Appearance Side and Service Side

All system enclosures have an appearance side and a service side:

•

The appearance side of an enclosure contains disk drives. System enclosures are

usually arranged so that the appearance side is the most visible side. The

appearance side is covered with a door, which must remain closed during normal

operation to ensure proper cooling.

•

The service side of an enclosure contains the PMF CRUs and IOMF CRUs and is

the connection point for all cables to and from the enclosure.

The service side can be equipped with an optional door, which covers cabling and

secures access to components.

Enclosure Arrangements

Enclosures are stackable. You can arrange your enclosures in any convenient way, as

long as you do not stack more than one system enclosure on top of another. This

illustration shows one double-high stack and two single-high enclosures.
