Starting the Probe
NOTE If you are using the Bootp server method of configuration, do not attach the power
cord to the probe until told to do so in “Bootp Server Configuration” on page 71.
If you used the local terminal method of configuration, attach the power cord to
the probe. The probe does not have a power switch, but is powered on when
power is attached. When powered on or reset, the probe runs self-tests and
transmits ICMP echo frames to the default gateway for the purpose of allowing
the probe to be discovered by the routers (ARP cache). The probe transmits four
ICMP echo request packets about 10 seconds after booting and again every
autodiscovery echo interval.
