ensure opmal cooling for the switch.
Mount an EX4400 Switch in a Recessed Posion in a Rack or Cabinet
You can mount an EX4400 switch in a recessed posion inside a 19-in. four-post rack by using the
recessed-mounng brackets provided with a separately orderable four-post rack mount kit (part number:
EX-4PST-RMK). (The remainder of this topic uses rack to mean rack or cabinet.)
Before you mount an EX4400 switch in a recessed posion inside a 19-in. four-post rack:
• Verify that the site meets the requirements described in "Site Preparaon Checklist for EX4400
Switches" on page 115.
• Place the rack in its permanent locaon, allowing adequate clearance for airow and maintenance,
and secure the rack to the building structure.
• Read Juniper Networks Safety Guide, with parcular aenon to Chassis and Component Liing
Guidelines.
• Ensure that you have taken the necessary precauons to prevent electrostac discharge (ESD)
damage (see Prevenon of Electrostac Discharge Damage).
• Remove the switch from the shipping carton (see "Unpack an EX4400 Switch" on page 143).
