block diagram
Figure 4-4 shows the block diagram of the Cisco Systems Intelligent Gigabit Ethernet Switch
Module.
The Cisco Systems IGESM has two ASICs for switching. It has 1 MB on chip cache for packet
buffers and supports 12 Gigabit Ethernet ports. The two ASICs are interconnected with 10
Gigabit link, which is shown as the 10 Gigabit Ethernet connection in Figure 4-4.
Each Switching ASIC has seven Gigabit Ethernet ports for blade servers and two ports for
external ports. It also has a port to the Management Module. The connection between the
ASIC and the Management Module links up at 100 Mbps.
