v Fourteen internal ports, one connected to each of the processor blades.
v Two internal full-duplex 10/100 Mbps ports connected to the management
module.
v
Four external 1000BASE-T Ethernet ports for 10/100/1000 Mbps connections to
external Ethernet devices, such as backbones, end stations, and servers. These
ports are identified as Ext1, Ext2, Ext3, and Ext4 in the switch configuration
menus and are labeled 1 through 4 (from top to bottom) on the switch module,
as shown in the preceding illustration.
