Strain on the cable could dislodge the leads from the terminal block.
Caution
Do not use a power cable to connect the chassis low voltage DC input to a voltage source. If you

inadvertently plug a cable into a 120 Vac source, the low voltage supply will be damaged and hazard
could result.
If you need a cable to connect to the low voltage DC power supply, cut off the plug from the power cord
and hard wire the Cisco 2010 CGR low voltage DC input directly to its power source, observing the
correct polarity markings.
Stay clear of the terminal block when energy has been restored. The terminal block screw heads and any

exposed wiring could have hazardous line voltages (depending on the voltage source). The Cisco 2010
CGR is intended to be installed in a restricted access location and serviced by trained personnel only.

Shutting Off Power

Even though shutting off power to the Cisco 2010 CGR is anticipated to be infrequent, there may be
occasion to turn off the router. There is no on/off switch on the Cisco 2010 CGR. This ensures that there
will not be any accidental shutdown due to turning off a power switch; thus, guaranteeing a high
reliability in keeping the router up. To shut off power to the router, there are two options:
