Installing and Maintaining BN Platforms
5-18 109352-E Rev. A
6. Replace the EMC shield and front bezel. (Refer to Chapter 4, “Accessing
the Interior,” for instructions.)
Replacing a Power Module
The BLN-2 supports two and the BCN supports four 620-watt power modules that
are hot-swappable. You can easily access these power modules from the back of
the hardware platform.
Each power module provides up to
90 amperes (A) @ +5 volts (V)
10 A @ +12 V
1 A @ -12 V
4 A @ +12 V (fans)
The Gate Access Management Entity (GAME) operating system generates an
event message in response to any change in the status of each power module.
These messages identify the power module by its slot. When looking at the rear of
the BLN-2, the power module slots number 1 and 2 from left to right. The BCN
power module slots number 1 through 4 from bottom to top.
Each power module has a green Power OK LED. When on, this LED indicates the
power module is operational and receiving current.
When you insert an operational power module into the BLN-2 or BCN, the Power
OK LED turns on. At the same time, the hardware platform automatically
redistributes the load among all power modules.
When you power on either the BLN-2 or BCN, and the hardware platform
provides sufficient power for redundancy, you can remove an operational power
module without affecting the operation of the hardware platform. When you
remove a power module, the Power OK LED on the front panel turns off, and the
hardware platform automatically redistributes the load among the remaining
power modules.
