5. Click

6. To add more IT devices, repeat the same steps.
In the beginning, the status of the added IT equipment shows "Waiting for reliable connection," which means
the requested number of consecutive successful or unsuccessful pings has not reached before Legrand PDU
can declare that the monitored device is reachable or unreachable.
To check the server monitoring states and results:
1. After adding IT equipment for monitoring, all IT devices are listed on the Server Reachability page.
2. The column labeled "Ping Enabled" indicates whether the monitoring for the corresponding IT device is
activated or not.
3. The column labeled "Status" indicates the accessibility of monitored equipment.
Status
Description
Reachable

Waiting for reliable
connection
The connection between the Legrand PDU
device and the monitored equipment is not
reliably established yet.

Example: Ping Monitoring and SNMP Notifications
In this illustration, it is assumed that a significant PDU (IP address: 192.168.84.95) shall be monitored by
your Legrand PDU to make sure that PDU is properly operating all the time, and the Legrand PDU must
send out SNMP notifications (trap or inform) if that PDU is declared unreachable due to power or network
failure. The prerequisite for this example is that the power sources are different between your Legrand PDU
and the monitored PDU.
This requires the following two steps.
Step 1: Set up the ping monitoring for the target PDU
1. Choose Device Settings > Server Reachability.
