Install the EX4400 Switch

SUMMARY This topic guides you through the steps to install EX4400 switches on two post racks, four-post racks, desks, and walls.

Unpack an EX4400 Switch

We ship EX4400 switches in a cardboard carton, secured with foam packing material. The carton has an accessory compartment.

CAUTION:

EX4400 switches are maximally protected inside the shipping carton. Do not unpack the switches until you are ready to mount the switch.

To unpack the switch:

  1. Move the shipping carton to a staging area as close to the installation site as possible, but where you have enough room to remove the system components.
  2. Position the carton so that the arrows are pointing up.
  3. Open the top flaps on the shipping carton.
  4. Pull out the packing material holding the switch in place.
  5. Verify the parts received against the inventory on the label attached to the carton (see Packing List for an EX4400 Switch).
  6. Save the shipping carton and packing materials in case you need to move or ship the switch later.

Packing List for an EX4400 Switch

The switch shipment includes a packing list. Check the parts you receive with the switch against the items on the packing list. The parts shipped depend on the switch model you purchase (see EX4400 Models and Specifications).

If any part on the packing list is missing, contact your customer service representative or contact Juniper customer care from within the U.S. or Canada by telephone at 1-888-314-5822.

Mount an EX4400 Switch on Two Posts of a Rack

You can mount an EX4400 switch on a two-post rack or on two posts of a 19-in. four-post rack by using the two-post mounting kit (part number: EX-RMK) provided with the switch. (The remainder of this topic uses rack to mean rack or cabinet.)

Before you mount an EX4400 switch on two posts of a rack:

Ensure that you have the following parts and tools available:

  • Number 2 Phillips (+) screwdriver—not provided

  • Four screws to secure the mounting brackets to the rack—not provided

  • An ESD grounding strap—not provided

  • The two-post mounting kit that includes two mounting brackets and eight screws to attach the mounting brackets—provided with the switch

  • Covers for the empty extension module slot and the empty power supply slot—provided with the switch

You can also mount an EX4400 switch:

  • Flush with the front posts of a 19-in. four-post rack by using a separately orderable four-post rack mount kit.

  • In a recessed position inside a 19-in. four-post rack by using the recessed-mounting brackets provided with a separately orderable four-post rack mount kit.

  • On a desk or other level surface by using the rubber feet provided with the switch.

  • On a wall by using a separately orderable wall mount kit.

To know the part numbers for ordering the separately orderable mounting kits, see the EX4400 Switches Datasheet.

Note:

One person must be available to lift the switch while another person secures the switch to the rack.
CAUTION:

If you are mounting multiple units on a rack, mount the heaviest unit at the bottom of the rack, and then mount the other units from the bottom of the rack to the top in decreasing order of the weight of the units.

To mount an EX4400 switch on two posts of a rack:

  1. Place the switch on a flat, stable surface.
  2. Wrap and fasten one end of the ESD wrist strap around your bare wrist, and connect the other end of the strap to a site ESD point.
  3. Attach the two-post mounting brackets (provided with the switch) to the side panels of the switch chassis by using the screws to attach the brackets (provided with the switch).

    To mount the switch flush with the posts:

    1. Align the L-shaped (front) end of the mounting brackets flush with the front panel of the switch chassis.
    2. Insert the screws into the aligned holes on the chassis (see #id-mount-an-ex4400-switch-on-two-osts-of-a-rack__two-post-bracket-ex4400). Tighten the screws.
