The BladeCenter Chassis Manager interface appears.
Step 3 Expand I/O Module Tasks in the left-hand navigation tree.
Step 4 Select Management under I/O Module Tasks in the left pane.
An I/O Module Management heading appears in the display.
Step 5 Click the link of the physical slot that holds the Server Switch Module that you want to configure.
A heading appears, where X is the number of the slot.
Step 6 Enter an IP address for the Server Switch Module in the IP address field of the New Static IP
Configuration section.

Note The IP address of the Server Switch Module must fall in the same subnet as the modules in the
other slots.
Step 7 Enter a subnet mask or the Server Switch Module in the Subnet mask field of the New Static IP
Configuration section.
Note The subnet mask of the ServerSwitch Module must match the subnet mask of the modules in the
other slots.
Step 8 Enter a gatewayIP address for the Server Switch Module in the Gateway address field of the New Static
IP Configuration section, and then click Save.
Note The gateway address of the Server Switch Module must match the gateway address of the
modules in the other slots.

Chapter 2 Installing and Configuring the Server Switch
Step 9 Open a Telnet session to the Server Switch Module with the IP address that you configured in Step 6.
Log in to your Server Switch Module, and then proceed to “Changing the Default Password” to secure
your Server Switch Module. Log in with the default user name of USERID and password of
PASSW0RD, where the 0 in PASSW0RD is a zero.

Changing the Default Password
Change the default password immediately to secure your Server Switch. To change the default
administrative password, follow these steps:
Configuring the Server Switch Module
Step 1 Switch to Privileged Exec mode by entering the
Cisco BladeCenterH> enable
Cisco BladeCenterH#Switch to Global Configuration mode by entering the
command.
Cisco BladeCenterH# configure terminal
Cisco BladeCenterH(config)#
Step 2 Change the password of the user ID by entering the
• User ID for which you need to change the password (in this case, USERID)
•
password
• New password that you want to apply to the user ID
Cisco BladeCenterH(config)# username USERID password n0accE$$
Step 3 Return to User Exec mode by entering the

Configureyour system clock immediately so that all system messages include accurate timestamps. You
can either configure the clock setting on the onboard Server Switch clock, or you can synchronize your
Server Switch to a network time protocol (NTP) server.
To configure the clock settings on the onboard clock, follow these steps:
Step 1 Switch to Privileged Exec mode by entering the
Cisco BladeCenterH> enable
Cisco BladeCenterH#

Configuring the Server Switch Module
Step 2 Set the on-board clock by entering the clock set command with the following variables:
• the time of day in hh:mm:ss format
• the day in dd format
• the month in mm format
• the year in yy format
The example that follows sets the date to 1:45 am on June 3rd, 2004:
Cisco BladeCenterH# clock set 01:45:00 03 06 04
To configure primary, secondary, and tertiary NTP servers to synchronize the Server Switch with the
network, follow these steps:

Chapter 2 Installing and Configuring the Server Switch
Connecting Beyond BladeCenter
To extend your InfiniBand fabric beyond your BladeCenter cluster, you must configure the priority of
the subnet manager on your Server Switch Module, then connect one or more of the external interfaces
on your Server Switch Module to an outside InfiniBand fabric.
The device with the highest subnet manager priority becomes the master subnet manager in the
InfiniBand network. To configure subnet manager priority, follow these steps:
Connecting Beyond BladeCenter
Step 1 Switch to Privileged Exec mode by entering the
Cisco BladeCenterH> enable
Cisco BladeCenterH#
Step 2 Switch to Global Configuration mode by entering the
Cisco BladeCenterH# configure
Cisco BladeCenterH(config)#
Step 3 Configure the priority of the subnet manager by entering the
•
subnet-prefix
• Subnet prefix of the InfiniBand network to which the Server Switch belongs
•
priority
• Priority integer value of the subnet manager (1 is the lowest the priority)
Cisco BladeCenterH(config)# ib sm subnet-prefix fe:80:00:00:00:00:00:00 priority 1
Step 4 Exit Global Configuration mode.
Cisco BladeCenterH(config)#exit

command with this information:
After you configure your subnet manager priority, connect your Server Switch Module to the outside
InfiniBandfabric. By default, the external interfaces on your Server Switch Module auto-negotiatespeed
with the fabric.
Connecting InfiniBand Cables
To plug in an InfiniBand cable, push the connector into the interface until you hear/feel a click.
To remove a cable with a pull connector, grasp the connector with one hand and push it toward the port,
then pull the latch away from the port with your other hand and gently wiggle the connector away from
the port.
