Upgrade preparation

553-3001-250 Standard 14.00 August 1996
Some preparation is required before the conversion of the ST or STE
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 tape or disk by doing a data dump.
Note: Obtain extra-high-density floppy disks containing system
software from your Northern Telecom representative.
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
Option 61C equipment is configured at the factory according to customer
requirements. This equipment includes the pedestal, Core/Network module,
IPE module, cards, and top cap. Some cards, such as the MDUs and power
supplies, are shipped in separate packages to prevent damage to the cards.
Figure 4-7 shows 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 on the following pages of this chapter.
Also install any external cables that can be installed at this time without
interrupting service (see "Installing external cables" on page 4-96).
