Connecting the Probe

LanProbe communicates with Agilent NetMetrix either through the In-Band network connection or by using an Out-of-Band serial connection. You can establish both In-Band and Out-of-Band connections to give you the option of communicating with the probe either over the network or over the serial link, respectively.

The In-Band connection adds a slight amount of traffic to the network, but is faster than the Out-of-Band connection. The disadvantage of using only the In-Band connection is that certain network or component failures can result in loss of communication with LanProbe.

The Out-of-Band serial connection can be used as the primary means of communication or as a backup link in case of a network failure. The disadvantage of using only the Out-of-Band connection is that it is a slower means of communications.

Connecting to the Network (In-Band)

You can connect LanProbe to the network by connecting the 10Base-T (RJ-45) port. Figure 3-13 on page 38 shows the rear panel of LanProbe.

Do not touch the probe connector pins or the cable connector pins. Static discharge may damage equipment.
