4. Power-on the switch (see "Providing power to the switch" on page 20).
Note: Power is supplied to the switch as soon as the first power supply is
connected and turned on.
5. Verify that all components are functioning correctly by checking their LEDs. If
the LEDs do not indicate correct operation, try reinstalling the corresponding
component.
Verifying the correct operation of the system
1. Log in to the switch as admin.
2. Verify that the switch is functioning correctly by entering the switchShow or
switchStatusShow commands. The switchShow command displays switch and
port status information.
3. Verify that all the IP address information is correct by entering ipAddrShow
and checking the results against the IP information recorded in the
"config-miscinfo.txt" file.
Reconnecting the system to the network and fabric
1. Install the SFPs and reconnect the cables to the switch.
2. Organize the cables as required.
Attention: Do not route cables in front of the air exhaust vent (located on the
upper portion of the port side of the chassis).
Verifying the correct configuration of the fabric
Copying the command outputs from this section into a file is recommended.
1. Create an "after" SAN profile by entering the following commands and copying
the output to a text file named "SANafter.txt":
v nsShow
v nsAllShow
v switchShow
v fabricShow
2. Determine any differences between the information in the "SANafter.txt"file and
the information in the "SANbefor.txt" file created earlier. In particular, look for
differences in the following:
v Device types
v Number of devices
v ISL and port states
v Number of switches in the fabric
3. Resolve any issues or unintentional changes to the switch or fabric.
v If there are any mechanical problems, try reseating the associated component.
v If the configuration information is not correct for the switch, modify as
required. If necessary, the configuration saved before the replacement can be
downloaded using the configDownload command. The configDownload
command can be entered through a Telnet or serial session, but the switch
must have an Ethernet connection to the server name or IP of the host for
the download process to complete. For more information, refer to the help
configdownload command or the Fabric OS Command Reference.
v If other issues exist, contact IBM support.
