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.
Confirmed that the new, currently standalone switch is powered off.
Prepared an existing member for interconnecting with the new switch through
an uplink port by configuring an uplink port as a VCP on the existing member.
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 EZ Setup
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 ports as VCP interfaces.
NOTE: If you are using a nonprovisioned configuration, you may wish to 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 ports 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.
NOTE: If you are using a preprovisioned configuration, the member-id is assigned
to the member's serial number in the configuration file.
