Take the following steps to connect the console cable, when configuring the switch on the terminal. 

1)  Plug the DB-9 female plug of the console cable to the serial port of the PC or the terminal where the 

switch is to be configured. 

2)  Connect the RJ-45 connector of the console cable to the console port of the switch. 

The AUX cable is used for the remote Modem dial-up configuration for the S7900E series. 

The AUX cable is an 8-core shielded cable. One end is an RJ-45 RS-232 connector, which can be 

plugged into the console port. The other end is furnished with a DB-9 connector, which can be plugged 

into the DB-9 socket on the Modem. The AUX cable is the same as the console cable. For details, see 

 and 

. 

Follow these steps to connect the AUX cable: 

1)  Plug the RJ-45 connector of the AUX cable into the console port. 

2)  Plug the DB-9 connector of the AUX cable into the serial port of the analog Modem. 

When connected to an external PoE power supply, the S7900E series can monitor the running status of 

the external PoE power supply through the COM port. The COM ports (one RS-485 port and one 

RS-232 port) of the S7902E and the S7903E-S are located on the rear panel of the chassis.  

When the S7903E, S7906E, S7906E-V, or S7910E provides PoE supply through the PSR1400-D, they 

can monitor the running status of the PoE supply through the PoE monitoring port (one RS-485 port) on 

the PSR1400-D.
