Environmental Monitoring Unit (EMU)

UltraSCSI RAID Enclosure 3–27

Replacing an EMU

To remove an EMU complete the procedure in Table 3–8. To install an
EMU complete the procedure in Table 3–9.

Table 3–8 Removing an EMU

1. Shut down the system by clearing the cache module and shutting down the controller.

2. Turn Off the enclosure power.

3. Pull the extractor latches forward and remove the EMU.

CXO-5497A-MC

Table 3–9 Installing an EMU

1. Remove the EMU from the shipping container and ensure that it is a model DS–BA35X–EB.
