Appendix C

Installing an Expander Cabinet

Expansion must be to the right of the system cabinet (as you view the

cabinet from the front). See Figure 1–4 which shows a system, expander,

disk, and tape cabinet conﬁguration. First unpack the expander cabinet.

Remove the system cabinet’s side panel and top cover. Then bolt the

expander and system cabinets together. Finally, install the DWMBB/A

module (if required) and connect the interface cables according to the

system conﬁguration. For more information on the expander cabinet,

see the VAXBI Expander Cabinet Installation Guide or the H9657–EU

Installation Guide.
