DC Power Specifications for EX 8200 series Switches

Table 1 lists the power specifications for the DC power supply used in EX 8200 series switches.

Table 1: Power Specifications for a 3000 W DC Power Supply Used in an EX 8216 Switch



DC input voltage

  • Minimum operating voltage: –40 VDC
  • Nominal operating voltage: –48 VDC
  • Operating voltage range: –40 VDC through –72 VDC

Note: If the input voltage from the DC power source drops below -37.5 through -39.5 VDC, the switching platform automatically shuts down. During automatic shutdown, the circuit remains active. When the input voltage returns to –43 through –44 VDC, the switch automatically starts up again and the system returns to normal operation within 30 minutes. No operator intervention is required.

DC input current rating

100 A maximum at nominal operating voltage (–48 VDC) for each input terminal.

Output power

3000 W

Internal Fuse Protection

100 A
