EMC Rails and Enclosures (CX4 Series Storage Systems) Field Installation Guide

Device placement requirements

Position in the cabinet

Devices with internal cooling fans or blowers that move air from

front to back (or vice versa) and not from beneath or above have no

special cooling requirements that direct placement in the cabinet. All

of the storage systems and enclosures mentioned in this document

have fans or blowers that move air from front to back.

In most cases, you should install devices starting at the bottom of the

cabinet. Installing bottom to top offers the advantages of stability and

convenient cable access from beneath.

We recommend that you arrange your enclosure as follows:

◆ Install the standby power supply (SPS) below any other

enclosures (at the bottom of an empty cabinet).

◆ Install the SPE (storage processor enclosure) directly above the

SPS.

◆ Install the specially marked disk-array enclosure (DAE)-OS

directly above the SPE.

◆ Install any additional disk enclosures above the DAE-OS.

Review your plan to make sure all devices will fit in the cabinet, and

review any requirements for filler panels. It is also important to verify

cabling lengths before installing any enclosure.
