Using the Centillion EtherSpeedII Switch Modules
2-2 207344-B
To connect the ports on the patch panel to another Ethernet switch or an Ethernet
hub, follow these guidelines:
• Personal computers (PCs) and servers typically have network interface cards
(NICs) that are configured as MDI connections. To connect these devices, use
a straight-through cable.
• Hubs and other switches typically have connectors that are configured as
MDI-X. Some hubs and switches have ports that are set by a toggle switch for
either MDI or MDI-X operation.
— To connect a port set for MDI to the EtherSpeedII switch module port, use
a straight-through cable.
— To connect a port set for MDI-X to the EtherSpeedII switch module port,
use a crossover cable.
EtherSpeedII 100BASE-FX Switch Module
You connect the EtherSpeedII 100BASE-FX switch module ports to Ethernet
hubs and network devices using MT-RJ patch cables as appropriate for your
cabling environment.
Network Configuration Examples
The EtherSpeedII 10/100BASE-T switch module and the EtherSpeedII
100BASE-FX switch module are adaptable switches suitable for use in wiring
closets or network centers in conjunction with the Centillion 50/100 chassis.
Figure 2-1
shows an example of the EtherSpeedII switch modules in a sample
network configuration.
Note: For connector specifications for MDI and MDI-X ports, refer to
Appendix B, “Cables and Connectors
.”
Note: Because multimode fiber connections do not autonegotiate, the mode of
the devices at both ends of a link must be identical (HDX or FDX).
