Install the MX304 Router in a Four-Post Rack

Here's how to install the router in a four-post rack or a cabinet:

Note:

The four-post mounting kit (JNP304-4PST-RMK) is included with the MX304. If the four-post kit is lost, you can order a replacement.

Note:

The four-post mounting bracket that is shipped preinstalled on the MX304 chassis is not part of the four-post mounting kit (JNP304-4PST-RMK). If the four-post mounting bracket is damaged or lost, contact customer support for repair or replacement. See Contact Customer Support and Returning the Chassis or Components.
CAUTION:

If you're installing more than one router in a rack, install them from the bottom up.

CAUTION:

Before front-mounting the router in a rack, have a qualified technician verify that the rack is strong enough to support the router's weight and is adequately supported at the installation site.
CAUTION:

Lifting the chassis and mounting it in a rack requires two people (one person to hold the router in place and a second person to install the screws). A fully loaded AC-powered, DC-powered, HVAC/DC-powered router weighs up to 70.54 lb (32 kg).
  1. Position the router in front of the four-post rack or the cabinet.
  2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and to a site ESD point.
  3. (Optional) Install the cable management brackets on each side of the front of the four-post mounting brackets, and secure each cable management bracket with screws at the bottom and top of the bracket as shown below:
    Figure 1: Install the Cable Manager Install the Cable Manager
  4. With one person holding on to each side of the chassis, carefully lift the bottom of the chassis so that four-post mounting brackets (with optional cable management brackets) contact the rack rails.
  5. Attach the chassis to the front of the rack as shown below: Figure 2.

  6. On the rear of the chassis, slide the rear-mounting brackets on both sides of the chassis until they contact the rack rails. Starting from the bottom of the rack, insert the mounting screws through the mounting brackets and mounting holes on the rack and tighten them. See Figure 3.

  7. Verify that the mounting screws on each side of the rack are aligned and the router is level.

Install the MX304 Router in a Two-Post Rack

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

Note:

The two-post mounting kit is not included with the chassis. You can order the two-post mounting kit (JNP304-2PST-RMK) seperately.
CAUTION:

If you are installing more than one router in a rack, install the lowest one first.

CAUTION:

Before front-mounting the router in a rack, have a qualified technician verify that the rack is strong enough to support the router's weight and is adequately supported at the installation site.
CAUTION:

Lifting the chassis and mounting it in a rack requires two people (one person to guide the router in place and a second person to install the screws). A fully loaded AC-powered, DC-powered, HVAC/DC-powered router weighs up to 70.54 lb (32 kg).
  1. Position the router in front of the two-post rack or the cabinet.
  2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and to a site ESD point.
  3. Remove the four-post mounting bracket that is preinstalled on the chassis. See Figure 6.
    Figure 6: Remove the Preinstalled Four-Post Mounting Bracket Juniper Networks device being mounted into a rack with front panel ports, indicators, and rack-mounting brackets shown.
  4. Align the holes in the two-post mounting bracket with the screw holes on the side of the chassis. Attach the two-post mounting bracket to the device by using the mounting screws. Tighten the screws. See Figure 7.
    Figure 7: Attach the 2-Post Mounting Brackets Juniper Networks device mounted in rack showing front panel with ports and connectors and dashed lines for screw placement.
  5. Repeat the steps on the opposite side of the device.
  6. Install the cable management brackets on each side of the chassis, and secure each bracket with screws at the bottom and top of the bracket.
    Figure 8: Attach the Cable Manager Juniper Networks device front panel with network ports and rack-mounting brackets highlighted for installation.
  7. Have one person grasp both sides of the device, lift it, and position it in the rack so that the two-post mid-bracket aligns with the rack holes.
  8. Have a second person secure the two-post mounting bracket to the rack by using four mounting screws (and cage nuts and washers if your rack requires them. Tighten the screws. See Figure 9.
