II. Connection procedure
Follow these steps to connect the console cable to configure the switch through a
terminal.
1)
Connect the DB-9 female connector of the console cable to the serial port on the
PC or the configuration terminal.
2) Connect the RJ-45 connector of the console cable to the console port on the
switch.
Note:
The RS-232 serial port is not hot swappable. You are recommended to disconnect the
power supply to the PC or terminal before connecting the DB-9 connector. Or you can
first connect the DB-9 connector and then insert the RJ-45 connector of the console
cable into the console port.
4.7.2 Connecting the AUX Cable
The AUX cable is used for remote configuration of the S7500 series through Modem
dial-up connection.
I. Introduction
The AUX cable is an 8-core shielded cable. It has an RS-232 RJ-45 connector at one
end for the console port on the switch, and a DB-9 male connector at the other end for
a 9-pin serial port on the Modem. The AUX cable is the same as the console cable. For
details, see Figure 4-11 and Table 4-1.
