Hot Swapping The HP 5400 zl Switch supports “hot swapping” - the ability to replace the

following hardware components while the switch is operating: a fan tray,

power supply (if a second power supply is installed), interface module.

The Management module and its components are not hot swappable.

The hot swapping feature allows you to remove or install modules without

powering off or rebooting the switch. Swapped-in modules are recognized by

the switch and begin functioning immediately after they are installed.

Caution The HP E5400 zl Switch and its components are sensitive to static discharge.

Use an antistatic wrist strap and observe all static precautions when hot

swapping components. For example, connect your antistatic wrist strap to the

ground point on the front of the switch, above the rightmost power supply bay.

WARNING This unit may have more than one power supply cable. To fully power

down the switch, you must disconnect all power supply cables from the

unit.
