Before you remove a power supply from a ACX5000 router, ensure that you have taken
the necessary precautions to prevent electrostatic discharge (ESD) damage (see
Prevention of Electrostatic Discharge Damage ).
Ensure that you have the following parts and tools available to remove a power supply
from a ACX5000 router:
• ESD grounding strap
• Antistatic bag or an antistatic mat
•
Phillips (+) screwdriver, number 2 (DC power supply)
CAUTION: Replace the power supply with a new power supply within 1 minute
of removal to prevent chassis overheating.
To remove a power supply from an ACX5000 router (see Figure 50 on page 140 and
Figure 51 on page 140 ):
1.
Place the antistatic bag or the antistatic mat on a flat, stable surface.
2.
Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD
point on the chassis.
NOTE: If only one power supply is installed in your ACX5000 router, you
need to power off the router before removing the power supply. See
“Powering Off an ACX5000 Router” on page 129 .
3.
Disconnect power to the router:
• AC power supply—If the AC power source outlet has a power switch, set it to the
OFF (
O ) position. If the AC power source outlet does not have a power switch, gently
pull out the male end of the power cord connected to the power source outlet.
•
DC power supply—Switch the circuit breaker on the panel board that services the
DC circuit to the OFF position.
4.
Remove the power source cable from the power supply faceplate:
•
AC power supply—Remove the power cord from the power supply faceplate by
detaching the power cord retainer and gently pulling out the female end of the
power cord connected to the power supply faceplate.
•
DC power supply—Remove the screws securing the ring lugs attached to the power
source cables to the power supply using the screwdriver, and remove the power
source cables from the power supply. Replace the screws on the terminals and
tighten them.
5.
Slide the locking lever toward the handle until it stops.
6.
Grasp the power supply handle and pull firmly to slide the power supply halfway out
of the chassis.
