5.4.2 24GE-24-Port 1000BASE-RJ45 L2/L3 Ethernet Interface Card
The 24GE is the 24-port 1000M Ethernet electrical interface card (RJ45). It implements the 24-
channel Ethernet Layer 2 and Layer 3 switching functions.
Functions and Applications
Functions
The 24GE provides 24 GE electrical interfaces to implement data access and line-speed
switching.
l When category 5 twisted pairs (straight-through cables or crossover cables) are used, the
maximum transmission distance is 100 meters.
l When category 5 twisted pairs (straight-through cables or crossover cables) are used, 1000
Mbit/s line-speed forwarding is supported between the 24 GE interfaces.
l These interfaces work in 10/100/1000 Mbit/s auto-sensing mode.
l These interfaces support the half duplex mode and full duplex mode. The full duplex mode
is most commonly used.
Applications
The 24GE can be installed into the XSIC slot on the AR2220, AR2240 and AR3260. On the
AR2220, two WSIC slots are combined into one XSIC slot.
