Chapter 7 Installing AC Power Supplies

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 Figure 11.

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.
