14-4 Adding a node

Getting started

Standard 1.0 Modular Option EC Installation and Maintenance Guide November 1999

Note 3: Fill up the voice card slots: start from the left in a given

node, and begin with any VP8 cards designated for that node.

For example, a configuration of VP8, VP8, VP4, VP4 is

acceptable. A configuration of VP8, VP4, VP8 is not

recommended; it can lead to potential software configuration

problems if, in the future, you want to expand the number of

ports on the node. Also, you cannot skip a voice card slot. For

example, a configuration of VP8, blank, VP4 is not acceptable.

Powering up or down

The procedures in this chapter refer to powering a module on or

off.

If the system has more than one Meridian Mail module, power

on the modules in the following order:

1. module MM0

2. module MM1

3. module MM2

Power modules off in the opposite order. If the system has more

than one Meridian Mail module, power off the modules in

reverse order. That is, power off module MM2, followed by

module MM1, then module MM0.

To turn on an AC system, switch on the upper breaker in each

module before the lower breaker. To turn off an AC system,

switch breakers off in the opposite order.

To turn on a DC system, switch on the left DCEPS in each

module before the right one. To turn off a DC system, switch

DCEPS off in the opposite order.

CAUTION

Risk of equipment damage

You may blow the fuses on the Utility card

if you do not follow the sequence of steps

outlined in this manual to power up or

power down your Meridian Mail system.
