PREFACE
SCOPE
This manual provides installation procedures for a standard VAX-11 /780 and its options, the BA I I-K
expander box and distribution panel, as well as the UNIBUS VAX-I 1/780 CU/CV. It also describes
the conversion of a UNIBUS VAX-11 /780 to a standard VAX- I I /780.
The manual is divided into four parts:
Part I - Standard VAX-11 /780
Part II - Options
Part III - UNIBUS VAX-11/780 CU/CV
Part IV - UNIBUS VAX-11/780 Conversion to Standard VAX-I I /780

1.1 UNPACKING AND INSPECTION
1. Check all boxes for external damage (dents, holes, smashed corners).
CHAPTER 1
INSTALLATION
2. Notify the customer of any damage and list it on the Labor Activity Reporting System
(LARS) report form (Figure 1-1 ). Include a note to clarify the extent of the damage.
3. Make sure all containers are sealed.
NOTE
Any opened packages or cabinets should be called to
the attention of the customer and documented on the
LARS report.
4. Remove the shipping/ accessory list in the "Open Me First" box and inventory the contents
of all boxes against the shipping list.
5. Notify the branch manager or branch supervisor of any missing or incorrect items. Advise
the customer to contact the carrier about any missing items.
6. Inform the branch service manager of the DIG IT AL Traffic and Shipping Department if the
carrier does not have the missing items.
7. Cut and remove strapping from the cabinet boxes.
8. Remove the cabinet boxes.
9. Install four leveling feet (Figure 1-2) on the cabinets using a 9/16-inch wrench. Use the hex
nuts and washers that were removed with the four red shipping brackets.
1.2 CABINET DISASSEMBLY PROCEDURES
The cabinets must be partially disassembled prior to being integrated into a system.
1.2.1 CPU Cabinet Partial Disassembly
1. Remove the two orange wheel lock assemblies from the CPU cabinet (Figure 1-3).
