Specifications
2500 W AC power supply:
Low-voltage line—1250 W
High-voltage line—2500 W
5000 W AC power supply:
Both power feeds connected and active:
Low-voltage line—2500 W
High-voltage line—5000 W
Only one power feed connected and active:
Low-voltage line—1250 W
High-voltage line—2500 W
CAUTION: Mixing different types of power supplies (AC and DC or AC power
supplies of different wattage) in the same chassis is not supported.
Mixing low-voltage input line and high-voltage input line power feeds in the
same chassis is not supported.

AC Power Cord Specifications for an EX6200 Switch on page 109
EX6200 switches can use either AC or DC power supplies.
Table 48 on page 108 lists the power specifications for the 2100 W DC power supply used
in EX6200 switches.
Specifications
Nominal operating voltage: –48 VDC through - 60 VDC
Operating voltage range: –40 VDC through –72 VDC
NOTE: If the input voltage from the DC power source drops below –37.5 VDC through –39.5 VDC,
the switching platform automatically shuts down. During automatic shutdown, the circuit remains
active. When the input voltage returns to –43 VDC through –44 VDC, the switch automatically
starts up again and the system returns to normal operation within 30 minutes. No operator
intervention is required.
60 A maximum at lowest nominal operating voltage (–40 VDC) for each input terminal.
50 A maximum at nominal operating voltage (–48 VDC) for each input terminal.
