DC Power System
A DC-powered Cisco NCS 6000 FCC contains four DC power trays that are part of the FCC power enclosure
(
). The upper two power trays (PT0 and PT1) are
referred to as power shelf 0 (PS0), and the lower two power trays (PT2 and PT3) are referred to as power
shelf 1 (PS1).
Figure 3: Cisco NCS 6000 FCC Slot Numbers
. Each set of power trays has a power control
module (PCM) with its own I/O power switch.
The DC power tray has four slots for PMs. The DC power trays are field-replaceable (after power down),
however the PMs are hot-swappable.
For N+N redundancy,
“
A
”
power feeds must power the upper two DC power trays and
“
B
”
power feeds must
power the lower two DC power trays (not all of the PM bays need to be filled). This allows the system to
balance its load across the two set of power trays and across the power modules within each tray.
The following table lists the DC input current and voltage specifications.
