F-Mb21B-R - Haivision MB6 Installation Manual

The F-MB21X-R has two PSUs (Power Supply Units) 600W each, with a fully redundant power supply with hot-
swap and hot-plug ability. Each PSU module can support the maximum load. If both PSU modules are present, they
share the load (default configuration).
The F-MB21X-R chassis is designed to tolerate the loss of one AC supply (120/240V) source without loss of installed
card functionality. Since there are two power inlets on the F-MB21X-R chassis, the cards in the chassis can operate
with only one powered.

F-MB21B-R

The 7-inch rack unit (4 RU) F-MB21B-R chassis holds any combination of up to 21 Makito X, classic Makito, Barra-
cuda, and Torpedo mini-blades.
Each socket on the PDU (Power Distribution Unit) powers a pair of PSUs (Power Supply Units). Two PSUs are suffi-
cient to power a fully loaded chassis.
The F-MB21B-R chassis is designed to tolerate the following without loss of installed card functionality:
• The loss of one AC supply (120/240V) source.
Since there are two power inlets on the F-MB21B-R chassis, the cards in the chassis can operate with only one
powered; however, the chassis would not be fully redundant.
• The loss of one or two PSUs of the four PSUs in the F-MB21B-R chassis in any combination.
The following replacement part is available for the power supply (#P-MB21B-PS).
