Fast Track to Rack Installation and Power

This procedure guides you through the steps to install the ACX5400 router in a rack and connect it to power.

Install the ACX5400 Router in the Rack

You can install a Juniper Networks® ACX5400 router into a 19-inch four-post rack or a cabinet. We’ll walk you through the steps to install an AC-powered ACX5400 router in a 19-inch four-post rack.

Before you install, review the following:

To install the router in a four-post rack or cabinet:

  1. Position the router in front of the rack or cabinet.
  2. 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.
  3. Align the holes in the front-mounting rails with the holes on the side of the chassis (see Figure 1 for ACX5448, Figure 2 for ACX5448-D, and Figure 3 for ACX5448-M).

    Figure 3: Install the Mounting Rails on an ACX5448-M Router Install the Mounting Rails on an ACX5448-M Router
  4. Using a Phillips (+) number 2 screwdriver, secure the mounting rails to the chassis using the mounting screws.
  5. With one person on each side, hold on to the bottom of the chassis and carefully lift it so that the mounting rails contact the rack rails.
  6. Carefully slide the chassis with the rails attached on to the rack rails (see Figure 4 for the ACX5448 router, Figure 5 for the ACX5448-D router, and Figure 6 for the ACX5448-M router).

    Figure 12: Install the Rear-Mounting Blades on an ACX5448-M Router Juniper Networks switch or router being installed in a server rack with mounting brackets secured by screws; green arrow indicates alignment direction.
  9. Install mounting screws into each of the rear-mounting bracket holes aligned with the rack, starting from the bottom, and secure them tightly.
  10. Visually inspect the alignment of the chassis. If you’ve installed the chassis properly in the rack, all the mounting screws on one side of the rack are aligned with the mounting screws on the opposite side, and the router is level. Figure 13, Figure 14, and Figure 15 show the router fully secured and installed in a four-post rack.

Connect to Power

To connect the ACX5400 router to AC power, perform the following steps:

Connect Earth Ground to ACX5400 Chassis

Before you connect earth ground to the protective earthing terminal of a ACX5400 router, ensure that a licensed electrician has attached an appropriate grounding lug to the grounding cable.

Figure 16, Figure 17, and Figure 18 show the grounding points on ACX5400 routers.

Grounding points

 

You need a protective earthing terminal bracket for connecting the chassis to earth ground. This two-holed bracket attaches on the side of the chassis through the mounting rail and provides a protective earthing terminal for the router. The grounding points are in the form of studs sized for #10–32 pan head screws. (You need to provide these screws with integrated washers as we do not ship them in the accessory kit). The grounding points are spaced at 0.63-in. (16-mm) centers.

You ground the router by connecting one end of a grounding cable to earth ground and then attaching the other end to the chassis grounding points by using two #10–32 pan head screws. You must provide the grounding cables.

Note:

The grounding lug required is a Panduit LCD10-10A-L or equivalent (not provided). The grounding lug accommodates 12 AWG (2.5 mm²) stranded wire. The grounding cable that you provide for the chassis must be the same size or heavier than the input wire of each power supply. Minimum recommendations are 12 AWG (2.5 mm²) stranded wire, 60° C wire for the ACX5448 router and 12 AWG (2.5 mm²), 90° C temperature-rated stranded wire for the ACX5448-D and ACX5448-M routers.

To ground the ACX5400 router:

  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. For ACX5448-M routers, remove the dummy screws from the grounding point (see Figure 20).
  5. Place the grounding cable lug over the grounding points on the side of the chassis (see Figure 19 for ACX5448 and ACX5448-D routers and Figure 20 for the ACX5448-M router).
    Figure 19: Connect the Grounding Cable to the ACX5448 or ACX5548-D Router Connect the Grounding Cable to the ACX5448 or ACX5548-D Router
    Figure 20: Connect the Grounding Cable to the ACX5448-M Router Connect the Grounding Cable to the ACX5448-M Router
  6. Secure the grounding cable lug with the screws. The holes are sized to accommodate #10–32 pan head screws.
  7. 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 ACX5400 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) 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. Under all circumstances, 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 ACX5400 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.

Note:

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

To connect AC power to an ACX5448 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.

    Figure 21 shows the port on the AC PSM for ACX5448 router where the power cord retainer is installed.

  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 23).
  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.
