Power Supply Removal and Replacement
*CAUTION*
Two AC Power Cords may be connected to this unit.
Power Supply Removal
To remove the PESA equipment item's power supply or power supplies take the
following steps:
1. Disconnect the AC power cord connected to the power supply to be
removed.
2. Remove or open the equipment item's front door.
3. Grasp the power supply slide lock and pull it toward the center of the supply.
4. Once the slide lock is slid toward the center of the supply, carefully pull the
power supply out of the equipment chassis.
5. Repeat step 1 and steps 3 and 4 to remove any additional power supplies
from the equipment item.
Power Supply Installation
To install the PESA equipment item's power supply or power supplies take the
following steps:
1. Align the primary power supply with the primary set of power supply circuit
card guides in the equipment item's chassis.
2. Carefully push the power supply into the chassis until the power supply
connector makes initial contact with the backplane power connector. At this
point, firmly but carefully continue pushing the power supply into the equip-
ment chassis while making sure the power connectors are properly aligned.
You may have to slide the power supply latch toward the center of the
supply in order for the latch to move past the frame's metal work. Continue
pushing the power supply until the power supply slide lock clicks into the
power supply slide lock hole provided in the equipment chassis and the
power connectors are firmly mated.
3. If additional power supplies are to be installed in the equipment chassis,
align them with a set of power supply circuit card guides in the equipment
item and repeat step 2.
