IBM Type 7977 manual Installing redundant power and cooling

Installing redundant power and cooling

You can install a second 835-watt hot-swap power supply. This upgrade option includes a hot-swap power supply, two hot-swap fans, a fan structure with an air duct and a single hot-swap fan, and a fan power cable. You must also purchase a second power cord to connect the power supply to the power source.

To install the redundant power and cooling option, complete the following steps:

1.Read the safety information that begins on page vii and the guidelines in “Handling static-sensitive devices” on page 9.

Attention: Static electricity that is released to internal server components when the server is powered-on might cause the server to halt, which might result in the loss of data. To avoid this potential problem, always use an electrostatic-discharge wrist strap or other grounding system when you work inside the server with the power on.

2.Turn off the server and peripheral devices, and disconnect the power cords and all external cables. Remove the left-side cover.

3.Remove all adapters.
