Troubleshooting and maintenance 5-3

Installation and Maintenance Standard 3.0 March 1994

Note: You need not, however, turn off the power to the Meridian 1 PBX.

You can safely handle Meridian Mail hardware while the switch is run-

ning, so long as the power to Meridian Mail is off.

Before touching any components, ensure that you are properly grounded by

putting on the wrist strap connected to the Meridian 1 cabinet. Static electric-

ity can irreparably damage sensitive electronic components.

Replacing components

Meridian Mail components are replaced in the opposite way to which they are

installed. (Refer to the appropriate sections in Chapter 1.) The only exception

to this is the removal of the Connector Board.

Removing the Connector Board

The connections between the Connector Board and the Meridian Mail cards

are too tight for you to remove the Connector Board in one step. It must, in-

stead, be removed one card at a time.

Courtesy down Meridian Mail and turn it off. (Refer to page 4-5.)

2 Grasping the top lock latches with one hand and the bottom latches with

the other, unlock all cards simultaneously and pull the assembly slightly

out of the cabinet.

3 Move all the lock latches so that they are at right angles to the cards.

DANGER

Shock hazard

Before removing or handling any Meridian Mail hard-

ware, ensure that the power switch on the 68k Card is

in the off (down) position.

CAUTION

Static electricity

The printed circuit boards are susceptible to static dam-

age. Before handling the PCBs take the appropriate

precautions.
