Dual-Line Shelf
Limitations
These limitations apply when the HDM 2182 is used in a Dual-line
shelf. They must be observed to prevent intermittant data loss.
•
Because of heat build-up, only one HDM 2182 may be used in a
Dual-Line shelf.
•
Since the HDM 2182 draws more current than other AS2000
modules, two external power supplies must be used whenever
an HDM 2182 is placed in a Dual-line shelf. The power supplies
will not be fully redundant.
•
Whenever an HDM 2182 is used in a Dual-line shelf with an
NCM 2000 controller module, the HDM 2182 must be in the
first (left hand) slot and the NCM 2000 must be in the right
hand slot.
