XGM3S-2xf Option Card
The XGM3S-2xf option card (Figure 9) allows you to add one or two 10-Gigabit XFP optical ports to
Slot A on the rear panel of the E4G-400 router. These ports support synchronous Ethernet and can be
used for stacking connections or data links.

XGM3SB-4sf Option Card
The XGM3SB-4sf option card (Figure 10) allows you to add up to four 10-Gigabit SFP+ optical ports to
Slot B on the rear panel of the E4G-400 router. These ports support synchronous Ethernet and can be
used for data links. The XGM3SB-4sf option card supports either SFP+ optical modules or the SFP+
direct-attach passive copper cable.

E4G-B16T1E1 Option Card
The E4G-B16T1E1 option card (Figure 11) allows you to add 16 T1/E1 ports with pseudowire emulation
to slot B on the rear panel of the E4G-400 router. This option card has two MRJ21 connectors, each one
providing eight ports. Connections to these connectors are made in either of the following ways:
● A special fan-out cable that connects to the module and provides eight separate RJ-45 connectors at
the other end. (See Appendix B for more information about this cable.)
● A straight MRJ21-to-MRJ21 cable that connects to a breakout panel
