1.6.4 7200-48 Module

Figure 1 -11 shows t he ba sic app earance of t he 7200-48, t he l ine c ard m odule of t he

DES-7200 series. The 7200-48 provides 44 10/100/1000BASE-T electrical 1000M interfaces

and 4 optical/electrical combo 1000M interfaces, which deliver L2/L3 wire-speed switching.

The 7200-48 is hot swappable.

1. Interface

7200-48 provides 44 10/100/1000BASE-T el ectrical por ts and 4 optical/electrical c ombo

1000M i nterfaces, and s upports up t o 48 1000BASE-T i nterfaces or 44+M 1 000BASE-T

interfaces and N 1000BASE-X interfaces, where M plus N equals 4. When the function of

automatic neg otiation i s enabled, t he 1000M e lectrical 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.

Note

The 7200-48 provides four 10/100/1000BASE-T SFP optical ports that are

in the multiplexing form. In other words, each SFP port corresponds to one

10/100/1000BASE-T port, and only one 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 ef fect onl y when auto ne gotiation i s

enabled.
