Unpacking and Mounting the EX4300 Switch

Unpacking an EX4300 Switch

EX4300 switches are shipped in a cardboard carton, secured with foam packing material. The carton has an accessory compartment.

CAUTION:

EX4300 switches are maximally protected inside the shipping carton. Do not unpack the switches until you are ready to begin installation.

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 Parts Inventory (Packing List) for an EX4300 Switch.
  6. Save the shipping carton and packing materials in case you need to move or ship the switch later.

You can mount the switch on four posts of a four-post rack by using the mounting brackets provided with the separately orderable four-post rack-mount kit. See Mounting an EX4300 Switch on Four Posts of a Rack or Cabinet.

Note:

If you need to mount the switch in a recessed position on two posts of either a two-post rack or a four-post rack, you can use the 2-in.-recess front-mounting brackets provided in the separately orderable four-post rack-mount kit.

Note:

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

CAUTION:

If you are mounting multiple switches on a rack, mount a switch in the bottom of the rack first and proceed to mount the rest of the switches from bottom to top.

To mount the switch on two posts of a rack:

  1. Place the switch on a flat, stable surface.
  2. Align the mounting brackets along the front, rear, or center of the side panels of the switch chassis depending on how you want to mount the switch. For example, if you want to front-mount EX4300 switches except EX4300-48MP and EX4300-48MP-S switches, align the brackets along the front of the side panel (see Figure 1). If you want to front-mount an EX4300-48MP or EX4300-48MP-S switch, align the brackets 17.5 mm offset from the front panel (see Figure 2 and Figure 3).

You can mount the switch on two posts of either a two-post rack or a four-post rack by using the mounting brackets provided with the switch. See Mounting an EX4300 Switch on Two Posts of a Rack or Cabinet.

Note:

If you need to mount the switch in a recessed position on either a two-post rack or a four-post rack, you can use the 2-in.-recess front-mounting brackets provided in the separately orderable four-post rack-mount kit.

Note:

To ensure that the protective earthing terminal is accessible through the opening in the rear mounting-blade:

  • Ensure that the rack is 27.5 in. (70 cm) through 30.5 in. (77.5 cm) deep if you are mounting the switch flush with the rack front on four posts of a rack.

  • Ensure that the rack is 29.5 in. (75 cm) through 32.5 in. (82.5 cm) deep if you will mount the switch 2 in. recessed from the rack front.

Note:

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

CAUTION:

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

To mount the switch on four posts of a rack:

  1. Place the switch on a flat, stable surface.
    Note:

    The four-post rack-mount kit ships with the short front-mounting brackets attached to the side mounting-rails. If you want to recess the switch in the rack, you must unscrew the short front-mounting brackets from the side mounting-rails by using the Phillips (+) screwdriver and attach the long front-mounting brackets to the side mounting-rails.

  2. Align the side mounting-rails along the side panels of the switch chassis. Align the two holes in the rear of the side mounting-rails with the two holes on the rear of the side panels.
  3. Insert 4x6-mm Phillips flat-head mounting screws into the two aligned holes and tighten the screws by using the screwdriver. Ensure that the remaining four holes in the side mounting-rails are aligned with the four holes in the side panel. See Figure 5.

Mounting an EX4300 Switch in a Recessed Position in a Rack or Cabinet

You can mount an EX4300 switch in a recessed position on two posts of either a two-post rack or a four-post rack such that the switch is recessed inside the rack from the rack front by 2 inches. To mount the switch in a recessed position, use the front-mounting brackets provided in the separately orderable four-post rack-mount kit.

Reasons to mount the switch in a recessed position include:

  • You are mounting the switch in a cabinet and the cabinet doors do not close completely unless the switch is recessed.

  • The switch you are mounting has an uplink module with transceivers installed in it—the transceivers in the uplink module ports protrude from the front of the switch.

To mount the switch in a recessed position, on two-posts or on four-posts, follow the instructions in Mounting an EX4300 Switch on Two Posts of a Rack or Cabinet or Mounting an EX4300 Switch on Four Posts of a Rack or Cabinet.

Mounting an EX4300 Switch on a Wall

Before mounting the switch on a wall:

Ensure that you have the following parts and tools available:

  • Phillips (+) screwdriver, number 2 (not provided)

  • 2 wall-mount brackets (provided with the wall-mount kit)

  • 12 wall-mount bracket screws (provided with the wall-mount kit)

  • 4 mounting screws (8-32 x 1.25 in. or M4 x 30 mm) (not provided)

  • Cover panels for uplink module and power supply slots (provided)

  • Hollow wall anchors capable of supporting the combined weight of two fully loaded switches, up to 33 lb (15 kg) (not included)—if you are mounting the switch in sheetrock (wall board with a gypsum plaster core) or in wall board not backed by wall studs.

Warning:

When mounting EX4300 switches except EX4300-48MP and EX4300-48MP-S switches on a wall, orient the front panel of the chassis downward to ensure proper airflow and meet safety requirements in the event of a fire. When mounting EX4300-48MP and EX4300-48MP-S switches on a wall, orient the front panel of the chassis pointing to the right side or to the left side to ensure proper airflow and meet safety requirements in the event of a fire.

Note:

For easier lifting, install any additional power supplies only after you mount the switch on the wall.

You can mount an EX4300 switch on a wall by using the separately orderable wall-mount kit.

To mount the switch on a wall:

  1. Attach the wall-mount brackets to the sides of the chassis by using four of the wall-mount bracket screws on each side (see the representation in Figure 8). Use the screwdriver to tighten the screws.
    Figure 8: Attaching Wall-Mount Brackets to the Switch ChassisAttaching Wall-Mount Brackets to the Switch Chassis
  2. If you are mounting two switches together, line the second switch on top of the first and attach it to the mounting brackets by using two wall-mount bracket screws on each side (see the representation in Figure 9).
  3. Insert the mounting screws in the wall. If you are mounting EX4300 switches except EX4300-48MP and EX4300-48MP-S switches, insert the top pair of mounting screws 474.35 mm apart, and insert the second pair of mounting screws 151.81 mm directly below the first set. If you are mounting EX4300-48MP and EX4300-48MP-S switches, insert the top pair of mounting screws 474.2 mm apart, and insert the second pair of mounting screws 152 mm directly below the first set (see Figure 10 and Figure 11).

    If the mounting screws are inserted in a wall board with no stud behind it, you must use dry wall anchors rated to support 75 lb (34 kg). Insert the screws into wall studs wherever possible to provide added support for the chassis.

    Drive the screws only part way in, leaving about 1/4 in. (6 mm) distance between the head of the screw and the wall. Use the screwdriver to drive the screws in.

  4. Grasp each side of the switch or switches, lift the switch or switches, and hang the brackets from the mounting screws (see the representation in Figure 9).
