24GE (24-Port 1000M-RJ45-L2 Ethernet Electrical Interface Card)
Card Overview
24GE provides 24 GE electrical interfaces, which extend Ethernet forwarding and Layer 2 switching capabilities. The 24GE often applies to the enterprise headquarters and can connect to multiple devices by using the 24 GE interfaces.
A 24GE card can be installed in an XSIC slot of a router.
Figure 7-36 shows the appearance of a 24GE card.

24GE NOTE:
This card is supported in V200R001C00 and later versions. For AR2200 series, when this card is used on a router, the minimum bandwidth and maximum bandwidth supported by the card are both 1 Gbit/s, due to the backplane bandwidth restriction. For AR3200 series and AR3600 series, when this card is used on a router, the minimum bandwidth and maximum bandwidth supported by the card are 1 Gbit/s and 10 Gbit/s, respectively, due to the backplane bandwidth restriction. |
