Figure 42 shows the G20X module.
The G20X module has 20 unpopulated mini-GBIC-based Gigabit Ethernet fiber ports. If you have one
MSM installed, all ports on the G20X module are switched through that MSM. If you have two MSMs
installed, the top 10 ports on the G20X module are switched through the MSM in slot A, and the bottom
10 ports are switched through the MSM in slot B during normal operation.
Using the G20X module allows you to fulfill line rate traffic.
All Gigabit Ethernet ports on these modules use SPF mini-GBIC connectors, either fiber or copper. The
module supports SFP fiber mini-GBICs 1000BASE-SX, 1000BASE-LX, 1000BASE-LX70, and 1000BASE-
ZX connectors. If you use SFP copper mini-GBICs, you must use the 1 Gigabit mini-GBIC; the G20X
module does not support copper 10/100/1000 SFP copper mini-GBICs.
The default configuration of the G20X module is as follows. All ports:
Are added to the default VLAN as untagged
Inherit the properties of the default VLAN (for example, protocol type and VLANid)
The G20X module supports any of the following mini-GBICs:
1 Gigabit copper mini-GBIC
SX mini-GBIC, which conforms to the 1000BASE-SX standard
LX mini-GBIC, which conforms to the 1000BASE-LX standard
ZX mini-GBIC, which conforms to the IEEE 802.3z standard
Table 15 describes the media types and the associated maximum distances for the G20X module.
