Status and Alarm Messages
This section lists the status and alarm messages that the PDU might display. The messages are listed in
alphabetical order, and a suggested corrective action is listed with each alarm message to help you
troubleshoot problems.
Display Message Detailed Description Corrective Action
High Module Current. The high module current
threshold has been exceeded.
Evaluate the threshold setting. If necessary,
adjust it for your situation.
High Subfeed Current. The high subfeed current
threshold has been exceeded.
Evaluate the threshold setting. If necessary,
adjust it for your situation.
Low Module Current. The low module current
threshold has been exceeded.
Evaluate the threshold setting. If necessary,
adjust it for your situation.
Low Subfeed Current. The low subfeed current
threshold has been exceeded.
Evaluate the threshold setting. If necessary,
adjust it for your situation.
Maximum Module
Current.
The maximum module current
threshold has been exceeded.
Evaluate the threshold setting. If necessary,
adjust it for your situation.
Maximum Subfeed
Current.
The maximum subfeed current
threshold has been exceeded.
Evaluate the threshold setting. If necessary,
adjust it for your situation.
Minimum Module
Current.
The minimum module current
threshold has been exceeded.
Evaluate the threshold setting. If necessary,
adjust it for your situation.
Minimum Subfeed
Current.
The minimum subfeed current
threshold has been exceeded.
Evaluate the threshold setting. If necessary,
adjust it for your situation.
Modular Distribution
Communication.
Communication has been lost
with the modular distribution
breakers.
Check the communication cables to ensure they
are properly connected. Contact APC Customer
Support.
Module Breaker Open. A modular circuit breaker is
open.
Check the modular circuit breakers to see if one
has overloaded. Replace if necessary.
Subfeed Breaker Open. A subfeed circuit breaker is
open.
Check the subfeed circuit breakers to see if one
has been over-loaded.
