Removing and Installing the Power Supply Module
(DMS 1600 and DMS 3600)
NOTES:
• The redundant power supply is an optional accessory for the DMS 1600.
The redundant power supply is standard for the DMS 3600.
• The power supply modules are hot-swappable. Either power supply can be
removed or installed without powering down the switcher.
The primary and redundant power supply modules are identical and hot-swappable. Each
power supply module has a 2-color LED, visible on the rear panel, that indicates the status
of the power supply outputs. If the LED is lit green, the power supply is operating normally. If
the LED is lit red, the supply has failed and should be replaced at the earliest opportunity.
ATTENTION: The DMS matrix switchers use double pole/neutral fusing. Power must
be disconnected before servicing internal components.
Removing the Power Supply Module
Remove a power supply module as follows:
1. Rotate the left and right knurled knobs to completely loosen the screws.
2. Gently pull on the handle to loosen the power supply from the backplane (see figure 69).
3. Slide the power supply out of the chassis.
