Removing an ACM

Removing an ACM


Remove an advanced clock module (ACM) if it has failed.



Before removing an ACM, determine whether the ACM to be removed is active or standby, and ensure that the power indicator of the other ACM is steady on.

  • After you remove the active ACM, wait for 6 seconds until the power indicator of the standby ACM changes from steady on to blinking for about 1 minute. Then wait until the power indicator of the standby ACM changes from blinking to steady on before performing follow-up operations.
  • After you remove the standby ACM, wait for 2 seconds before performing follow-up operations.


No data preparation is required for this operation.


  • ESD gloves
  • Packaging materials, for example, an ESD bag


  1. Hold down the plastic latch on the inner side of the ACM handle. See step (1) in Figure 6-23.
  2. Gently remove the ACM by holding its handle. See step (2) in Figure 6-23.
  3. Place the removed ACM in an ESD bag.
