	Installing a Module
Introduction	You can increase the connectivity options of your switch by installing
	a module.
	Warning Modules are not designed to be installed in, or removed
		from, the switch while it is in operation. You must
		power off the switch before attempting to install or
		remove a module.
Static-free working area	The module’s printed circuit board is an Electrostatic Sensitive De-
	vice and should be handled only in a static-free working area; other-
	wise, the printed circuit board may fail or be degraded.
Avoiding damage to the	If you remove the plate covering the slot on the front of the switch,
circuit board	for example, to install or remove a module, follow this procedure to
	avoid damage to your printed circuit board:
	Warning Do not remove the plate unless the switch is discon-
		nected from the main power supply.
	1	Disconnect the switch from the main power supply.
	2	Ground the switch before you handle the printed circuit board.
	3	Connect yourself to a non-painted/non-isolated part of the
		grounded switch (for example the back panel) using a wrist
		strap with 1MΩ resistance to ensure that you carry the same
		electrostatic charge as the enclosure.
	4	Remove the plate covering the slot.
Installing a module	To install a module:
	1	If the switch is already operational, disconnect it from the main
		power supply.
	2	Follow the instructions in “Avoiding damage to the circuit
		board” above.
	3	Unscrew the screws of the plate covering the slot on the front of
		the switch. Save these screws and plate.
	4	Insert the module into the slot. Place your thumbs just beneath
		the screws on the front panel of the module and push in the
		module. Secure it using the retaining screws.
