protection. If backup power is required, see the “Connecting Routers to Backup Power” section on
page 9.
Note The input voltage tolerance limits for AC power are 90 and 264 VAC.
Warning
AC connected units must have a permanent ground connection in addition to the power cable ground
wire. NEBS-compliant grounding satisfies this requirement.
