INSTALLATION
Figure 5. Console Port Connection
2.3.1 RJ-45 Pin Assignment
This RJ-45 connector provides an RS-232 DCE (data communication equipment) asynchronous serial connection
for local management.
2.3.2 Accessory Cable
This DB9F to RJ-45 cable provides a connection for the RS-232. This cable is used between the MSW-4424C(S) and
the serial port of terminal.
2.4 Electrical Installation
AC power module is supplied to the MSW-4424C through a standard IEC C14 3-prong receptacle, located on the
front of the module. Any national power cord with IEC C13 line plug may be used to connect AC power to the power
module.
Figure 6. IEC (AC) Power Connector Pin Assignment
MSW-4424C(S) switches also provide DC module for power connection. The user must connect the device only to
DC input source that has an input supply voltage from -36 to -60 VDC. If the power you use is not in this range, the
device might not operate properly and there is great possibility that the device might be damaged.
