Meridian 1 option 51 upgrades 9-57

Upgrade preparation

Some preparation is required before the conversion of the option 51 hardware
and software begins. You must first do the following:
— Inventory all equipment required for the upgrade.
— Provide appropriate power and ground for the increased electrical load of
the option 61C.
— Install the option 61C hardware.
— Back up the customer database to disk by doing a data dump.
Power and ground
Clean power and a good ground are prerequisites to any switch upgrade.
Refer to Upgrade engineering (553-3001-150) to verify that sufficient power
is available for the new equipment. Follow the procedures outlined in
Meridian 1 system installation procedures (553-3001-210) when installing
new power equipment and to provide a good ground for the equipment.
Installing option 61C hardware
The option 61C equipment is preconfigured at the factory according to your
requirements. The equipment includes the pedestal, Core/Network modules,
IPE module, cards, and top cap. Cards such as IOP/CMDUs and power
supplies are shipped in separate packages to prevent damage to the cards.
Figure 9-9 shows the option 61C common equipment and intelligent
peripheral equipment modules and cards installed in their typical card slots.
To install the option 61C at your site, first follow the procedures in
Meridian 1 system installation procedures (553-3001-210) and then continue
with the procedures in this chapter.
Also install any external cables that can be installed at this time without
interrupting service (see "Installing external cables" on page 9-66).
