Installing AC Power Supplies
The E1200 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 E1200 chassis
contains six AC power supply slots, as shown in
Figure 7-1
.
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.
