Connecting a Device to the Piranha Switch
The Piranha Switch is a "plug-and-play" switch that can automatically learn MAC
addresses and direct network traffic accordingly. The Piranha Switch supports up
to 8192 MAC addresses.
Supported Media
You can connect a device to a port of the Piranha Switch using Category 3 or
Category 5 Unshielded Twisted-Pair (UTP) wiring. The wire must have an RJ-45
Ethernet plug in order to connect to a port of the Piranha Switch.
Determining Whether to Use a Cross-over or Straight-
through Wire
Like the out-ports of a repeater hub, the ports of the Piranha Switch are MDI-X
(cross over) RJ-45 jacks. Depending on which kind of device you are connecting
to the Piranha Switch, you will need to use either a "straight-through" or "cross-
over" wire.
Refer to the following table to determine which wiring to use to connect various
devices to the Piranha Switch:
See diagram for sample topologies.
Understanding the Status Lights
The status of each port on the Piranha Switch is indicated by a light:
Device Type Wire To Use
Server (NIC or Matrox Shark 100
Multiport NIC)
straight-through
Server (Piranha SwitchNIC) cross-over
Workstation (Network Interface Card) straight-through
Repeater Hub (MDI Uplink Port) straight-through
Repeater Hub (MDI-X) cross-over
Switch (another Piranha Switch, or any
other Ethernet switch with MDI-X jacks)
cross-over
