Hot Swapping Modules - HP ProCurve 8100fl Series Installation And Getting Started Manual

I n s t a l l a t i o n
To avoid damaging modules and the backplane, be sure to insert the right type
P r e c a u t i o n s of module into the slot type designed for it. If you install a module in the wrong
slot, physical keying prevents the module from fully entering the slot.

Hot Swapping Modules

Modules can be "hot swapped", that is installed or replaced while the switch
is powered on. The procedures and conditions differ slightly, according to the
type of module. For more information, see
on page
Avoid damage from static electricity. Static electricity can severely
damage the electronic components on the modules. Follow these
procedures to avoid such damage:
• Use proper ESD grounding procedures before handling modules.
• Handle the module by its bulkhead or edges and avoid touching the
components and the circuitry on the board.
• When installing the module, equalize any static charge difference
between your body and the switch by wearing a grounding wrist strap
and attaching it to the switch's metal body, or by frequently touching
the switch's metal body.
Ensure you fully insert the modules. That is, press the module into
the slot until the bulkhead on the module is contacting or is very close to
contacting the front face of the switch chassis.
• Do not force a module into its slot. If the module does not seem
to be seating correctly, ease it back out and check alignment. Forcing
a module can damage it and the backplane. Modules are keyed so that
they cannot be fully installed in a wrong slot.
• Check for alignment. Make sure that the metal plate of the module
—not the circuit board—is between the module guides. Check both
the upper and lower guides for proper alignment.
Secure the module. Once the module is fully inserted, make sure that
you fully close the ejector levers and screw in the two retaining screws to
secure the module in place.
For safe operation, proper switch cooling, and reduction of
electromagnetic emissions, ensure that a slot cover is installed on any
unused module slot. For safety, no more than one slot should be
uncovered at a time when you install a module and while the
switch is powered on.
