WARNING: Before performing DC power procedures, ensure that power is removed from the DC
circuit. To ensure that all power is off, locate the circuit breaker on the panel board that services the
DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit
breaker in the OFF position.
CAUTION: Before you connect power to the router, a licensed electrician must attach a cable lug to
the grounding and power cables that you supply. A cable with an incorrectly attached lug can damage
the router (for example, by causing a short circuit).
CAUTION: To meet safety and electromagnetic interference (EMI) requirements and to ensure proper
operation, you must connect MX10016 router to earth ground before you connect them to power.
For installations that require a separate grounding conductor to the chassis, use the protective earthing
terminal on the router chassis to connect to earth ground. For instructions on connecting an MX10016
router to ground using a separate grounding conductor, see “Ground the Chassis” on page 17.
2. Ensure that you have the following parts and tools available to install a DC power supply in an MX10016:
•
Electrostatic discharge (ESD) grounding strap
•
DC power source cables (not provided) with the cable lugs (provided) attached
The provided terminal lugs in an MX10016 are sized for 4 AWG (21.1 mm
2
) power source cables. The DC power
source cables that you provide must be 4 AWG (21.1 mm
2
), minimum 60°C wire. We recommend that you install
heat-shrink tubing insulation around the crimped section of the power cables and lugs.
•
13/32 in. (10 mm) nut driver or socket wrench
•
Phillips (+) screwdrivers, numbers 1 and 2
•
Multimeter
To install a DC power supply in an MX10016 (see Figure 22):
1. Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point
on the chassis. There is an ESD point located next to the protective earthing terminal and below PSU 9 on the rear
panel .
2. Taking care not to touch power supply components, pins, leads, or solder connections, remove the power supply from
its bag.
3. Peel back and remove the protective plastic wrap that covers all four sides of the power supply.
4. Ensure the power switch is set to the standby (O) position. This switch turns off the output voltage; it does not interrupt
DC.
