INSTALLATION AND OPERATION MANUAL
CNMC[2]SFP[POE][/M] Series
10/100/1000MBPS ETHERNET MEDIA CONVERTERS
WITH 100FX AND 1000FX SUPPORT
The ComNet
™
CNMC[2]SFP[POE][/M] Series products convert one or two Ethernet
signals from electrical to optical and optical to electrical. The devices accept a 10/100
or 1000Mbps electrical input and convert this to a 100/1000Mbps optical output
and the 100/1000Mbps optical input back to the 10/100/1000Mbps electrical
output. The products in this series use either one or two optical fibers, depending
upon the selection of sold-separately SFP optical module. The CNMCSFPPOE/M
additionally supplies IEEE802.3at (30W) compliant Power over Ethernet (PoE) to the
remote end.
The CNMC[2]SFP[POE][/M] Series is designed to operate in harsh industrial
environments with no electrical or optical adjustments required (Plug and Play).
The optical data rate of 100FX or 1000FX is selected by a dip switch. See Figure 9
on Page 6 for dip switch settings. “Auto-Negotiating” is supported on the copper
interface side.
LED indicators are provided for confirming equipment operating status. See Figure
10 on Page 6 for LED indicator descriptions.
See Figures 1 – 11 for complete installation details.
The CNMCSFP/M and CNMCSFPPOE/M are supplied in a surface mount “Mini”
package. The ComFit units in this series can be surface mounted or installed in the
ComNet card cages. See Figures A and B on Page 7 for mounting instructions.
