NOTE
By default, a combo port works in auto mode, in which the port type is determined as follows:
l If the optical port has no optical module installed and the electrical port has no network cable
connected, the port type depends on which port is connected first. If the electrical port is connected
by a network cable first, the electrical port is used for data switching. If the optical port has an
optical module installed first, the optical port is used for data switching.
l If the electrical port has a network cable connected and is in Up state, the electrical port is still
used for data switching when the optical port has an optical module installed.
l If the optical port, no matter in Up or Down state, has an optical module installed, the optical port
is still used for data switching when the electrical port has a network cable connected.
l If the optical port has an optical module installed and the electrical port has a network cable
connected, the optical port is used for data switching after the switch restarts.
You can configure a combo port as an electrical or optical port using the combo-port command.
Console port
The console port is connected to a console for on-site configuration. The port must use a
console cable. The console port is used when a switch is powered on for the first time. For
details about the attributes of a console port, see Table 3-60.
Table 3-60 Attributes of a console port

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 S5701-28TP-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 S5701-28TP-PWR-LI-AC has a built-in power module and does not support pluggable
power modules. It can connect to an RPS1800 power supply for power redundancy. Table
3-61 lists its power supply configurations.
