1. Interface

7200-24: It provides twelve 10/100/1000BASE-T electrical ports and twelve optical/electrical

combo 1000M interfaces, and supports up to twenty-four 1000BASE-T interfaces or 12+M

1000BASE-T interfaces and N 1000BASE-X interfaces, where M plus N equals 12. When

the f unction of aut omatic nego tiation is en abled, t he 100 0M el ectrical i nterface s upports

automatic MDI/MDI-X identification. The SFP ports support short-wave (850nm, multi-mode)

and long-wave (1310nm, single-mode) 1000M SFP optical modules and long-wave (1550nm)

1000M SFP optical modules and SFP copper ports, thus facilitating configuration for users.

Note

The 7200-24 provides twelve SFP optical ports and 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 7200-24 provides various system LEDs, as described in the following table:
