1.6.3 7200-24 Module
Figure 1-10 shows the basic appearance of the 7200-24, which is the line card module of the
DES-7210/7206. The 7200-24 provides twelve 10/100/1000BASE-T electrical interfaces and
twelve optical/electrical combo 1000M interfaces, which deliver L2/L3 wire-speed switching.
It is hot swappable while supporting the hot swappability of the SFP port.
