Installing the utility cards

Installing utility cards

Utility cards have onboard DIP switches and a faceplate

switch that you must set. To inspect and install the cards,

follow these steps.

CAUTION

Risk of equipment damage

Do not use a pencil to change switch

settings on the PCPs. The graphite dust

may damage and short the switches. Use

an appropriate nonconducting tool.

Step Action

1 Check each Utility card to make sure there are no

loose or bent parts.

2 Check that the switch settings on each Utility card

are correct:

a. Set all eight positions of the onboard switch to ON.

The ON position is up (toward the top of the board)

for each DIP switch position. If you have

Hospitality Voice Services (HVS), this allows

software control of the connection between

Meridian Mail and HVS while the faceplate switch

on the utility card is on. If you do not have HVS,

the onboard switch positions have no effect.

b. Set the faceplate switch on the utility card to

Normal (up). When this switch is in the Bypass

(down) position, it is used to loop back the last two

utility card RS-232 ports.

3 Install the Utility cards in the slots indicated in

“Installing cards in a one- or two-node EC 11” on

page 7-4.
