Installing a power supply module

This procedure describes how to install power supply modules in the power supply cage. After you install the redundant power supply cage in the main unit, insert the two power supply modules.

Use this procedure also to replace faulty power supply modules. Redundant power supply modules can be exchanged while the system is running, as long as one of the modules remains active. This section is relevant only with the BCM400 main unit.

Note: When you upgrade to a redundant power supply, you must also install a redundant fan. Refer to “Installing a BCM400 cooling fan” on page 326.

Warning: Protect the hardware components against damage from electrostatic discharge. Always wear a grounded wrist strap before you handle components. Always place the components in a static-free container.

To install a power supply module

1Ensure you have the correct redundant power supply cage installed in the BCM400 main unit (see “Installing a redundant power supply cage (BCM400 only)” on page 288).

2Ensure that you position the power supply modules correctly before inserting them into the power supply cage. The green LEDs are located at the top right of the power supply modules.
