ETH Management Port (Combo)
The ETH management port (combo) consists of an electrical port and an optical port. You can
connect the electrical or optical port to a configuration terminal or network management
workstation to set up the onsite or remote configuration environment. The electrical and optical
ports are multiplexed, and only one of them can work at a time.
The combo electrical port uses a Category 5 or higher category network cable.

IEEE802.3ab
Supported rate: 10/100/1000 Mbit/s auto-sensing
Full-duplex
100 m
NOTE
The combo port automatically selects the working mode 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 has an optical module installed and is in Up state, 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 and fiber installed and the electrical port has a network cable
connected, the optical port is used for data switching after the switch restarts.
