Accessing the switch for the first time
Connecting the switch to a configuration terminal
The S5170-EI series and S5570S-EI series switches each provide a serial console for connecting to
a configuration terminal.
In Figure 31, the switch is connected to a configuration terminal (PC as an example) from the serial
console port.

As shown in Table 12, two types of console cables can be used for connecting the switch to a
configuration terminal.

The signal pinout for a DB9-to-RJ45 console cable depends on the vendor of the cable. To avoid
abnormal configuration terminal display, use a serial console cable provided by H3C. For more
information, see Table 8. To prepare a serial console cable yourself, make sure the signal pinout for
the RJ-45 connector is the same as that shown in Table 13.
Connecting a DB9-to-RJ45 console cable
CAUTION:
Follow these
guidelines when you connect a DB9-to-RJ45 console cable:
•
Identify the mark on the serial console port and make sure you are connecting to the correct port.
•
The serial ports on PCs do not support hot swapping. To connect a PC to an operating switch,
first connect the PC end. To disconnect a PC from an operating switch, first disconnect the switch
end.
