E Battery Operation
The HP TopTools Remote Control card includes a rechargeable Nickel
Metal-Hydride (NiMH) battery pack that ensures a supply of power to the card
components.
This battery pack contains four cells and is rated at 4.8V at 1100mAH. In case of
a loss of AC power to the server, or a power supply failure, the battery continues
to power the HP TopTools Remote Control for up to one hour. The battery pack,
which is attached to the card with two plastic darts, is designed for easy removal
and replacement by the customer.
NOTE HP TopTools Remote Control can continue to perform its
functions with a non-operating battery as long as power is
being supplied to the server or power is being applied by the
optional external AC/DC adapter.
Safety
To reduce the possibility of an electric shock from the local area network, plug
the computer into an AC outlet before connecting to the network. Likewise,
disconnect the network before unplugging the computer from the AC power
outlet.
Shutting Down the Card to Conserve Battery Power
In the event that the server must be turned off for an extended period of time and
no external AC/DC adapter is connected, the HP TopTools Remote Control card
should also be shut down. This prevents battery pack discharge while the server
is not in service.
The HP TopTools Remote Control card automatically powers on when AC power
is applied to the server.
Charging
To ensure battery power, the HP TopTools Remote Control card provides two
sources for battery charging. The on-board battery is charged:
• Through the host server’s PCI bus when the host server is powered on, or
• When the card’s optional external AC/DC adapter is connected.
