Rack-mount kit

Mounting option for the EX4400

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 mount an EX4400 switch flush with the front posts of a 19-in. four-post 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:

a. Align the L-shaped (front) end of the mounting brackets flush with the front panel of the switch chassis.

b. Insert the screws into the aligned holes on the chassis. Tighten the screws.





To mount the switch along the middle of its side panels:

a. Align the L-shaped (front) end of the mounting brackets along the middle of the side panels.

b. Insert the screws into the aligned holes on the chassis. Tighten the screws.





4. Decide which end of the switch you want to place at the front of the rack. Position the switch so that the AIR IN labels on the fan modules are next to the cold aisle and the AIR OUT labels on the fan modules are next to the hot aisle.

5. Have one person grasp both sides of the switch, lift the switch, and position it in the rack, aligning the holes of the mounting brackets with the threaded holes in the front post of the rack. Align the bottom hole in both the mounting brackets with a hole in each rack rail, making sure that the chassis is level.

6. Have a second person secure the mounting brackets to the rack by using four screws appropriate for your rack. Tighten the screws.





7. Ensure that the switch chassis is level by verifying that all screws on one side of the rack are aligned with the screws on the other side.

8. Cover the empty extension module slot and empty power supply slot by using the covers that came 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 two-post rack or on two posts of a 19-in. four-post rack by using the two-post mounting brackets and screws provided with the switch.

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


To mount an EX4400 switch flush with the front posts of a 19-in. four-post 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 wall mount brackets to the sides of the chassis by using four of the wall mount bracket screws on each side. Use the screwdriver to tighten the screws.





4. Insert the four mounting screws in the wall. Insert the top pair of mounting screws 15.2 cm apart, and insert the second pair of mounting screw 47.42 cm directly below the first set. If the mounting screws are inserted in a wall board with no stud behind it, you must use dry wall anchors rated to support 66 lb (30 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.





5. Grasp each side of the switch or switches, lift the switch or switches, and hang the brackets from the mounting screws
