The 7200-24P 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, and on ly on e port can 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.
7200-24P does not support the hot pull-out operation. You need to perform
the following operations to achieve it:
1. Disconnect all cables connected with cable card ports;
2. Hold the Mode button for over three seconds until all LEDs on the
cable card ports are off;
3. Configure the pull-out operation through software commands. (For
relevant software configuration commands, refer to the corresponding
software description.)
