Juniper XRE200 -, Hardware Manual

Page: 88 / 188

BEST PRACTICE: You should always access the EX8200 Virtual Chassis through the primary
XRE200 External Routing Engine. However, configuring the password ensures that you can
access the EX8200 member switch for purposes such as local monitoring or debugging.
3. Set each EX8200 switch as a Virtual Chassis member:
user@switch>
set chassis virtual-chassis
Follow the CLI prompts. You must reboot the switch to complete this procedure.
4. Upgrade the software on all switches and external Routing Engines in the Virtual Chassis to the same
Junos OS release. All switches and external Routing Engines must be running the same version of Junos
OS before being connected into a Virtual Chassis. See Installing Software on an EX Series Switch with a
Virtual Chassis or Single Routing Engine (CLI Procedure), Installing Software on an EX Series Switch with
Redundant Routing Engines (CLI Procedure), or Upgrading Software on an EX6200 or EX8200 Standalone
Switch Using Nonstop Software Upgrade (CLI Procedure).
5. Make a list of the serial numbers of all switches and external Routing Engines to be connected in the
Virtual Chassis configuration. For EX8208 switches, use the backplane serial number. For EX8216
switches, use the midplane serial number. See Locating the Serial Number on an EX8200 Switch or
Component and “Locating the Serial Number on an XRE200 External Routing Engine or Component”
on page 122 .
6. If both external Routing Engines are already powered on, skip this step.
Power on one of the external Routing Engines. The external Routing Engine with the most uptime is
assigned the primary role, so the external Routing Engine that is powered on in this step is the primary
external Routing Engine.
7. Log in to the primary external Routing Engine and specify the preprovisioned configuration mode. If
the external Routing Engine primary role has not been determined, log in to the external Routing Engine
that has been powered on the longest.
NOTE: You must use a preprovisioned configuration to configure an EX8200 Virtual Chassis.
Nonprovisioned configuration is not supported.
