It is recommended that suitable battery backup or
uninterruptible power supply (UPS) be installed so that
applications running on the Application Equipment
Module are not affected by commercial power outages.

the power supply, circuit cards, and the disk/tape unit as follows:
¥ the first card slot houses an MVME147 or MVME167 SBC card
¥ the second slot houses the MVME333-2 XCC card
¥ the third slot houses the MVME332XT or MVME332XTS card (for
CCR/Co-resident Module)
¥ the remaining slots are covered by blank faceplates to channel air flow
and thus maintain adequate cooling
!
CAUTION
Risk of hardware damage
Do not operate the Application Module if the blank
faceplates have been removed; overheating may cause
equipment damage.
