Why did my connection to Dell iDRAC6 devices (Dell
PowerEdge Servers) fail, when the network connection
status is Connected?
Possible Cause: Dell iDRAC6 devices are limited to three concurrent connection sessions, and you have
reached the limit. There are various reasons that may cause the session to be occupied for a while until it
is relinquished—for example, you used incorrect credential information to connect with Dell iDRAC6
devices for three times or more within a short period.
Resolution: Wait one minute or more for Dell iDRAC6 devices to release the connection sessions, then
try again.
Why can’t Power Center receive events sent from
devices?
Possible Cause: Power Center is not the destination host of the events sent from devices.
Resolution: Make sure the Power Center server’s IP address is registered on the device as the destination
for events.
Possible Cause: There is a network connection problem.
Resolution: Make sure the device network and the Power Center server are connected and packets can
be routed.
Possible Cause: Essential services are not started.
Resolution: Make sure that if the Windows SNMP trap service is installed on the Power Center server, this
service and the Dell OpenManage Power Center SNMP Dispatcher are started on the Power Center
server.
Why are previously-existing power policies (including
EPR) still effective on devices when Power Center is
corrupted or has been uninstalled?
Possible Cause: Even if Power Center is corrupted or uninstalled, the Power Cap Values of existing power
policies (including EPR) on the devices still remain effective.
Resolution:
NOTE: Check your data center power capacity to avoid tripping the breaker before performing the
following steps.
• If you intend to uninstall Power Center, make sure to remove all devices first.
• If Power Center is corrupted, do one of the following to remove the power policies:
– If the device number is small, access the Dell iDRAC management console, and manually remove
the power policies.
