■ If you are expanding a preprovisioned configuration, made a note of the serial
number (on the back of the switch). You will need to edit the Virtual Chassis
configuration to include the serial number of the new member switch.
■ If you are expanding a preprovisioned configuration, edited the existing Virtual
Chassis configuration to include the serial number of the new member switch.
You can specify the role of the new member switch when you add its serial
number in the Virtual Chassis configuration file. The parameters specified in the
master Virtual Chassis configuration file are applied after the new member switch
has been interconnected with its uplink VCP to an existing member switch.
■ Confirmed that the new, currently standalone switch is powered off.
■ Prepared an existing member switch for interconnecting with the new switch
through an uplink module port by configuring an uplink module port as a VCP
on the existing member switch.
NOTE: After you have created a preprovisioned Virtual Chassis configuration, you
can use the autoprovisioning feature to add member switches to that configuration.
To add a new member switch that is going to be interconnected with the existing
Virtual Chassis configuration across wiring closets:
1. Power on the new switch.
2. Connect a laptop or terminal to the console port of the switch, or use EZSetup
on the standalone switch to specify temporary identification parameters. (When
you interconnect the new member switch with the existing Virtual Chassis
configuration, the master will overwrite and disable any specified parameters
that conflict with the Virtual Chassis parameters or assigned member
configuration.)
3. Use the CLI or the J-Web interface to set the uplink module ports as VCPs.
NOTE: If you are using a nonprovisioned configuration, you might configure the new
member switch with a mastership priority value that is less than that of the existing
member switches. Doing so ensures that the new member switch will function in a
linecard role when it is included within the Virtual Chassis configuration.
4. Power off the new switch.
5. Interconnect the new member switch to at least one member of the existing
Virtual Chassis configuration using the uplink module ports on each of the
switches that have been configured as VCPs.
6. Power on the new member switch.
7. Confirm that the new member switch is now included within the Virtual Chassis
configuration by checking the front-panel display for the member ID. It should
display a member ID that is higher than 0 (1 through 9), because there is already
at least one member of the Virtual Chassis configuration.
