Adding A New Switch From A Different Wiring Closet To An Existing Virtual Chassis - Juniper EX4200 Hardware Manual

Adding a New Switch from a Different Wiring Closet to an Existing Virtual Chassis

This procedure can be used to add an EX4200 switch to an EX4200 Virtual Chassis from a different wiring
closet to an existing Virtual Chassis.
To add a new switch from a different wiring closet to an existing Virtual Chassis configuration, you must
use a long cable to connect the members switches across wiring closets. You can use any SFP, SFP+, or
XFP port and a fiber-optic cable for this purpose.
Before you begin, be sure you have:
Installed the uplink modules needed for the Virtual Chassis configuration. See
Module in an EX4200 Switch" on page
Mounted the new switch in a rack.
If the new member switch has been previously configured, reverted its configuration to the factory
defaults. See Reverting to the Default Factory Configuration for the EX Series Switch.
If you are expanding a preprovisioned configuration, made a note of the serial number (the number is
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
primary Virtual Chassis configuration file are applied to the new switch after it has been interconnected
with its uplink VCP to an 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 LCD Panel of
the standalone switch to specify temporary identification parameters. (When you interconnect the new
member switch with the existing Virtual Chassis configuration, the primary 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 one uplink module port as a VCP:
