5-4 Installing a column or module

Installing columns and modules

Standard 1.0 Modular Option EC Installation and Maintenance Guide November 1999

Note 1: References to Overlay 37 apply only to a Meridian Mail

module that is being added to an existing Meridian 1 column.

Enter Overlay 37 commands on the Meridian 1 console. Ignore

the references to Overlay 37 if you are not adding a module to

an existing Meridian 1 column.

Note 2: If you are installing a module in a DC system, you

cannot set power supply switches to on, as instructed at the end

of “Adding a Module to a Column,” because you have not yet

installed the power supply.

If you are installing a module in an AC system, leave the shelf

breakers off.

Module doors and I/O

cover

To install power supplies, disk drives, and tape drives, and to

check the printed circuit packs, you need to open the front door

of the module. To verify or change backplane switch settings,

and to verify, remove, or fit EVB terminators and address

jumper boards, you need to open the rear door of the module

and remove the

I/O cover. To install cables, you need to open

the rear door of the module and you may need to remove the I/O

cover.

For this reason, you should leave the module doors open after

you install the module.

Complete the installation of all modules of your Meridian Mail

system before you proceed to the next chapter.

Module identification

You can identify modules by a label at the right side of the front

of the case. Modules are numbered Module 0, 1, and 2. In this

manual, the modules are referred to as MM0, MM1, and MM2.

If you are expanding an existing system and are adding a new

module, the new module is shipped with a blank label.

Complete the label as follows:

• The module that contains Meridian Mail node 1 is module

MM0.

• The other module in any two-module system is module

MM1.
