When installing DC power supply, use 20 AWG, 90°C wires. Always ensure that the building's installation
for short-circuit (overcurrent) protection does not exceed 15A.
Note
A circuit breaker of maximum 15 A should be used.
Warning
A readily accessible two-poled disconnect device must be incorporated in the fixed wiring. Statement 1022
Note
This equipment is suitable for installation in Network Telecommunications Facilities and locations where the
NEC applies. The equipment is suitable for installation as part of the Common Bonding Network (CBN).
Warning
Connect the unit only to DC power source that complies with the safety extra-low voltage (SELV) requirements
in IEC 60950 based safety standards. Statement 1033
Caution The grounding architecture of this product is DC-isolated (DC-I) for DC-powered products. DC-powered
products have a nominal operating DC voltage of -48 VDC.
Power On the Router
After the router is rack mounted, perform these tasks to complete the installation:
• Power on the router.
• Connect the front-panel ports. See the Connect to SFP Modules section, to complete the installation.
