PRO SWITCHING SYSTEM
5.1.2 C ONFIGURE THE C ONTROL C ARD AND DIP S WITCHES
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
DIP switches.
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.)
