Connect Ac Power To An Acx7100-32C Router - Juniper ACX7100-32C Hardware Manual

1. Verify that a licensed electrician has attached the cable lug provided with the router to the grounding
cable.
2. Ensure that all grounding surfaces are clean and brought to a bright finish before grounding
connections are made.
3. Connect the grounding cable to a proper earth ground.
4. Place the grounding cable lug over the protective earthing terminal on the DC PSM.
5. Secure the grounding cable lug with the #10-32 screw.
6. Dress the grounding cable and verify that it does not touch or block access to router components,
and that it does not drape where people could trip over it.

Connect AC Power to an ACX7100-32C Router

Ensure that you have a power cord appropriate for your geographical location available to connect AC
power to the router.
Before you begin connecting AC power to the router:
• Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD)
Prevention of Electrostatic Discharge Damage
damage (see
• Ensure that you have connected the router chassis to earth ground.
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).
To meet safety and electromagnetic interference (EMI) requirements and to ensure
proper operation, you must connect the chassis to earth ground before you connect it
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 the earth
ground. The router gains additional grounding when you plug the PSM in the router to
a grounded AC power outlet by using the AC power cord appropriate for your
geographical location.
• Install the PSM in the chassis.
The power supply module (PSM) in an ACX7100-32C router is a hot-removable and hot-insertable field-
replaceable unit (FRU). You can remove and replace it without powering off the router or disrupting
routing functions.
