Connect AC Power to an ACX7100-32C Router

 

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.

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) damage (see Prevention of Electrostatic Discharge Damage).

  • 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.

Note

You must connect each PSM to a dedicated power source outlet.

To connect AC power to an ACX7100-32C router:

  1. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end of the strap to the ESD point on the chassis.
  2. Power off the AC input appliance inlet on the source power supply.
  3. Connect the power cord to the power source outlet.Note

    Each power supply must be connected to a dedicated AC power feed and a dedicated customer-site 2-pole circuit breaker. We recommend that you use a dedicated customer-site circuit breaker rated for 20 A (110 VAC) or 16 A (220 VAC) minimum, or as required by local code.

  4. Push the end of the AC power cord retainer strip into the hole next to the inlet on the power supply faceplate on the router until it snaps into place. Ensure that the loop in the retainer strip faces toward the power cord (see Figure 1).

  5. Press the small tab on the retainer strip to loosen the loop. Slide the loop until you have enough space to insert the power cord coupler into the inlet.
  6. Insert the power cord coupler firmly into the inlet.
  7. Slide the loop toward the PSM until it is snug against the base of the coupler.
  8. Press the tab on the loop and draw out the loop into a tight circle (see Figure 2).
  9. Route the power cord appropriately. Verify that the power cord does not block the air exhaust and access to router components, or drape where people could trip over it.
  10. Power on the source power supply.
  11. Repeat Step 3 through Step 9 for the installing the remaining PSM.
