C3
1 RU HIGH 3 UNIT CARD CAGE WITH POWER SUPPLY
The C3 is a 1 RU (1.75”) high 19-inch rack-mountable card cage unit capable of
mounting up to three ComNet ComFit 1.0-inch wide modules.
The C3 is provided with one external 120-240 VAC power supply with a 12VDC at
2A output, and includes reverse polarity protection. Two separate isolated DC inputs
are provided for mission critical/high reliability applications where power supply
redundancy is required. ComNet ComFit PoE (Power over Ethernet) modules may
also be used, by replacing the power supply with a +48VDC unit, and connecting
the supply output to the DC power input of each PoE module. See Page 3 for wiring
instructions.
Any module may be hot-swapped without any impact to the operation of the other
modules within the card cage.
Ideally suited to those applications where rack space may be limited, the C3 may
be used in desk-top installations by the addition of user-installed rubber feet on the
bottom of the cage. It may also be installed as a rack by use of the two included rackmount adapter brackets. See Page 4 for installation instructions.
