M160 Internet Router Hardware Guide
1.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and
connect the strap to one of the ESD points on the chassis. Make sure the router
is attached to a proper earth ground. For more information about ESD, see
“Preventing Electrostatic Discharge Damage” on page 226.
2.
Press the power switch for the power supply (located on the circuit breaker
box) to the
OFF
(
O
) position.
NOTE:
If you are power cycling the power supply rather than shutting it off for a
time, wait at least 60 seconds after turning it off before turning it back on. If you
need to power it off again, wait for at least 60 seconds after powering it on.
3.
Shut off the power flowing to the power supply from the external power source,
so that the voltage across the leads of the power cables is 0 V. Ensure that there
is no chance that the cable leads might become active during the procedure.
4.
Loosen the thumbscrew at each corner of the power supply faceplate, using
a Phillips screwdriver if necessary.
5.
Grasp the handle or handles on the power supply faceplate and pull firmly
to slide the unit about halfway out of the chassis.
6.
Place one hand under the power supply to support it, then slide it completely
out of the chassis.
WARNING:
Do not touch the power connectors on the rear of the power supply (see
Figure 102). They can contain dangerous voltages.
