• Place the desk in its permanent locaon, allowing adequate clearance for airow and maintenance,
and secure the desk 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).
