7. For an I/O board, align the board with the left and right chassis
guides (above).
8. Gently slide the board or blank panel into the enclosure. For an I/O
board, slide the board toward the front panel until it meets resistance.
9. Gently seat the board or panel in the backplane.
10. Use a screwdriver to tighten the left and right knurled knobs to lock
the board or panel in place.
Removing and Installing a Power Supply Module
(DMS 1600 and DMS 3600)
Each power supply module has a two-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.
LEDs with identical meanings are also on the front panel.
The two power supply modules (primary power supply and redundant
power supply) are identical and hot-swappable; you do not need to
power down the switcher to install or remove either power supply
module.
ATTENTION: The DMS matrix switchers use double pole/
neutral fusing. Power must be disconnected before servicing
internal components.
NOTE: DMS 2000 and DMS 3200 — The power supplies are xed
in place and are not eld replaceable.
1. Rotate the left and right knurled knobs to completely loosen the
captive screws (see gure 15).
Align the power
supply edges with
the plastic guides.
