The 4-Port Gigabit Ethernet ISE line card ships with 256 MB of route memory and 512 MB of packet 
memory. Route memory is field serviceable. For more information on memory, see the 

The 10-Port 1-Gigabit Ethernet line card, which is designed for high-density and server-aggregation 
applications, provides the Cisco 12400 and 12800 Routers with 10 optical 802.3 Gigabit Ethernet 
interfaces on a single line card. These interfaces provide high-speed connections to other network 
devices, such as another Cisco 12000 Series Router, other routers, or layer-2 or layer-3 switches that 
support Gigabit Ethernet interfaces. 

 shows a front view of the line card.

The 10 ports on the front panel of the line card are numbered 0 through 9, from the top of the card to the 
bottom. Each port consists of a receptacle for a field-replaceable SFP laser optical transceiver module, 
which is inserted into the receptacle to provide the Gigabit Ethernet optical interface.

Next to each port on the line card are three green LEDs, aligned vertically and labeled from top to bottom 
as follows: LINK, ACTIVE, and RX FRAME. 

The 10X1GE-SFP-LC-B version of this card is not shown. The 10X1GE-SFP-LC-B model 
of the 10-Port 1-Gigabit Ethernet line card is enhanced with minor hardware features that 
are not available with the original design.
