Guidelines
Guidelines for consideration when powering chassis on and off include.
• Remove the AC cord before inserting or removing a PSU.
• Move the PSU switch to the off position before connecting or disconnecting the AC power cord.
• Allow 15 seconds between powering off and powering on the PSU.
• Allow 15 seconds before powering on one PSU in the system, and powering off another PSU.
• Never power off a PSU while any amber LED is lit on the partner PSU.
• The chassis must be left in a power on state for 30 seconds following resumption from standby
before the chassis can be placed into standby again (applies to 5U84 only).
• Although the chassis supports standby, the expansion chassis shuts off completely during standby
and cannot receive a user command to power back on.
• An AC power cycle is the only method to return the 5U84 to full power from standby.

Powering On the 2U12 and/or 2U24 Expansion Chassis
NOTE:
Powering on the 2U12 and 2U24 expansion chassis is the identical process.

CAUTION:
Refer to Figure 94 and Figure 95 and verify that all expansion chassis and RAID chassis
power switches are in the off position (0) to ensure none of the chassis power on before needed.
