OPT-N2CD
The OPT-N2CD module provides two Gigabit Ethernet combo ports (RJ-45, SFP). The SFP type
of the Gigabit Ethernet ports supports both 100M and 1000M speed.
The feature of the OPT-N2CD is as follows:
Gigabit Ethernet Combo Port (A, B)
The Gigabit Ethernet combo ports are used for connecting R1-SW24L2B to the core network.
The OPT-N2CD module has two kinds of Gigabit Ethernet ports as follows:
y 10/100/1000Base-T Port (RJ-45 Connector)
y 100/1000Base-LX/SX SFP Port (LC Connector)
Both the RJ-45 connector and the LC connector (SFP module) cannot be used as Gigabit Ethernet
port at the same time.
For example, if a RJ-45 connector of 10/100/1000Base-T port is connected
to a Gigabit Ethernet device, a LC connector of SFP port is automatically disabled.
The following table lists the specifications of the Gigabit Ethernet port on the OPT-N2CD
module:
