DC Power Specifications for EX8200 Switches
Table 44 on page 110 lists the power specifications for the 3000 W DC power supply used
in EX8216 switches.
Table 44: Power Specifications for a 3000 W DC Power Supply Used in an EX8216 Switch
Specifications Item
• 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 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.
DC input voltage
75 A maximum at nominal operating voltage (–48 VDC) for each input terminal. DC input current rating
3000 W Output power
100 A Internal Fuse Protection
