NOTE Guidelines for consideration when power cycling:
l
Move the PCM power switch to the off position before connecting or disconnecting an AC or DC power cable.
l
Remove the AC or DC power cable before inserting or removing a PCM.
l
Allow 15 seconds between powering off and powering on the PCM.
l
Allow 15 seconds before powering on one PCM and powering off another PCM.
l
Powering off a PCM while any amber LED is lit on the partner PCM may result in complete loss of power to the
cabled enclosures, and a loss of access to data.
IMPORTANT See the topic about power cable requirements and the QuickSpecs for more information about power
cables used by MSA 1060/2060/2062 enclosures.
AC power supply
The AC Power and Cooling Module (PCM) is shown in the following figure. This PCM is supported by all MSA
1060/2060/2062 enclosures.

Connect AC power cord to AC PDU and AC PCM
Access the enclosure rear panel when making power cord connections.
1. Obtain a suitable AC power cord for each AC PCM that will connect to a power source.
2. Verify that the power switch on each redundant PCM is in the Off position.
3. Plug the power cord into the power cord connector on PCM (see figure above). Plug the other end of the power cord
into the rack power source, such as a PDU.
Repeat this sequence for the redundant AC PCM within the enclosure.
4. Repeat the procedure for the remaining AC
enclosures in the array.
