Adding or Replacing a Member Switch or an External Routing Engine in an EX8200 Virtual Chassis (CLI Procedure)

You can configure an EX8200 Virtual Chassis to include two EX8200 switches and one or two XRE200 External Routing Engines. You can add or replace a member switch or an external Routing Engine if one needs to be replaced for any reason.

To add or replace a member switch or external Routing Engine in an EX8200 Virtual Chassis:

1. If you are replacing an existing switch or external Routing Engine, power off the device. See Powering Off an EX8200 Switch or Powering Off an XRE200 External Routing Engine.
2. Uncable the device that you will remove from the Virtual Chassis.
3. Upgrade the software on the new switch or external Routing Engine to the Junos OS release currently running in the Virtual Chassis, unless the switch or external Routing Engine is already running that release. See Installing Software on an EX Series Switch with a Single Routing Engine (CLI Procedure) or Installing Software on an EX8200 Switch with Redundant Routing Engines (CLI Procedure).
4. Note and record the serial number of the new switch or external Routing Engine. See Locating the Serial Number on an EX8200 Switch or Component and Locating the Serial Number on an XRE200 External Routing Engine or Component.
5. Log onto the master external Routing Engine on the Virtual Chassis.
6. Delete the device that you uncabled from the Virtual Chassis configuration:
   [edit virtual-chassis]
user@external-routing-engine# delete member member-id serial-number serial-number role role

   For example:

   • To delete a switch from the Virtual Chassis configuration:
     [edit virtual-chassis]
user@external-routing-engine# delete member 1 serial-number abc123 role line-card

   • To delete an external Routing Engine from the Virtual Chassis configuration:
     [edit virtual-chassis]
user@external-routing-engine# delete member 8 serial-number yza567 role routing-engine

7. Add the new device to the Virtual Chassis configuration:
   [edit virtual-chassis]
user@external-routing-engine# set member member-id serial-number serial-number role role

   For example:

   • To add a switch to the Virtual Chassis configuration:
     [edit virtual-chassis]
user@external-routing-engine# set member 1 serial-number lmn910 role line-card

   • To add an external Routing Engine to the Virtual Chassis configuration:
     [edit virtual-chassis]
user@external-routing-engine# set member 8 serial-number opq112 role routing-engine

8. Commit the configuration:
   [edit]
user@external-routing-engine# commit synchronize

9. Connect the new device to the EX8200 Virtual Chassis. See Connecting an EX8200 Switch to an XRE200 External Routing Engine.
