Preparing for Power Failure

To prepare for power failures, regularly monitor power supplies and batteries.

Monitoring Power Supplies

Monitor power-generating equipment and run regular checks on any backup

generators to make sure that you can handle extended power outages.

Maintaining Batteries

Make sure that the batteries in each enclosure and all spare batteries are always fully

charged. Correct any problems that are causing the batteries to become drained.

Recharging Spare Batteries

Spare batteries require recharging every six months.

Monitoring Batteries

To check the state of a battery in a system enclosure using OSM:

1. Log on to the OSM Service Connection.

2. In the tree pane, select the battery you want to check.

3. On the Attributes tab under Logical attributes, check that the Enabled State is

Enabled and that the Charged State is Fully Charged.

To check the state of a battery in a system enclosure using TSM:

1. Log on to the TSM Service Application.

2. In the tree pane, select the battery you want to check.

3. On the Attributes tab of the details pane, check that the Battery State shows

Enabled.

For more information on battery attributes and actions, see the OSM Service

Connection online help or the TSM Service Application online help.
