Hot-swap a de-stage controller power module (DCPM) - AFF A700 and FAS9000
To hot-swap a de-stage controller power module (DCPM), which contains the NVRAM10
battery, you must locate the failed DCPM module, remove it from the chassis, and install
the replacement DCPM module.
You must have a replacement DCPM module in-hand before removing the failed module from the chassis and
it must be replaced within five minutes of removal. Once the DCPM module is removed from the chassis, there
is no shutdown protection for the controller module that owns the DCPM module, other than failover to the
other controller module.
Replacing the DCPM module
To replace the DCPM module in your system, you must remove the failed DCPM module from the system and
then replace it with a new DCPM module.
Steps
1. If you are not already grounded, properly ground yourself.
2. Remove the bezel on the front of the system and set it aside.
3. Locate the failed DCPM module in the front of the system by looking for the Attention LED on the module.
The LED will be steady amber if the module is faulty.
The DCPM module must be replaced in the chassis within five minutes of removal or the
associated controller will shut down.
4. Press the orange locking button on the module handle, and then slide the DCPM module out of the
chassis.
