membership.
– VLAN Trunking Protocol (VTP) pruning for reducing network traffic by
restricting flooded traffic to links destined for stations receiving the traffic.

between two devices and for negotiating the type of trunking
encapsulation (802.1Q) to be used.
– Voice VLAN for creating subnets for voice traffic from Cisco IP phones
– VLAN 1 minimization to reduce the risk of spanning-tree loops or storms
by enabling VLAN 1 to be disabled on any individual VLAN trunk link.
With this feature enabled, no user traffic is sent or received. The switch
CPU continues to send and receive control protocol frames.

OK: This green LED is on the left side of the information panel, above the four
external 10/100/1000 Mbps connectors. When this LED is lit, it indicates that
the Gigabit Ethernet switch module has passed the power-on self-test (POST)
with no critical faults and is operational.
Gigabit Ethernet switch module error (fault): This amber LED is on the right
side of the information panel, above the four external 10/100/1000 Mbps
connectors. When this LED is lit, it indicates that the Gigabit Ethernet switch
module has a fault. If the Gigabit Ethernet switch module fails the POST or
detects an operational fault, this LED is lit.
Note: When this LED is lit, the system-error LED on the BladeCenter unit is
also lit.
Ethernet link OK: This green link status LED is at the top of each external
10/100/1000 Mbps connector. When this LED is lit on a port, it indicates that
there is a connection (or link) to a device on that connector.
Ethernet Tx/Rx: This green activity LED is at the bottom of each external
10/100/1000 Mbps connector. When this LED flashes on a connector, it
indicates that data is being transmitted or received (that is, activity is

occurring) between that port and another device on the network link. The
flashing frequency is proportional to the amount of traffic on the network link.
External connections
The switch-module external connections include
v Four external 1000BASE-T Ethernet connectors for connecting to external
Ethernet devices, such as backbones, end stations, and servers. These
connectors are identified as ports 17, 18, 19, and 20 in the switch
configuration menus and are labeled 17 through 20 (from top to bottom) on
the Gigabit Ethernet switch module.
v Serial port RS-232 connector for local console port connections.
12 Cisco Systems Intelligent Gigabit Ethernet Switch Module: Installation Guide
Chapter 2. Installing and removing a Gigabit Ethernet
switch module
Attention: To maintain proper system cooling, each I/O-module bay must
contain either a module or a filler module; each blade bay must contain either
a blade or a filler blade.
The BladeCenter unit supports one hot-plug Gigabit Ethernet switch module,
in I/O-module bay 1. The Gigabit Ethernet switch modules in I/O-module
bays 1 and 2 are for the integrated Ethernet controllers or Fibre Channel
expansion modules in the blade servers. You might want to install Gigabit
Ethernet switch modules in other I/O-module bays of the BladeCenter unit
when additional Ethernet or fiber controllers are installed or activated.
For additional information about the location of the Gigabit Ethernet switch
module, the network interface requirements, and expansion options, see the
documentation that came with the BladeCenter unit.
Installation guidelines
Before you begin to install the Gigabit Ethernet switch module in the
BladeCenter unit, read the following information:
v Read the safety information beginning on page v and the guidelines in
“Handling static-sensitive devices” on page 14, and read the safety
statements in the BladeCenter unit documents.
v Orange on the release latch on the Gigabit Ethernet switch module indicates
that the device can be hot-swapped, which means that you can install or
remove this component while the BladeCenter unit is on. See the instructions
in this chapter for more information about installing or removing hot-swap
or hot-plug components.
v You do not have to turn off the BladeCenter unit to install or replace any of
the hot-swap modules on the rear of the unit.
v If you plan to install a Gigabit Ethernet switch module in I/O-module bay 3
or 4 of the BladeCenter unit, you must also install an I/O expansion card in
the blade server to support the Gigabit Ethernet switch modules in these
bays.

System reliability considerations
To help ensure proper cooling and system reliability, make sure that:
v Each of the I/O-module bays on the rear of the BladeCenter unit has either a
module or a filler module installed.
v A removed hot-swap module or blade server is replaced with another
module or filler module within 1 minute of removal.
Handling static-sensitive devices
Attention: Static electricity can damage electronic devices. To avoid damage,
keep static-sensitive devices in their static-protective packages until you are
ready to install them.
To reduce the possibility of electrostatic discharge, observe the following
precautions:
v Limit your movement. Movement can cause static electricity to build up
around you.
v Handle the device carefully, holding it by its edges or its frame.
v Do not touch solder joints, pins, or exposed printed circuitry.
v Do not leave the device where others can handle and damage it.
v While the device is still in its static-protective package, touch it to any
unpainted metal surface of the BladeCenter unit or any unpainted metal
surface on any other grounded rack component for at least 2 seconds. (This
drains static electricity from the package and from your body.)
v Remove the device from its package and install it directly into the
BladeCenter unit without setting it down. If it is necessary to set down the
device, put it back into its static-protective package. Do not place the device
on the BladeCenter unit or on a metal surface.
v Take additional care when handling devices during cold weather. Heating
reduces indoor humidity and increases static electricity.
Installing a Gigabit Ethernet switch module
To install a Gigabit Ethernet switch module, complete the following steps:
1. Read the safety information beginning on page v and “Installation
guidelines” on page 13.
2. Remove the acoustic attenuation module, if one is installed, from the rear
of the BladeCenter unit. For more information, see the documentation that
came with the BladeCenter unit.
3. Select an I/O-module bay in which to install the Gigabit Ethernet switch
module.

Note: For details about I/O-module bay requirements, see the
BladeCenter documents that came with your BladeCenter unit.
4. Remove the filler module from the selected bay. Store the filler module for
future use.
5. If you have not already done so, touch the static-protective package that
contains the Gigabit Ethernet switch module to any unpainted metal
surface of the BladeCenter unit or any unpainted metal surface on any
other grounded rack-component for at least 2 seconds.
6. Remove the Gigabit Ethernet switch module from its static-protective
package.
7. Make sure that the release latch on the Gigabit Ethernet switch module is
in the open position (perpendicular to the module).
8. Slide the Gigabit Ethernet switch module into the applicable I/O-module
bay until it stops.

9. Push the release latch on the front of the Gigabit Ethernet switch module
to the closed position. After you insert and lock the Gigabit Ethernet
switch module, it is turned on, and the power-on self-test (POST) runs to
verify that the Gigabit Ethernet switch module is operating correctly. The
POST results are displayed by the status LEDs.
10. Make sure that the LEDs on the Gigabit Ethernet switch module indicate
that it is operating correctly. Make sure that the OK LED on each Gigabit
Ethernet switch module is lit. See “LEDs” on page 11 for a description of
the operation of these LEDs.
