McDATA Sphereon 4400 Fabric Switch Installation and Service Manual
General Information
.
Figure 1-4 24-Port Ethernet Hub
Hubs can be daisy-chained to provide additional connections as more
switches (or other McDATA managed products) are installed on a
network. Multiple hubs are daisy-chained by attaching RJ-45
Ethernet patch cables and configuring each hub through a medium-
dependent interface (MDI) switch.
Error-Detection, Reporting, and Serviceability Features
The switch provides the following error detection, reporting, and
serviceability features:
• LEDs on switch FRUs and adjacent to Fibre Channel ports that
provide visual indicators of hardware status or malfunctions.
• Redundant FRUs (SFP transceivers and power supply
assemblies) that are removed or replaced without disrupting
switch or Fibre Channel link operation.
• A modular design that enables quick removal and replacement of
FRUs without the use of tools or equipment.
• System alerts and logs that display switch, Ethernet link, and
Fibre Channel link status at the EFCM Basic Edition interface,
client communicating with the management server, or customer-
supplied server (running a SAN management application).
• Diagnostic software that performs power-on self-tests (POSTs)
and port diagnostics (loopback tests).
