As part of this SuperStack II system, the Switch 1100 meets the challenge of modern LANs and allows you to add features and capacity as your network expands. -
Page 13: Switch 1100 - Front View Detail
Figure 1 Switch 1100 — Front view Port Connections 10BASE-T Ports The Switch has 12 or 24 10BASE-T ports configured as MDIX (cross-over). The maximum segment length is 100m (328ft) over Category 3, 4, or 5 twisted pair cable. As these ports are configured as MDIX (cross-over), you need to use a cross-over cable to connect to devices whose ports are MDIX-only. -
