or with 802.1Q VLAN tagging
• GVRP for automatic VLAN learning*
• IGMP multicast filtering
• Quality of Service supports two levels of priority with Weighted Fair Queueing
• Configurable broadcast storm control
• Port mirroring (for real-time debugging without affecting the target port)
• Port trunking (up to 5 trunks per switch or 12 trunks for the entire stack, each trunk
contains 2~4 ports)
* This feature is not supported in the current firmware release.
The agent module allows you to configure or monitor the switch using the embedded
management program or SNMP/RMON applications. To manage the switch, you can
make a direct connection to the console port. You can also make a network
connection to manage the switch using Telnet, the Web agent, or Accton’s free
Windows-based network management software called AccView/Open.

Description of Hardware
The base unit contains 24 10BASE-T/100BASE-TX ports, plus three slots on the
rear panel for various modules. A Management Module can be installed in the upper
slot on the rear panel (see “Installing a Management Module” on page 4). The
lower-left slot can be used for an optional media expansion module or Stacking
Module, while the lower-right slot can be used for a media expansion module. Note
that the media expansion modules include a Fast Ethernet fiber optic module with
two 100BASE-FX (SC type) ports or a one port Gigabit 1000BASE-SX (SC type), or
1000BASE-LX uplink module.
All RJ-45 ports on the base unit operate at 10 or 100 Mbps, and support
auto-negotiation of speed, duplex mode (i.e., half or full duplex), and flow control.
The 1000BASE-SX and 1000BASE-LX ports are fixed at 1000 Mbps but
auto-negotiate duplex mode. The 100BASE-FX module is fixed at the 100 Mbps, full
duplex. All media types can auto-negotiate flow control.
Note that when using auto-negotiation, the speed, transmission mode and flow
control can be automatically set if this feature is also supported by the attached
device. Otherwise, these items can be manually configured for any connection.
The base unit also includes a display panel for key system and port indications that
simplify installation and network troubleshooting.

Mounting the Switch
This switch can be placed directly on your desktop, or mounted in a rack.
Before you start installing the switch, make sure you can provide the right operating
environment, including power requirements, sufficient physical space, and proximity
to other network devices that are to be connected. Verify the following installation
requirements:
• Power requirements: 100 to 240 VAC (± 10%) at 50 to 60 Hz (± 3Hz). The switch’s
power supply automatically adjusts to the input voltage level.
• The switch should be located in a cool dry place, with at least 10 cm. (4 in.) of space
on the sides for ventilation.
• Place the switch out of direct sunlight, and away from heat sources or areas with a
high amount of electromagnetic interference.
• If you intend to mount the switch in a rack, make sure you have all the necessary
mounting screws, brackets, bolts and nuts, and the right tools.
• Check if network cables and connectors needed for installation are available.
Stacking Switches on a Flat Surface
The CheetahSwitch can be stacked
anywhere there is enough flat space, such
as on a table or desktop.

Quick Installation Guide
Mounting Switches in a Rack
Please comply with the following instructions to ensure that your switch is securely
mounted in the rack.
1. Use a standard EIA 19-inch rack.
2. Use the brackets and screws supplied in
the rack mounting kit.
3. Use a cross-head screwdriver to attach the
brackets to the side of the switch.

4. Position the switch in the rack by lining up
the holes in the attached brackets with the
appropriate holes on the rack, and then
use the rack-mount screws to mount the
switch in the rack.
Installing a Management Module
One Management Module is required to manage all of the switches in the stack. A
Management Module only installs in a switch’s rear-panel upper slot, do not try to
install it in either of the two lower slots.
You can install a Management Module as described below:
1. Disconnect power to the switch (the modules are not hot-swappable).
2. Remove the face plate on the switch’s upper slot by removing the two screws
with a flat-head screwdriver.
3. Before opening the package that contains the module, touch the bag to the
switch casing to discharge any potential static electricity.
4. Remove the module from the anti-static shielded bag.
5. Holding the module level, gently push it all the way into the slot along the guide
rails, ensuring that it firmly engages with the connector.
6. If you are sure the module is properly mated with the connector, tighten the
retainer screws to secure the module in the slot.
Caution: The slide-in modules are not hot-swappable. Be sure you power off the switch
before installing any of these modules.
Installing Optional Media and Stacking Modules
The two lower slots on the rear panel of the switch are provided for various optional
media expansion modules (100BASE-FX or Gigabit) or Stacking Modules. The
100BASE-FX fiber optic module can be used to connect to remote sites, and a
Gigabit module can be used as a network backbone. You can install the media
expansion modules in either of the two lower slots, but the Stacking Module must
only be installed in the lower-left slot.

installing any of these modules.
Connecting to the Stack’s Backplane
Plug one end of the stack cable (provided with the
package) in the “Down” port of the top unit and the
other end to the “Up” port of the next unit. Repeat this
step for each unit in the stack. Form a simple chain
starting at the Down port on the top switch and ending
at the Up port on the bottom switch (stacking up to 4
units).

Quick Installation Guide
Connecting the Switch System
The CheetahSwitch Workgroup-3726M provides 24 RJ-45 ports on the base unit.
Each of these ports supports a connection to 10 Mbps Ethernet or 100 Mbps Fast
Ethernet, and supports full or half-duplex operation. The transmission speed for
each port is automatically set by the switch to match the highest speed supported by
the connected device. The transmission mode can be set for each port using
auto-negotiation (if also supported by the attached device). However, if the device
attached to any port on the switch does not support auto-negotiation, you can
manually configure the transmission mode via the console port on the rear panel, or
via an in-band connection (including Telnet, the Web agent or management
software).
Making a Connection to an RJ-45 Port
You can use straight-through twisted-pair cable to connect any RJ-45 (MDI-X) port
on the switch to any device that uses a standard network interface such as a
workstation or server, or to a network interconnection device such as a bridge or
router (depending on the port type implemented).
1. Prepare the network devices you wish to network. Make sure you have installed
10BASE-T or 100BASE-TX network interface cards for connecting to the
switch’s RJ-45 (MDI-X) station ports.
2. Prepare straight-through shielded or unshielded twisted-pair cables with RJ-45
plugs at both ends. Use 100-ohm Category 3, 4 or 5 cable for standard
10 Mbps Ethernet connections, or 100-ohm Category 5 cable for 100 Mbps
Fast Ethernet connections.
3. Connect one end of the cable to the RJ-45 port of the network interface card,
and the other end to any available RJ-45 port on the switch. All RJ-45 ports
RJ-45 plug, be sure the tab on the plug clicks into position to ensure that it is
properly seated. Using the switch in a stand-alone configuration, you can
network up to 24 end nodes.
Caution: Do not plug a phone jack connector into any RJ-45 port. This may damage the
switch. Instead, use only twisted-pair cables with RJ-45 connectors that
conform with FCC standards.
Notes: 1. When connecting to another compatible switch or hub, use straight-through
cable to connect to an MDI port on the other device. You may also attach to
MDI-X station ports at both ends if you use crossover cabling. (Refer to “Port
and Cable Assignments” on page 15 for a description of crossover cable.)
2. Make sure each twisted-pair cable does not exceed 100 meters (328 feet).
3. We advise using Category 5 cable for all network connections to avoid any
confusion or inconvenience in the future when you upgrade attached devices
to Fast Ethernet.
Restrictions on Cascade Length - The IEEE 802.3 standard recommends
restricting the number of hubs (i.e., repeaters) cascaded via twisted-pair cable to 4;
while IEEE 802.3u provides even stricter recommendations for Fast Ethernet.
Therefore, when cascading devices other than this switch, please refer to the
accompanying documentation for cascade restrictions. However, note that because
6
Download from Www.Somanuals.com. All Manuals Search And Download.
Installing the Switch
switches break up the path for connected devices into separate collision domains,
you should not include the switch or connected cabling in your calculations for
cascade length involving other devices.
Connecting to a 100BASE-FX Port
If you connect fiber cable to the
100BASE-FX module, be sure you use an
SC-type connector. When inserting the cable, be sure the tab on the plug clicks into
position to ensure that it is properly seated. If you use an SC-to-ST converter, run
cable from the Rx (Tx) port on the module to the Tx (Rx) port on the target device.
Note that the fiber optic ports operate only at 100 Mbps, full duplex. In this mode,
you can run a fiber optic link up to 2 kilometers (1.24 miles).
Caution: The media expansion modules are not hot-swappable. Be sure you power off
the switch before installing any of these modules.
Note: As a general rule, the length of fiber optic cable for a single switched link should
not exceed 2 kilometers (1.24 miles). However, budget constraints must also be
considered when calculating the maximum cable length for your specific
environment.
Connecting to a Gigabit Fiber Optic
Port
When connecting fiber cable to a Gigabit fiber-optic port on the switch, be sure you
use an SC-type connector. Follow the steps below.
Warning: This switch uses lasers to transmit signals over fiber optic cable. The lasers are
compliant with the requirements of a Class 1 Laser Product and are inherently
eye safe in normal operation. However, you should never look directly at a
transmit port when it is powered on.
1. Remove and keep the SC port’s rubber cover. When not connected to a fiber
cable, the rubber cover should be replaced to protect the optics.
2. Check that the fiber terminators are clean. You can clean the cable plugs by
wiping them gently with a clean tissue or cotton ball moistened with a little
ethanol. Dirty fiber terminators on fiber optic cables will impair the quality of the
light transmitted through the cable and lead to degraded performance on the
port.
3. Connect one end of the cable to the SC port on the switch and the other end to
the SC port on the other device. Since SC connectors are keyed, the cable can
be attached in only one orientation. When inserting the cable, be sure the tab
on the plug clicks into position to ensure that it is properly seated.
All the SC-type ports operate at 1000 Mbps with support for auto-negotiation of
duplex mode (full/half) and flow control. Also note the maximum length for

Powering On the Switch
1. Plug the power cord into the power socket on the rear of the switch, and the
other end into a power outlet. (If you have purchased a redundant power
supply, plug it into the “DC INPUT” receptacle on the rear of the switch.)
2. Check the LED marked Power on the front panel to see if it is on. The unit will
automatically select the setting that matches the connected input voltage.
Therefore, no additional adjustments are necessary when connecting it to any
input voltage within the range marked on the rear panel.
3. The switch performs a self-diagnostic test upon power-on. (Note that this test
takes several minutes to complete.)
Note: The unit supports a “hot remove” feature which permits you to connect or
disconnect twisted-pair or fiber cables without powering off the switch and without
disrupting the operation of the devices attached to the switch.

Verifying System Operation
Verify that the stack has at least one Management Module correctly installed and
operating. The “Mgmt” LED on the switch that contains the Management Module
should be on, indicating that the module is installed and operating correctly.
Verify that the stack connections are operating correctly. Each switch in the stack
has it’s own unique unit ID (a number from 1 to 4) displayed by the front-panel LCD
labeled “Switch ID.” If any switch in the stack displays a flashing or unstable unit ID
for more than 30 seconds, you should check the following items:
• Reset the stack by powering off all switches and then powering them back on.
• Be sure that all Stacking Modules are correctly installed in each switch’s lower-left
slot and the stacking cables are properly attached.
Verify that any optional modules are installed correctly. The Module 1 or Module 2
“Status” LEDs on the switch panel should be on, indicating that the modules are
installed and operating correctly.
Verify that all attached devices have a valid connection. The switch monitors the link
status for each port. If any device is properly connected to the switch and
transmitting a link signal, the Link indicator will light up for the corresponding port. If
the Link indicator fails to light when you connect a device to the switch, check the
following items:
• Be sure all network cables and connectors are properly attached to the connected
device and the switch.

Quick Installation Guide
• See if your cable is functioning properly by using it for another port and attached
device that displays valid indications when connected to the network.
• Be sure no twisted-pair cable exceeds 100 meters (328 feet). 100 Mbps fiber cable
should be under 2 kilometers (1.24 miles). The maximum length for fiber optic
Gigabit connections is listed in the table on the preceding page.
Applications
This switch segments your network, significantly increasing both bandwidth and
throughput. Any port on the switch can be attached to a hub (a shared collision
domain) or provide a dedicated link to a single network device (such as a
workstation or server). When a port on the switch is connected to a hub (a 10 or 100
Mbps repeater), the bandwidth provided by that port is shared by all the devices
connected to the attached hub. However, when a port is connected to an end node
or to a device that breaks up the collision domain (e.g., another switch, bridge or
router), the attached device has access to the full bandwidth provided by that port.
Bridging Functions - This switch provides fully transparent bridging functions.
It automatically learns node addresses, that are subsequently used to filter and
forward all traffic based on the destination address. When traffic passes between
devices attached to the same shared collision domain, those packets are filtered
from the switch. But when traffic must be passed between unique segments (i.e.,
different ports on the switch), the high-speed switching fabric forwards the packets
at near zero latency.
Switching Functions - Store-and-forward switching is used to forward traffic to
other ports. This scheme ensures data integrity and provides a clean data stream.
Flexible Configuration - This switch is not only designed to segment your network,

Power and Cooling Problems
If the power indicator does not turn on when the power cord is plugged in, you may
have a problem with the power outlet, power cord, or internal power supply as
explained in the previous section. However, if the unit powers off after running for a
while, check for loose power connections, power losses or surges at the power outlet,
and verify that the fans on the right side of the unit are unobstructed and running
prior to shutdown. If you still cannot isolate the problem, then the internal power
supply may be defective. In this case, contact your Accton distributor for assistance.
Installation
Verify that all system components have been properly installed. If one or more
components appear to be malfunctioning (e.g., the power cord or network cabling),
test them in an alternate environment where you are sure that all the other
components are functioning properly.
