Each rack must have one control card, which is inserted into the rightmost slot of

the rack. The control card coordinates all rack functions, communicates with other

racks, and communicates with the management PC.

Before installing the control card, you must configure its battery jumper and

DIPswitches.

Figure 5-1. Control Card.

CAUTION

Cards are electrostatic-discharge (ESD) sensitive. To prevent ESD

damage, always wear grounding wrist straps when touching, removing,

or inserting cards. Store and transport cards in sealed, static-shielding

bags.

NOTE

Before installing the control card, the battery must be enabled.

Configuring the Battery Jumper

1. Locate the battery jumper pins, located above the battery and labeled JP1, on

the control card. (The control card normally ships with the battery disabled—

its jumper rests on only one of the pins, disabling the battery during storage

and transportation.)
