1. Interface

7200-24G2XG comes with two 10G XFP ports, 12 gigabit SFP ports and 12 gigabit

optical-electrical multiplex ports, and offers gigabit-level line rate of Layer 2/3 switching. With

auto-negotiation enabled, the gigabit electrical port supports automatic MDI/MDI-X

identification. The gigabit SFP optical module of short wave (850nm, multi mode), long wave

(1310nm, single mode) and long distance (1550nm) is supported on the SFP port. The SFP

copper port is also supported to offer flexible configuration. The SFP module is hot

swappable on the SFP port.

Note

7200-24G2XG offers 12 multiplex ports whose 10/100/1000BASE-T port is

SFP optical port. O nly o ne por t is a vailable at a t ime. The aut omatic

MDI/MDI-X function of the 10/100/1000M electrical port takes effect only

after auto negotiation is enabled.

2. LEDs

7200-24G2XG comes w ith various L ED i ndicators. The f ollowing t able describes t hese
