XGM3SB-4sf Port Option Card
The XGM3SB-4sf option card (Figure 134) allows you to add up to four 10-Gigabit SFP+ optical ports to
Slot B on the rear panel of the Summit X460 series switch. These ports support synchronous Ethernet
(Sync-E). The XGM3SB-4sf option card supports either SFP+ optical modules or the SFP+ direct-attach
passive copper cable.

VIM4-40G4X Versatile Interface Module for the
Summit X670 Switch
The rear panel of the Summit X670 switch provides a slot for an optional VIM4-40G4X versatile
interface module. The VIM4-40G4X module (Figure 135) provides four unpopulated cages for QSFP+
optical modules or QSFP+ compatible active or passive cables.
Ports S3 and S4 can be enabled as native stacking ports for the Summit X670 switch. Each physical port
can be configured to operate as a single 40-Gbps port or as four 10-Gbps ports. When the port operates
in 40-Gbps mode, you can connect the port using either a QSFP+ direct-attach cable or an installed
QSFP+ module and compatible fiber optic cable. When the port is configured to operate in 10-Gbps
mode, you must connect it using a special 1-to-4 fan-out cable.
The VIM4-40G4X module requires ExtremeXOS 12.6.1 software (or later) installed on the Summit X670
switch.
