Dual-Line Shelf

Limitations

These limitations apply when the HDM 2180 is used in a Dual-line

shelf. They must be observed to prevent intermittant data loss.

•

Because of heat build-up, only one HDM 2180 may be used in a

Dual-Line shelf.

•

Since the HDM 2180 draws more current than other AS2000

modules, two external power supplies must be used whenever

an HDM 2180 is placed in a Dual-line shelf. The power supplies

will not be fully redundant.

•

Whenever an HDM 2180 is used in a Dual-line shelf with an

NCM 2000 controller module, the HDM 2180 must be in the

first (left hand) slot and the NCM 2000 must be in the right

hand slot.

•

When an HDM 2180 is used in a Dual-line shelf without an NCM

2000, the HDM 2180 must be mounted in the right hand slot

(slot 2).
