Dell EqualLogic PS-M4110 Hardware Owner's Manual Chapter Identifying Control Module Failures
Figure 25: Location of Control Modules
To remove a control module from a PS-M4110 blade storage array:
1. Open the array drawer to expose the control modules. See Opening the Array Drawer on page 12.
2. Push down on the control module's release button (shown in callout 1 of Figure 26). The control module's
release latch will spring open partway to release the control module from the slot.
3. Hold down the release button and swing the control module's release latch to its fully open position (callout 2
of Figure 26). This begins to eject the control module from the array. The control module rises enough out of
its slot for you to grip it with your hands.
4. Remove the control module. Grip it by its sides and pull it up and out of its slot (callout 3 of Figure 26) until
it is completely free.
Caution: Do not pull the control module by its release latch. This could damage the latch.
