1.6.2 7200-24G Module
Figure 1-9 shows the basic appearance of the 7200-24G, which is the line card module of
the DES-7210/7206. 7200-24G provides 1 2 10 00M SFP por ts an d 1 2 100 0M
optical-electrical multiplexing ports, and supports up to 24 1000BASE-X interfaces or 12+M
1000BASE-X i nterfaces and N 100 0BASE-T interfaces, where M plus N eq uals 12. It
features the function of layer-2/3 wire speed switching. The 7200-24G module supports the
hot swap function and also supports hot swapping of SFP ports.

1. Interface
7200-24G provides 12 1000M SFP ports and 12 1000M optical-electrical multiplexing ports.
It features the function of layer-2/3 switching with the 1000M wire speed. When the function
of aut omatic negot iation is enabl ed, t he 1 000M el ectrical i nterface s upports aut omatic
MDI/MDI-X identification. The SFP ports support short-wave (850nm, m ulti-mode) and
long-wave ( 1310nm, s ingle-mode) 100 0M SFP o ptical m odules a nd long-wave (1550nm)
1000M SFP optical modules and SFP copper ports, thus facilitating configuration for users.
In addition, the SFP port supports hot swappability of the SFP module.
Note
The 7200-24G provides twelve SFP optical ports of 10/100/1000BASE-T
ports t hat ar e i n t he c ombo f orm. I n ot her words, eac h SFP por t
corresponds t o on e 1 0/100/1000BASE-T por t, a nd only one por t c an be
used at a time, with the other being unavailable. The MDI/MDI-X automatic
identification of the 10/100/1000M electrical ports takes effect only when
auto negotiation is enabled.
2. LEDs
The 7200-24G provides various system LEDs, as described in the following table:
