Installing or removing the ThinkServer RAID 700 Battery
This topic provides instructions on how to install or remove the ThinkServer RAID 700 Battery (hereinafter
referred to as the TR 700 Battery) if your server has a ThinkServer RAID 700 Adapter installed.
The TR 700 Battery protects the integrity of the cached data on the ThinkServer RAID 700 Adapter by
providing backup power up to 72 hours in the case of a complete ac power failure or a brief power outage.
It has built-in functionality to automatically charge the battery pack and to communicate battery status
information (such as voltage, temperature, and current) to your server. It also provides an inexpensive
alternative to using an uninterruptible power supply, and a second level of fault tolerance when used with an
uninterruptible power supply.
The temperature of the TR 700 Battery is generally 15-20°C (59-68°F) higher than the ambient temperature
during fast charge. Therefore, to complete a recharge cycle, the ambient temperature should be lower
than 55°C (131°F). If the ambient temperature exceeds 55°C (131°F), the recharge cycle will terminate
prematurely, thus preventing the TR 700 Battery from reaching a fully charged state. A recharge cycle lasts
at least six hours under normal operating conditions.
Attention: It is recommended that you replace the TR 700 Battery annually or after 500 recharging cycles,
whichever comes first.
Installing the TR 700 Battery
Attention: Do not open your server or attempt any repair before reading and understanding “Safety information”
on page iii and “Guidelines” on page 65.
