Installing and Maintaining the E1200i System

35

The E1200i AC system requires a minimum of two AC power supplies to operate, three for power 
redundancy, four for facility redundancy (2+2), and 6 for 3+3 redundancy. To comply with safety agency 
and EMI regulations, you must install the AC-cord retainer over all power cords. The E1200i AC chassis 
contains six AC power supply slots, as shown in 

.

Note: If you are installing only two power supplies, they must be installed in the same row. FTOS 
will generate an error message if the two power supplies are not in the same row.

Note: If you are installing power supplies for redundancy:

•

For 2+2 redundancy, two power supplies must reside in each row. That is, two in the top row and two in the 
bottom row.

•

For redundant operation with only three power supplies, install all three power supplies in the same row.

Note: The On/Standby switch disconnects power to the rest of the chassis from all 6 AC power 
supplies.

•

When the AC cord is attached, power supply fans will spin and the LEDs will indicate status while the On/
Standby switch is in Standby.
