7.Return enclosure to fully home position and attach to rack using captive fasteners on front flanges.
Note: Rack rails have features to restrict complete enclosure withdrawal while still allowing access to the cooling fans. If it becomes necessary to completely remove the system, pull the enclosure out until it stops then rotate the latches, shown in Figure 15 (right hand up, left hand down), to completely remove the enclosure from the rack.
Power cord connection
CAUTION:
The power connection must always be disconnected prior to removal of a PSU from the enclosure.
To connect the power cord, do the following:
1.Observe all safety and ESD precautions listed in the Safety and Warranty Guide.
2.Attach a power cord for the installed PSU. The Power On LED (see 1 in Figure 16) for the PSU will blink green when AC main power is present. The Power On LED will illuminate a constant green when power to the PSU is turned on.

Grounding checks
The SMC - Storage Array must only be connected to a power source that has a safety electrical earth connection.
CAUTION:
If more than one enclosure is installed in a rack, the earth connection to the rack is even more important, because the rack will have a high “earth leakage current” (“touch current”).
Before powering on, the earth connection to the rack must be checked by an electrical engineer who is qualified in local and National electrical standards.
