HotSwap Power Supply Replacement
Up to three power supplies (0 through 2), located across the bottom front of the server, can be
installed in the server without removing power.
To replace a power supply, perform the following steps:
CAUTION: Be careful when putting the power supply into the server. It is heavier than it
appears.
1. Grasp the handle in one hand and support the power supply with the other. Slide the power
supply into the server. The Power Supply LED should illuminate immediately.
2. Replace the T-15 mounting screw located to the right of the handle near the top of the power
supply.
The following graphic shows a front and rear view of a HotSwap Power Supply.
HotSwap Power Converter Fan Removal
The power to the server does not have to be off to remove or replace a HotSwap Power Converter
fan. Fans numbered 6 and 7 are located in the rear of the server.
To remove a fan from the server, perform the following steps:
NOTE: When one fan has failed (or is removed from the server), the system automatically puts
the remaining fan into high speed mode. The noise level of the server will increase.
1. There are four screws attached to each corner of each fan. Loosen only the captive Torx-head
screws located diagonally across the face of the fan (upper left, lower right sides).
2. Grasp the extended screw-heads (or the fan grill) and gently pull toward you. The fan
assembly will unplug from the electrical outlet and slide out of the server.
CAUTION: Running the server for extended periods of time with a cooling fan removed may
create hot spots inside the server and possibly shorten component life.
If the other fan fails when one fan is removed, the system will halt.
The following graphic shows where HotSwap Power Converter Fans are located.
