Installing an EMM Module Cover in an Empty Bay
If your enclosure configuration calls for a single EMM, the empty EMM bay must contain a module
cover to ensure proper airflow.
Installing and Removing an EMM Module Cover
1 Align the edges of the module cover with the edges of the EMM bay (see Figure 3-6).
2 Push the module cover into the bay until it snaps into place.
3 To remove the module cover, pull out on the thin tabs on each end of the cover and slide the cover out
of the EMM bay.

Removing and Installing the Power Supply/Cooling Fan Module
Your enclosure supports two separate modules containing an integrated power supply and two cooling
fans. While the enclosure can operate temporarily with only one functional power supply, both cooling
modules (with two fans each) must be present for proper cooling. Three of the four fans must be
operational to avoid overheating of the enclosure.
NOTICE: A single power supply/cooling module can be removed from a powered-on enclosure for a maximum
period of 5 minutes. Beyond that time, the enclosure may automatically shut down to prevent damage.
