Creating an Ethernet connection
Perform the following steps to create an Ethernet connection to the switch.
1. Remove the plug from the Ethernet port.
2. Connect an Ethernet cable to the switch Ethernet port and to the workstation or to an Ethernet
network containing the workstation.
NOTE
At this point, the switch can be accessed remotely, by command line or by Web Tools. Ensure that
the switch is not being modified from any other connections during the remaining tasks. The Ethernet
management port also supports AutoMDI/MDIX.
Setting the domain ID of the switch
Perform the following steps to set the switch domain ID.
1. Log in to the switch through Telnet using the admin account.
2. Modify the domain ID if required.
The default domain ID is 1. If the switch is not powered on until after it is connected to the fabric and
the default domain ID is already in use, the domain ID for the new switch is automatically reset to a
unique value. If the switch is connected to the fabric after it has been powered on and the default
domain ID is already in use, the fabric segments. To find the domain IDs that are currently in use,
enter the fabricShow command on another Extension Switch in the fabric.
Perform the following steps to modify the Domain ID.
a) Disable the switch by entering the switchDisable command.
b) Enter the configure command. The command prompts display sequentially; enter a new
value or press Enter to accept each default value.
c) Enter y after the "Fabric param" prompt.
Fabric param (yes, y, no, n): [no] y
d) Enter a unique domain ID (such as the domain ID used by the previous Extension Switch, if
still available).
Domain: (1..239) [1] 3
e) Complete the remaining prompts or press Ctrl+D to accept the remaining settings without
completing all the prompts.
f) Re-enable the switch by entering the switchEnable command.
Setting the date and time of the switch
The date and time switch settings are used for logging events. Switch operation does not depend on the
date and time; a switch with incorrect date or time values still functions properly.
You can synchronize the local time of the principal or primary fabric configuration server (FCS) switch to
that of an external Network Time Protocol (NTP) server.
Perform the following steps to set the date and time of a switch.
1. Log in to the switch as admin.
2. Enter the date command at the command line using the following syntax:
date ["newdate"]
