Adding a New Switch to an Existing EX4200 Virtual Chassis Within the Same Wiring Closet
Copyright © 2010, Juniper Networks, Inc.
To add a switch to an existing EX4200 Virtual Chassis configuration, use the procedure
that matches what you need to accomplish:
Adding a New Switch to an Existing EX4200 Virtual Chassis Within the Same Wiring
Closet on page 987
Adding a New Switch from a Different Wiring Closet to an Existing EX4200 Virtual
Chassis on page 988
Adding a New Switch to an Existing Preprovisioned EX4200 Virtual Chassis Using
Autoprovisioning on page 989
Before you begin, be sure you have:
Mounted the new switch in a rack.
Confirmed that the new switch is powered off.
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 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 to an existing EX4200 Virtual Chassis configuration within
the same wiring closet:
If the new member switch has been previously configured, revert that switch's
1.
configuration to the factory defaults. See "Reverting to the Default Factory
Configuration for the EX Series Switch" on page 415.
Interconnect the unpowered new switch to at least one member of the existing Virtual
2.
Chassis configuration using the dedicated Virtual Chassis ports (VCPs).
Power on the new switch.
3.
Confirm that the new member switch is now included within the Virtual Chassis
4.
configuration by checking the front-panel LCD 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.
