Hot swapping a DC Combiner Module

Caution You can hot swap a DC combiner module without powering down the FortiGate-7121F as long as three FortiGate-7121F PSUs remain connected to power and operating normally. If you need to hot swap a DC combiner module connected to one of three operating PSUs, you must power down the FortiGate-7121F chassis first.
  1. Attach an ESD wrist strap to your wrist and to an ESD socket or to a bare metal surface on the chassis or frame.

  2. Disconnect the DC power input cable on the front of the DC combiner module that connects the DC combiner module to the FortiGate-7121F PSU.

  3. Remove the DC combiner module latch locking screw.

  4. Press down on the DC combiner module latch and use the handle to pull the module out of the chassis.

  5. Insert a replacement module into the empty slot and tighten the DC combiner module latch locking screw.

  6. Reconnect the DC power input cable to the DC combiner module.
