DMS 1600, DMS 2000, DMS 3200, and DMS 3600 • Maintenance and Modifications 100
Maintenance and
Modifications
This section covers maintaining and modifying the DMS matrix switchers, including:
• Mounting the Switcher
• Removing and Installing the I/O Board or Blank Panel
• Removing and Installing the Power Supply Module (DMS 1600 and DMS 3600)
• Removing and Installing a Fan Module (DMS 1600 and DMS 3600)
• Removing and Installing Button Labels
Mounting the Switcher
The DMS 1600 is housed in a rack-mountable, 4U high metal enclosure with mounting
flanges for standard 19-inch racks. The DMS 2000 is in a 3U high enclosure. The
DMS 3200 is in a 5U high enclosure. The DMS 3600 is in an 8U high enclosure.
UL Guidelines
The following Underwriters Laboratories (UL) guidelines pertain to the installation of the
matrix switcher into a rack.
• Elevated operating ambient — If installed in a closed or multi-unit rack assembly,
the operating ambient temperature of the rack environment may be greater than room
ambient. Therefore, consider installing the equipment in an environment compatible
with the maximum ambient temperature specified by the manufacturer [Tma = +32 to
+122 °F (0 to +50 °C)].
• Reduced air flow — Installation of the equipment in a rack should be such that the
amount of air flow required for safe operation of the equipment is not compromised.
• Mechanical loading — Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
• Circuit overloading — Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of the circuits might have
on overcurrent protection and supply wiring. Appropriate consideration of equipment
nameplate ratings should be used when addressing this concern.
• Reliable earthing (grounding) — Reliable earthing of rack-mounted equipment
should be maintained. Particular attention should be given to supply connections other
than direct connections to the branch circuit (such as the use of power strips).
Mounting Instructions
If desired, rack mount the switcher as follows:
1. Insert the switcher into the rack, aligning the holes in the mounting bracket with those in
the rack.
2. Secure the switcher to the rack using the supplied bolts.
