INSTALLATION

INSTALL SYSTEM CABINETS

Before beginning the cabinet installation, position the cabinet table within 2 feet of the ac power receptacle. Make sure that the cabinets are easily accessible from both the front and the back.

Position Cabinet(s)

Caution: A fully-equipped cabinet weighs 80 p o u n d s .

1.Unscrew and remove the upper rear panel of each cabinet. Do not unscrew the lower part with the 12 connectors.

2.Near the center of the backplane, note an address plug in one of the positions marked 1, 2, or 3 on the black address strip. (Position 4 is not used.) This indicates the cabinet number for software purposes. The position of the plug (1, 2, or 3) should agree with the position of the cabinet (Cabinet 1 on the bottom, etc.).

3.Use the CAB 1, CAB 2, and CAB 3 labels from the cable label sheets (Figure 2-7)to label each cabinet. Position the cabinet label in the box adjacent to connector 12 on the lower back panel. (The number may have already been stamped by the factory.)

4.Stack the cabinets on top of one another on the stand. If there is more than one cabinet, stack Cabinet 1 on the bottom arid Cabinet 3 on the top. Cabinet 1 contains the CPU/Memory (ZTN129 or ZTN130 [R3]), and Service (ZTN85 or ZTN131 [R3]) circuit packs (Figure 2-1 O). Do not replace the upper back panels yet.

Check Cabinet Contents

Check to make sure that the cabinets have been delivered with the correct circuit packs (CPs). Table 2-Blists available CPs, their functions, and their protectors. If the system has TN760B Tie Trunk CPs, you may also have to set the option switches on the CPs. See “Set TN760B Option Switches” in Appendix C for details.
