2-2 EMC Fibre Channel Disk-Array Processor Enclosure (DPE) Hardware Reference

Installing a Rackmount DPE

remaining supply and cord support the full load. You must use a

rackmount cabinet with ac power distribution, and have main branch

ac distribution that can handle these values for the number of DPEs

and DAEs that you will interconnect.

Cooling The ambient temperature specification is measured at the front door

inlet. The site must have air conditioning of the correct size and

placement to maintain the specified ambient temperature range. The

air conditioning must be able to handle the BTU requirements of the

DPEs and any connected DAEs.

Cabling

Requirements Use optical cables for connections to the external Fibre Channel

environment. Use a copper cable only (not an optical cable) to

connect a DPE to a DAE. The optical cables connect to the optical

GBIC on the SP.

DPE and DAE interconnections should maintain LCC consistency.

That is, one FC loop should connect the DPE’s SP A (which connects

internally to LCC A) and each DAE’s LCC A. The other FC loop

should connect the DPE’s SP B (which connects internally to LCC B)

and each DAE’s LCC B.

Do not leave an unused (that is, dangling) cable connected to any

Fibre Channel port because it may cause excess noise on the Fibre

Channel.

Addressing

Requirements The addressing requirements vary depending on the environment,

fibre port (fabric), or the fibre loop (FC-AL).

Fabric Envi ronments In a fabric environment, the DPE is addressed using the Source_ID

(SID) and the Enclosure Address (EA).

Source_ID

The Source_ID (SID) is a value that a switch in the external Fibre

Channel environment automatically assigns.

Enclosure Address (EA)

Each DPE and DAE on a back-end loop needs a unique enclosure

address (EA) that identifies the enclosure and determines disk

module addresses. The DPE has a fixed EA of 0 that you cannot

change. If you cable any DAEs to the DPE, you might want to set the

nearest DAE’s EA to 1, the next to 2, and so on. The enclosure address

is displayed in lights visible behind the front door.
