Original — December 1991 UM4.6:CS6003
2.2.2.1 AC Power Cord
The ac power cord is stored with the operator station cables and
umbilical cables in the pocket on the inside of the calibrator front panel
cover. The ac power cord plugs into the receptacle on the calibrator front
panel. The ac power cords on calibrators that operate on 100 volt or 240
volt ac power have no male connector. The user supplies a connector
that matches local outlets. On these cords, the green wire is the safety
ground wire.
2.2.2.2 Wrist Strap
The wrist strap helps prevent static discharges that could seriously
damage cards being handled. The calibrator operator should always
wear the wrist strap when handling cards.
2.2.2.3 ON/OFF Switch
The calibrator ON/OFF switch is located on the lower right section of the
front panel. When activated, the calibrator does not require time to
stabilize. No cards should be installed or removed from the calibrator
unless the ON/OFF switch is in the OFF position.
2.2.2.4 Test Slots
There are nine test slots on the calibrator. Each test slot is formed by an
edge connector and two card guides projecting from the front panel.
Eight of the test slots are dedicated to a different card type. The
remaining test slot is shared by several card types. Each test slot is
labeled according to the cards it can hold for calibrating.
2.2.2.5 Operator Station Cable/Umbilical Cable Receptacles
There are six receptacles for cable connections. Four of the receptacles
are used by the umbilical cables. One of the receptacles is used for all
three operator station cables. The final receptacle, labeled DATA CONC,
permits connection of the calibrator to port eight of a data concentrator to
enable controller cards installed in the calibrator to be configured from a
console.
2.2.2.6 Operator Station Case
An operator station case is built into the calibrator. Operator stations,
indicator display stations, and service transfer display station can be
installed in the operator station case when their respective cards are
being tested. Operator stations are not required to calibrate the
corresponding cards. A service transfer display station is required if the
service transfer unit is to be functionally tested.
