Connect AC Power to an EX4400 Switch
Before you connect AC power to the switch:
• Ensure that you have a power cord appropriate for your geographical locaon available.
• Ensure that you have the power cord retainer shipped with the switch.
• Ensure that you have taken the necessary precauons to prevent electrostac discharge (ESD)
damage (see Prevenon of Electrostac Discharge Damage ).
• Ensure that you have an ESD grounding strap (not provided).
• Ensure that you have connected the switch chassis to earth ground.
CAUTION: Before you connect power to the switch, a licensed electrician must aach
a cable lug to the grounding cable that you supply. A cable with an incorrectly aached
lug can damage the switch (for example, by causing a short circuit).
