Installing a redundant power supply cage (BCM400 only)
This procedure describes how to install a redundant power supply cage in the BCM400 main unit.
After you install the redundant power supply cage in the main unit, install the two power supply
modules (see
“Installing a power supply module” on page 303 ).
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.
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 334 .
