Powering Off an ACX5000 Router
Before you power off an ACX5000 router:
• Ensure that you have taken the necessary precautions to prevent electrostatic discharge
(ESD) damage. See
Prevention of Electrostatic Discharge Damage .
•
Ensure that you do not need to forward traffic through the router.
Ensure that you have the following parts and tools available to power off the router:
•
An ESD grounding strap
•
An external management device such as a PC
• An RJ-45 to DB-9 rollover cable to connect the external management device to the
console port
To power off an ACX5000 router:
1.
Connect to the router using one of the following methods:
•
Connect a management device to the console (
CON
) port on an ACX5000 router.
For instructions about connecting a management device to the console (
CON
) port,
see “Connecting an ACX5000 Router to a Management Console” on page 121 .
•
You can shut down the ACX5000 router from a management device on your
out-of-band management network. For instructions about connecting a
management device to the management (
CO or C1 ) port, see “Connecting an
ACX5000 Router to a Network for Out-of-Band Management” on page 122 .
2.
Shut down Junos OS from the external management device by issuing the
