AC/DC Power Redundancy
The APEX1000 supports up to two dual hot-swappable redundant load sharing power
supplies (the system can operate with either one or two); supports two AC, two DC, or
one AC or one DC. In redundant mode, each power supply must be connected to an
independent power source that is attached to a dedicated circuit breaker. This circuit
breaker must comply with local building and electrical safety codes.
CAUTION
Before removing and replacing a PS unit, certify that the APEX1000 is in full redundancy;
operating in non-redundant power will require a complete system shutdown while
removing and inserting a power supply module.

3. Depress locking tab located on the lower left of the unit, as shown in the figure
