DC input voltage

Nominal –48 VDC, –60 VDC

Operating range: –40.0 to –72.0 VDC

Note: If the input voltage from the DC power source drops below -37.5 to -39.5 VDC, the router automatically shuts down. During automatic shutdown, the circuit remains active. When the input voltage returns to –43.0 to –44.00 VDC, the router automatically starts up again and the system returns to normal operation within 30 minutes. No operator intervention is required.
