When on, the breakers on the PDCA distribute power to the BPSs. Power is present at the
BPSs when:
• The amber LED labeled AC0 Present is on (if the breakers are on the PDCA on the left
side at the back of the cabinet).
• The amber LED labeled AC1 Present is on (if the breakers are on the PDCA on the right
side at the back of the cabinet).
