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

ItemSpecifications

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 45 on page 111 lists the power specifications for the 2000 W DC power supply used
	in EX8208 switches.
