Installation Guidelines
Note This product is not intended to be connected directly or indirectly by any means whatsoever to interfaces
of public telecommunications networks.
Consider these guidelines before you install the switch module:
• Fill any unoccupied interconnect bays or any unoccupied power module bays in the blade enclosure
with filler modules.
• Identify the bays in which you will insert the switch modules. Plan to install the first switch module
in bay 1, the second in bay 2, and so on up to bay 4, if possible.
See the IBM blade enclosure documentation for more information about the specific enclosure
model, the interconnect bay options, and the port mapping between the blade enclosure and the
switch modules.
• For switch stacks, you should first install and configure the switch module that will be the stack
master before installing any additional switch modules. See the
page 2-6 for more information.
• The orange release latch on the switch module means that it is hot-swappable. To maintain proper
system cooling, you must replace a hot-swap switch module within 1 minute of removal.
Preparing for Installation

Creating Switch Stacks
Creating Switch Stacks
This section is only for Catalyst Switch Module 3110G and 3110X and is optional.
A switch stack is a set of up to nine stacking-capable switch modules that are connected through their
StackWise Plus ports. One switch module controls the operation of the stack and is called the stack
master. The stack master and the other switch modules in the stack are stack members. Layer 2 and
Layer
3 protocols present the entire switch stack as a single entity to the network. When switch modules
are not stacked, each acts as a standalone switch module.
Caution The Catalyst Switch Module 3110G and 3110X do not support switch stacks with other types of blades
switches as members. Combining the switch module with other types of blade switches in a switch stack
might cause the switch module to work improperly or to fail.
Stacking Guidelines
Before you connect the switch modules in a stack, observe these stacking guidelines:
• You should install the stack master switch module and run the initial setup program on that switch
module before you connect the StackWise Plus cables to other stack members. We recommend that
you assign the highest priority value to the switch module that you prefer to be the stack master. This
ensures that the switch module is re-elected as stack master if a re-election occurs. As you add new
switch modules to the stack, they automatically become stack members.
Chapter 2 Switch Module Installation
• When you connect the StackWise Plus cables and create a stack, only the status of the stack master
Fa0 interface appears in the switch module configuration, and it shows that the port is shut down
while in stack mode.
• You can stack a combination of up to nine switch modules. You can stack only the Catalyst Switch
Modules 3110G and 3110X; other blade switches are not supported.
• Although the StackWise Plus ports are numbered (1 and 2), you do not need to make specific port
connections between switch modules.
• For conditions that might cause a stack master re-election and for general concepts and procedures
to manage switch stacks, see the “Managing Switch Stacks” chapter in the switch module software
configuration guide on Cisco.com.
• Before connecting, verify the StackWise Plus cable length. Depending on your configuration, you
might need different sized cables. If you do not specify the length of the StackWise Plus cable when
you order your product, the 1-meter cable is supplied. If you need the 0.5-meter cable or the 3-meter
cable, you can order these StackWise Plus cables from your supplier:
–
CAB-STK-E-0.5M= (0.5-meter cable)
–
CAB-STK-E-1M= (1-meter cable)
–
CAB-STK-E-3M= (3-meter cable)

Connecting a Switch Stack
Follow these steps:
Step 1 Install the member switch modules if you have not already done so.
Step 2 Remove the dust covers from the StackWise Plus cables, and store them for future use.
Step 3 Verify that cables are aligned as shown in Figure 2-3. (The cables are keyed for correct insertion.)
Figure 2-3 Connecting the StackWise Plus Cables
Creating Switch Stacks
Step 4 Insert the cable into the StackWise Plus port on the front panel of the switch module. Insert the other end
of the cable into the connector of the other switch module.
Always use a Cisco-approved StackWise Plus cable to connect the switch modules.
Caution The new stack-member switch module restarts when you connect the StackWise Plus cables.
Step 5 Configure the member switch modules through the master switch module by using the CLI through the
console port of any stack member.
To remove the StackWise Plus cables, grasp the tab on the cable connector, and gently pull straight out.
When you remove the StackWise Plus cables, replace the dust covers to protect them from dust.
Caution Removing and installing the StackWise Plus cable can shorten its useful life. Do not remove and insert
the cable more often than is absolutely necessary.

Installing Devices in the 10-Gigabit Ethernet Slot
This section describes how to install and remove X2 transceiver modules.
Use only Cisco X2 transceiver modules with the switch modules. Each Cisco module has an internal
serial EEPROM that is encoded with security information. This encoding provides a way for Cisco to
identify and validate that the module meets the requirements for the switch module.
For more information about installing, removing, cabling, and troubleshooting X2 transceiver modules,
see the module documentation that shipped with your device. For module cable specifications, see
Appendix B, “Connector and Cable Specifications.”
Installing an X2 Transceiver Module
When installing an X2 transceiver module, observe these general precautions:
• Do not remove the module slot cover from the 10-Gigabit Ethernet slot until you are ready to install
an X2 transceiver. Either a module or the module slot cover must be installed in the slot at all times.
• Do not remove the dust plugs from the fiber-optic X2 transceiver modules or the rubber caps from
the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the module
ports and cables from contamination and ambient light.
• Removing and installing an X2 module can shorten its useful life. Do not remove and insert any X2
module more often than is absolutely necessary.
• To prevent ESD damage, follow your normal board and component handling procedures when
connecting cables to the switch module and other devices.
To install an X2 transceiver module, follow these steps:
Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.
Step 2 Remove the module from the protective packaging.
Step 3 Remove the 10-Gigabit Ethernet module slot cover and save.
Step 4 Align the transceiver module in the module slot (Figure 2-7).

Connecting Devices to the Ethernet Ports
The 10/100/1000 Ethernet ports use standard RJ-45 connectors with Ethernet pinouts. The maximum
cable length is 328 feet (100 meters). The 100BASE-TX and 1000BASE-T traffic requires Category
Category
Caution Category 5e and Category 6 cables can store high levels of static electricity. Always ground the cables
to a suitable and safe earth ground before connecting them to the switch module or other devices.
The autonegotiation feature is enabled by default on the switch module. At this setting, the
switch-module ports configure themselves to operate at the speed of attached device. If the attached
device does not support autonegotiation, you can explicitly set the switch-module port speed and duplex
parameters. To maximize performance, either let the ports autonegotiate both speed and duplex, or set
the port speed and duplex parameters on both ends of the connection.
For simplified cabling, the automatic medium-dependent interface crossover (auto-MDIX) feature is
enabled by default on the switch module. With auto-MDIX enabled, the switch module detects the
required cable type for copper Ethernet connections and configures the interface accordingly. Therefore,
you can use either a crossover or a straight-through cable for connections to a switch-module
10/100/1000 Ethernet port regardless of the type of device on the other end of the connection.

Diagnosing Problems
The LEDs on the front panel provide troubleshooting information about the switch module. They show
POST failures, port-connectivity problems, and fault indications. You can also get information from the
device manager, from the CLI, or from an SNMP workstation. See the switch module software
configuration guide and the command reference guide on Cisco.com or the documentation that came
with your SNMP application for details.

Verify Switch Module POST Results
As the switch module powers on, it begins the power-on self-test (POST), a series of tests that runs
automatically to ensure that the switch module functions properly. It might take several minutes for the
switch module to complete POST. When POST completes successfully, the System LED remains green.
The other LEDs turn off and return to their operating status. If the switch module fails POST, the System
LED is amber.
Note POST failures are usually fatal. Contact your Cisco technical support representative if your switch
module does not pass POST.
Verify Switch Module LEDs
If you have physical access to the switch module, look at the port LEDs for troubleshooting information
about the switch module. See the
LED colors and their meanings.

Diagnosing Problems
Verify Switch Module Connections
Review this section when troubleshooting switch module connection problems.
Bad or Damaged Cable
Always evaluate the cable for marginal damage or failure. A cable might be just good enough to connect
at the physical layer, but it could corrupt packets as a result of subtle damage to the wiring or connectors.
You can identify this situation because the port has many packet errors or the port constantly flaps (loses
and regains link). You should:
• Inspect or exchange the copper or fiber-optic cable with a known, good cable.
• Look for broken or missing pins on cable connectors.
• Rule out any bad patch panel connections or media convertors between the source and destination.
If possible, bypass the patch panel or eliminate faulty media convertors (fiber-optic-to-copper).
• Try the cable in another port or interface, if possible, to see if the problem follows the cable.
• StackWise Plus cable: remove and inspect the cable and StackWise Plus port for bent pins or
damaged connectors. If the StackWise Plus cable is bad, replace it with a known good cable.
Chapter 3 Troubleshooting
Ethernet and Fiber Cables
Make sure that you have the correct cable type for the connection:
• For Ethernet, use Category 3 copper cable for 10 Mb/s UTP connections. Use Category 5,
Category
• For fiber-optic connectors, verify that you have the correct cable for the distance and port type. Make
sure that the connected device ports both match and use the same type encoding, optical frequency,
and fiber type. For more information about cabling, see the
Module Cable Specifications” section on page B-3.
• For copper connections, determine if a crossover cable was used when a straight-through was
required or the reverse. Enable auto-MDIX on the switch module, or replace the cable. See
for recommended Ethernet cables.
Link Status
Verify that both sides have link. A single broken wire or one shutdown port can cause one side to show
link, but the other side does not have link.
A link LED does not guarantee that the cable is fully functional. The cable might have encountered
physical stress that causes it to function at a marginal level. If the link light for the port does not come on:
• Connect the cable from the switch module to a known good device.
• Make sure that both ends of the cable are connected to the correct ports.

• Verify that both devices have power.
• Verify that you are using the correct cable type. See Appendix B, “Connector and Cable
Specifications” for more information.
• Look for loose connections. Sometimes a cable appears to be seated, but is not. Disconnect the cable,
and then reconnect it.

OL-12192-01
Chapter 3 Troubleshooting
Transceiver Issues
Use only Cisco X2 transceiver modules on the switch module. Each Cisco module has an internal serial
EEPROM that is encoded with security information. This encoding provides a way for Cisco to identify
and validate that the module meets the requirements for the switch module. Evaluate these items:
• Bad or wrong X2 transceiver module. Exchange suspect module with known good module. Verify
that the module is supported on this platform. (The switch module release notes on Cisco.com list
the X2 modules that the switch module supports.)
• Use the show interfaces privileged EXEC command to verify the port or module error-disabled,
disabled, or shutdown status. Re-enable the port if needed.
• Make sure that all fiber connections are properly cleaned and securely connected.
• For CX4 module connections, make sure that cable routing does not violate the minimum allowed
cable-bend radius. See the module documentation for specific cabling requirements.
• For LX4 modules, we recommend a mode conditioning patch for MMF applications.
Port and Interface Settings
Diagnosing Problems
An obvious but sometimes overlooked cause of port connectivity failure is a disabled port. Verify that
the port or interface is not disabled or powered down for some reason. If a port or interface is manually
shut down on one side of the link or the other side, the link does not come up until you re-enable the
port. Use the show interfaces privileged EXEC command to verify the port or interface error-disabled,
disabled, or shutdown status on both sides of the connection. If needed, re-enable the port or the
interface.
Ping End Device
Test the end device by pinging from the directly connected switch module first, and then work your way
back port by port, interface by interface, trunk by trunk, until you find the source of the connectivity
issue. Make sure that each switch module can see the end device MAC address in its
Content-Addressable Memory (CAM) table.
Spanning Tree Loops
Spanning Tree Protocol (STP) loops can cause serious performance issues that look like port or interface
problems. In this situation, the switch module bandwidth is used over and over again by the same frames,
leaving little room for legitimate traffic.
Loops can be caused by a unidirectional link. A unidirectional link occurs whenever the traffic sent by
the switch module is received by its neighbor, but the traffic from the neighbor is not received by the
switch module. A broken fiber-optic cable, other cabling, or a port issue could cause this one-way
communication.
OL-12192-01
You can enable UniDirectional Link Detection (UDLD) on the switch module to help identify
difficult-to-find unidirectional link problems. UDLD supports two modes of operation: normal (the
default) and aggressive. In normal mode, UDLD detects unidirectional links due to misconnected
interfaces on fiber-optic connections. In aggressive mode, UDLD also detects unidirectional links due
to one-way traffic on fiber-optic and twisted-pair links and due to misconnected interfaces on fiber-optic
links. For information about enabling UDLD on the switch module, see the “Understanding UDLD”
section in the software configuration guide for this release.

Resetting the Switch Module
Verify Switch Module Performance
Review this section when troubleshooting switch module performance problems.
Speed, Duplex, and Autonegotiation
If the port statistics show a large amount of alignment errors, frame check sequence (FCS), or
late-collisions errors, this might mean a speed or duplex mismatch.
A common issue with speed and duplex is when the duplex settings are mismatched between two switch
modules, between a switch module and a router, or between the switch module and a workstation or
server. This can happen when manually setting the speed and duplex or from autonegotiation issues
between the two devices. A mismatch occurs under these circumstances:
• A manually set speed or duplex parameter is different from the manually set speed or duplex
parameter on the connected port.
• A port is set to autonegotiate, and the connected port is set to full duplex with no autonegotiation.
To maximize switch module performance and ensure a link, follow one of these guidelines when
changing the settings for duplex and speed:
Chapter 3 Troubleshooting
• Let both ports autonegotiate both speed and duplex.
• Manually set the speed and duplex parameters for the ports on both ends of the connection.
• If a remote device does not autonegotiate, configure the duplex settings on the two ports to match.
The speed parameter can adjust itself even if the connected port does not autonegotiate.
Autonegotiation and Network Interface Cards
Problems sometimes occur between the switch module and third-party network interface cards (NICs).
By default, the switch module ports and interfaces are set to autonegotiate. It is common for devices like
laptops or other devices to be set to autonegotiate as well, yet sometimes autonegotation issues occur.
To troubleshoot autonegotiation problems, try manually setting both sides of the connection. If this does
not solve the problem, there could be a problem with the firmware or software on your NIC. You can
resolve this by upgrading the NIC driver to the latest version available from the manufacture.
Cabling Distance
If the port statistics show excessive FCS, late-collision, or alignment errors, verify that the cable distance
from the switch module to the connected device meets the recommended guidelines. See the
Adapter Specifications” section on page B-2 for cabling guidelines.
Resetting the Switch Module

For a standalone switch, you can perform these functions by using the AMM web interface:
• Reboot the switch
• Restore factory defaults
• Set or reset the IP address, netmask, and default gateway
• Enable or disable external ports

Chapter 3 Troubleshooting
• Enable or disable management through the external ports
• Change configuration
• Change or update firmware
For a switch stack, you can use the CLI to perform the same functions. For more information, see the
switch module software configuration guide and the command reference on Cisco.com.
Using the Mode Button to Reset the Switch Module
You can use the Mode button to reset a standalone switch module.
Caution For a standalone switch module, resetting the switch module deletes the configuration and reboots the
switch module.
For a standalone switch module, use a small pointed object to press and hold the Mode button on the
switch module front panel. The switch module LEDs begin blinking after about 3 seconds. Continue
holding down the Mode button. The LEDs stop blinking after 7 more seconds, and then the switch
module reboots.
How to Replace a Failed Stack Member
The switch module is now unconfigured. You can enter the switch module IP information by following
the procedures described in the switch module getting started guide on Cisco.com,
For switch stacks, pressing and holding the Mode button on a member switch module causes the stack
to reboot. It does not remove the configuration from any member switch.
How to Replace a Failed Stack Member
If you need to replace a failed stack member, you can hot swap or replace the switch module by following
this procedure (only Catalyst 3110 switch modules):
1. Get a replacement switch module that has the same model number as the failed switch module.
2. Disconnect and remove any modules and cable connections.
3. Remove the failed switch module.
4. Install and then connect the replacement switch module to the stack.
If you had manually set the member numbers for any members in the stack, you need to manually
assign the replacement switch module with the same member number as the failed switch module.
To manually assign the member number, see the switch module software configuration guide on
Cisco.com.
5. Make the same Gigabit Ethernet connections on the replacement switch module that were on the
failed switch module.
6. Reinstall any modules and cable connections.
The replacement switch module will have the same configuration for all the interfaces as the failed
switch module and will function the same as the failed switch module.
