Compaq StorageWorks UltraSCSI RAID Enclosure (DS-BA370 Series) User's Guide (EK-BA370-UG. C02, September 1998)

Power Distribution

6–4 UltraSCSI RAID Enclosure

AC Input Box

The ac power distribution is provided through the ac input box (see

Figure 6–2) to the shelf power supplies. The ac power switch on each

ac input box controls the

ac distribution

to the associated power bus

(A or B). These ac input boxes are completely interchangeable and

have no physical or electrical differences between them. AC input

boxes do not have error indicators on them, nor do they generate any

error signals. Without an optional second ac input box, an ac input

box failure disables the enclosure.

Caution

The only compatible ac input box is the model

DS–BA35X–HE; model BA35X–HE cannot be used in an

UltraSCSI RAID enclosure.
