Attribute Description
Working mode Duplex Universal Asynchronous Receiver/Transmitter (UART)
Baud rate 9600 bit/s, 19200 bit/s, 38400 bit/s, 57600 bit/s, or 115200 bit/s
Default value: 9600 bit/s
Mini USB port
The mini USB port is connected to a console for on-site configuration. When both the Mini
USB and console port have a cable connected, only the Mini USB port works.
Indicator Description
The S5700-52X-PWR-LI-AC has the same types of indicators as the S5700-28X-PWR-LI-
AC. For details, see Indicator Description.
Power Supply Configuration
The S5700-52X-PWR-LI-AC has a built-in power module and does not support pluggable
power modules. It can provide PoE power supply and connect to an RPS1800 power supply
for power redundancy. Table 3-123 lists its power supply configurations.

Figure 3-46 shows the power supply mode of a built-in AC PoE power module (PWR). The
PWR module receives AC power from an external power source and provides two outputs: 12
V and -53 V. The 12 V output is provided for the chassis, and the -53 V output is provided for
PDs.
