CAUTION

Risk of system interruption

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.

As shown in Figure 14, slots in the front of the Application Module house 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.
