Replacing or upgrading a power supply

The BCM200 uses a standard power supply. The BCM400 and expansion units use either a standard or redundant power supply.

This chapter describes the following power supply installation and replacement techniques:

•“Replacing a standard power supply” on page 275

•“Upgrading to a redundant power supply” on page 286

Note: For the BCM400 RFO configuration only, a redundant power supply is included. Use a redundant fan with the redundant power supply (see “Installing a BCM400 cooling fan” on page 326).

Warning: You must remove all of the connections to the BCM system before you power the system down. Failure to disconnect the lines before you power down the system can cause damage to the system.

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.

Replacing a standard power supply

This section describes how to remove and install a standard power supply in the main unit and contains the following procedures:

•“Removing a BCM200 power supply” on page 276

•“Installing a BCM200 standard power supply” on page 278

•“Removing a BCM400 standard power supply” on page 282

•“Installing a BCM400 standard power supply” on page 284

If the main unit or expansion unit has a standard power supply that fails, then all activity on the system stops. This procedure describes how to replace a failed standard power supply unit. Figure 133 provides an overview of the process for replacing a standard power supply.
