10/100 Ethernet Switches & Routers

•10/100 Mbps Ethernet interface switches and routers that are directly connected to the data path are required to be configured for full duplex and 100Mbps. Auto Negotiation is not supported on these switches or routers.

NOTE: Cisco routers must always be set manually for 100Mbps, Full Duplex.

Gigabit Ethernet Switches & Routers

•It is preferred that Gigabit Ethernet interface switches and routers that are directly connected to the data path be configured for Auto Negotiate. Auto Negotiate is the default setting in UltraNet ConfigManager. Configuring the UltraNet Edge 3000 to Full Duplex in UltraNet ConfigManager is only allowed for devices directly connected that do not support Auto Negotiate.

NOTE: The UltraNet Edge 3000 Gigabit Ethernet interface must remain at the default setting of Auto Negotiate when connected to a Cisco router.

Ethernet Hubs

•Ethernet Hubs are not supported in the data path.

Fibre Channel Switches

NOTE: The UltraNet Edge 3000 contains an internal Fibre Channel switch application (FCSW) and when configured for F_port, an external Fibre Channel switch is not necessary unless more than two Fibre Channel ports are needed.

•McDATA supports F_port using the McDATA internal Fibre Channel Switch (FCSW) application over an Ethernet or ATM WAN interface.

•McDATA supports E_port extension and Device Extension (FC/SCSI Tape Pipelining) using Brocade and McData Fibre Channel switches over an Ethernet or ATM WAN interface.

•The FCSW application allows remotely connected N_ports to login and see other N_ports via this application using the standards compliant services.
