Selecting a Location

Select a location for your LanProbe where it will be the most useful. The LanProbe can only monitor traffic that is present on the LAN where it is attached. Because interconnect devices (bridges, for example) filter traffic, a LanProbe may need to be attached on each side of an interconnect device for complete collection of network statistics. In this respect, the placement of LanProbe affects the statistics collected.

Consider the following installation requirements when selecting a location for your probe:

The Fault and Activity LEDs on the front of LanProbe will light if any of the individual port LEDs on the rear panel light. To determine which port has activity or a fault, you are required to look at the port LEDs on the back panel. This should be zconsidered when selecting a location or LanProbe’s orientation in a rack.

A flat surface that is large enough to support the probe (requires clearance at rear and sides for cooling and rear panel access), adequate wall space, or space in a 19 inch rack or cabinet.

Agrounded power outlet (either 100-120/VAC or 220-240/VAC). Access to one or more Ethernet connection taps.

Access to an RS-232C connection (required only for Out-of-Band

zcommunication).

Access to a phone line and a modem within 50 feet (required only for Out- of-Band communication using a modem connection).

The MAC address for the probe can be found on the rear label. It is a good idea to make a note of this address prior to installing your LanProbe because some installation methods make it difficult to see the rear label without removing the probe.
