C H A P T E R 1 Intel Express 550T Routing Switch
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
circuit board If you remove the plate covering the slot on the front of the switch,
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 1M
Ω
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 (following the instructions in the
module’s User Guide). 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.
