Power Off an ACX7100-48L Router
Before you power off an ACX7100-48L 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
A Phillips number 2 screwdriver
To power off your ACX7100-48L router:
- Connect to the router using one of the following methods:
Connect a management device to the console (
CON) port on the router. For instructions about connecting a management device to the console (
CON) port, see Connect an ACX7100-48L Router to a Management Console.
You can shut down the router from a management device on your out-of-band management network. For instructions about connecting a management device to the management (
MGMT) port, see Connect an ACX7100-48L Router to a Network for Out-of-Band Management.
- Shut down Junos OS from the external management device
by issuing the request system halt operational mode CLI
command. This command shuts down the router gracefully and preserves
system state information. A message appears on the console, confirming
that the operating system has halted.
user@host> request system halt All nodes will halt, do you wish to continue ? [yes,no] (no) yes
You see the following output (or something similar, depending on the hardware being shut down) after entering the command:
System going down IMMEDIATELY *** System shutdown message from user@host *** halt the system at Tue Feb 16 16:40:55 2021
- Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end of the strap to the ESD point on the chassis.
Disconnect power to the router by performing one of the following tasks:
AC power supply—If the AC power source outlet has a power switch, set it to the off (
O) position. If the AC power source outlet does not have a power switch, gently pull out the power cord plug connected to the power source outlet.
DC power supply—Switch the circuit breaker on the panel board that services the DC circuit to the off position.
Remove the power source cable from the power supply faceplate:
AC power supply—Remove the power cord from the power supply faceplate by detaching the power cord retainer and gently pulling out the socket end of the power cord connected to the power supply faceplate.
DC power supply—Remove the screws securing the ring lugs attached to the power source cables to the power supply module (PSM) using the screwdriver, and remove the power source cables from the PSM. Replace the screws on the terminals and tighten them.
- Uncable the router before removing it from the rack or cabinet.
