Power Off an ACX7100-48L Router


Before you power off an ACX7100-48L 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:

  1. Connect to the router using one of the following methods:
  2. 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.

    You see the following output (or something similar, depending on the hardware being shut down) after entering the command:

  3. 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.
  4. 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.

  5. 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.

  6. Uncable the router before removing it from the rack or cabinet.
