Reseating and Replacing Circuit Packs
Except for the CPU/Memory and Service CPs, power can be left on while a CP is reseated or replaced. When possible, CPs should not be removed when the amber LED is lighted.
Note: When a CP is removed from an unused slot (slot was being used for storage), a “Port Board Out of Service” error message is generated and the attendant Alarm LED flashes. The error message must be removed from the Error Log.
To remove a CP:
1.Remove cabinet front cover.
2.Make sure that your hands are clean and dry. Put on a wrist grounding strap and attach it to the metal grounding block on the back of the cabinet to discharge static electricity.
Caution: Static electricity can damage a CP.
3.With your thumb, pull up on the latch of the removal lever.
4.When the latch is up, pull the removal lever down until it stops, at an angle of about 30 degrees to the floor.
5.Pull the CP out a few inches, tugging hard; then slide the CP the rest of the way out of the carrier. Use both hands when removing a CP.
Danger: The backplane contains hazardous voltages. Do not touch the backplane during any maintenance procedure.
