Powering Off An Ex8200 Switch - Juniper EX8208 Hardware Manual

Powering Off an EX8200 Switch

Before you power off the switch:
Ensure that you understand how to prevent electrostatic discharge damage. See
Electrostatic Discharge Damage" on page
Ensure that you do not need to forward traffic through the switch.
Ensure that you have the following parts and tools available to power off the switch:
An electrostatic discharge (ESD) grounding strap
An external management device such as a PC
A cable to connect the external management device to the console port (CON) or management port
(MGMT) on the primary Switch Fabric and Routing Engine (SRE) module in an EX8208 switch or on the
primary Routing Engine (RE) module in an EX8216 switch.
To power off a switch:
1. Connect a management device to the primary SRE module in an EX8208 switch or to the primary RE
module in an EX8216 switch. For connecting a management device to the console (CON) port, see
"Connect a Device to a Management Console Using an RJ-45 Connector" on page
a management device to the management (MGMT) port, see
Out-of-Band Management" on page
2. If the switch has two SRE or RE modules, shut down the backup SRE or RE module first. (If your switch
has only one SRE or RE module, skip to Step 2.) From the external management PC connected to the
primary SRE or RE module, issue the request system halt other-routing-engine operational mode CLI
command.
This command shuts down the backup SRE or RE module gracefully. A message displays on the console
confirming that the backup SRE/RE module has halted.
3. Shut down the primary SRE or RE module from the external management device by issuing the request
system halt operational mode CLI command. This command shuts down the switch gracefully and
preserves system state information. A message displays on the console confirming that the operating
system has halted.
You will see the following output (or something similar, depending on the hardware being shutdown)
after entering the command:
