INSTALLATION

Two fans are located on the left-hand front side of each cabinet. The

cabinet’s power supply is located behind the fans; to the right of the power

supply are up to 12 CPs in individual slots.

Each CP is identified by a label

on the front. See Figure 2-10.

Remove the front cover of each cabinet.

2. Note any obviously bent or otherwise damaged circuit packs.

3. Check the CPs against the customer order. In case of irregularities

or damage, follow established notification procedures.

Danger: The System 25 cabinet contents are not user

serviceable. Some voltages inside the cabinets

are hazardous.

This equipment is to be

serviced only by qualified technicians.

The CPU/Memory (ZTN129 or ZTN130 [R3]) circuit pack has two shorting

plugs that are used for factory tests (see Figure 2-1 1). They should have

been removed at the factory.

If these shorting plugs have been accidentally

left in by the factory, the system may cold start when it should warm start.

Check the CPU/Memory CP; if the plugs are present, remove them. The

shorting plugs are located on the component side of the circuit pack.
