Cabletron Systems SmartSwitch 2200 Instruction Sheet
SmartSwitch 2200 DC POWER SUPPLY INSTRUCTION SHEET
This document provides additional information to the SmartSwitch 2200 user’s guide shipped with your device. This
document describes how to connect the dc version of a SmartSwitch 2200 device to 48 or 60 Vdc (48/60 Vdc) power
sources. Except for special grounding considerations for a particular type of rack installation and the two dc power
supplies, the device is installed and functions the same as the ac version. The two dc power supplies in the device have
their own on/off switch and input power strip, and are each rated at 125 watts. The on/off power switches and input
power strips are similar to the ones shown in Figure 1.

ONLY QUALIFIED PERSONNEL SHOULD PERFORM THESE INSTALLATION PROCEDURES.
TO REDUCE THE RISK OF ELECTRIC SHOCK OR ENERGY HAZARDS:
• CONNECT TO A RELIABLY GROUNDED 48/60 VDC SELV SOURCE.
• ENSURE THE BRANCH CIRCUIT OVERCURRENT PROTECTION IS RATED AT A MINIMUM
OF 15 A.
• USE 12 or 14 AWG SOLID COPPER CONDUCTORS ONLY.
• ENSURE THAT A READIL Y A CCESSIBLE DISCONNECT DEVICE THA T IS SUITABL Y APPR OVED
AND RATED, IS INCORPORATED IN THE FIELD WIRING.
TO BE INSTALLED IN A RESTRICTED ACCESS AREA IN ACCORDANCE WITH THE NEC OR THE
AUTHORITY HAVING JURISDICTION.

DC POWER SUPPLY REQUIREMENT
Input power can be 48 or 60 Vdc with a maximum current drain of 4.9 A for each power supply.
INSTALLATION REQUIREMENT
Each dc power supply input requires either a 48 Vdc or 60 Vdc power source supplied by three 18 AWG (American
Wire Gauge) copper wires. These wires must be terminated with either ring or spade terminals that accept a #6 screw.

BONDING THE DC DEVICE
If the device is going to be mounted in a rack and needs to meet the GR-1089-CORE Section 9 bonding requirements,
use the following instructions to install the device into a 19-inch rack.
1. Attach the strain-relief bracket as described in the user’s guide.
2. If the SmartSwitch 2200 device uses the side mounting brackets, proceed to step 3. If the device uses the bottom
mounting brackets, proceed to step 4.
3. To install a device with side mounting brackets, proceed as follows:
a. Remove and discard the four cover screws (two from each side) located along the front edges of each side of the
device.
b. Remove the paint from around the area near the mounting holes on the left and right side of the cover of the
device. See Figure 2.
c. Apply a thin layer of anti-oxidant to the surface where the paint was removed.

d. Locate the four 6-32 x 3/8-inch flathead screws in the rackmount kit. Use these screws to attach the rackmount
brackets to the sides of the device as shown in Figure 2.
e. With the mounting brackets installed, position the device between the vertical frame members of the 19-inch
rack and fasten it securely with thread-forming mounting screws (user supplied) as shown in Figure 3.
