Controller options
The server ships with an embedded SATA controller. For more information about the controller and its
features, see the
HP Smart Array Controllers for HP ProLiant Servers User Guide on the HP website
configure arrays, see the
Configuring Arrays on HP Smart Array Controllers Reference Guide on the HP
website
The server supports Smart Array controllers P420/1 GB FBWC, P420/2 GB FBWC, and P222/512 MB
FBWC. FBWC upgrade options are also available. FBWC consists of a cache module and a capacitor pack.
The DDR cache module buffers and stores data being written by the controller. When the system is powered
on, the capacitor pack charges fully in about 5 minutes. In the event of a system power failure, a fully
charged capacitor pack provides power for up to 80 seconds. During that interval, the controller transfers the
cached data from DDR memory to flash memory, where the data remains indefinitely or until a controller
retrieves the data.
CAUTION: The cache module connector does not use the industry standard DDR3 mini DIMM
pinout. Do not use this controller with cache modules designed for other controller models,
because the controller can malfunction and you can lose data. Also, do not transfer this cache
module to an unsupported controller model, because you can lose data.
CAUTION: After the server is powered down, wait 15 seconds and then check the amber LED
before unplugging the cable from the cache module. If the amber LED blinks after 15 seconds, do
not remove the cable from the cache module. The cache module is backing up data, and data is
lost if the cable is detached.

CAUTION: The cache module connector does not use the industry standard DDR3 mini DIMM
pinout. Do not use this controller with cache modules designed for other controller models,
because the controller can malfunction and you can lose data. Also, do not transfer this cache
module to an unsupported controller model, because you can lose data.
To install the component:
1.
Back up all data.
2.
Close all applications.
CAUTION: In systems that use external data storage, be sure that the server is the first unit to be
powered down and the last to be powered back up. Taking this precaution ensures that the system
does not erroneously mark the drives as failed when the server is powered up.
3.
If installed, remove the rack bezel (on page 59 ).
4.
Power down the server (on page 17 ).
5.
Remove all power:
a.
Disconnect each power cord from the power source.
b.
Disconnect each power cord from the server.
6.
Extend the server from the rack (on page 17 ).
7.
Remove the access panel (on page 19 ).
