DC Power Specifications for EX8200 Switches

Table 1 lists the power specifications for the 3000 W DC power supply used in EX8216 switches.

Table 1: Power Specifications for a 3000 W DC Power Supply Used in an EX8216 Switch

Item	Specifications
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 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 current rating	75 A maximum at nominal operating voltage (–48 VDC) for each input terminal.
Output power	3000 W
Internal Fuse Protection	100 A

Table 2 lists the power specifications for the 2000 W DC power supply used in EX8208 switches.
