F-MB6X-RAC and F-MB6X-DC Chassis Power Components
The F-MB6X-RAC and F-MB6X-DC chassis have removable power supplies (PSUs) and power distribution unit
(PDU) (as shown in the figures below).The F-MB6X-RAC and F-MB6X-DC chassis are fully redundant and can run
using one or both PSUs. If using both, they share the load 50-50. One PSU can power all six cards in the chassis.
Replacement parts are available for the power supply units (#P-MB6X-AC-PSU and #P-MB6X-DC-PSU) and the
power distribution units (#P-MB6X-AC-PDU and #P-MB6X-DC-PDU).
IMPORTANT
The F-MB6X-MED power supply cannot be replaced without opening the chassis, which
would void the warranty. To replace the F-MB6X-MED power supply, you must return the unit to
Haivision. If field-serviceability is a requirement, we recommend that you keep a second F-MB6X-MED
chassis available on the premises.

Replacing the F-MB6X-RAC and F-MB6X-DC Chassis Power Supply
The PSU Power LED will show red to indicate an issue with the PSU. When this occurs, you should replace the
power supply. The PSUs are hot-swappable, which means that you do not need to power the chassis off to remove
a power supply. However, to keep the chassis running, only change one PSU at a time.
To replace the F-MB6X-RAC or F-MB6X-DC PSU:
CAUTION
Refer to
5 to prevent ESD damage to the equipment.
1.
Using a Phillips #2 head screwdriver, remove the two PSU retaining screws (one on the left side of the PSU
and the other beside the injector/ejector handle).
2.
Press the release button on the injector/ejector handle and pull the handle to release the PSU module.
