Adding and Removing SFM Modules
Using the Grounding Wrist Strap and Chassis Grounding Lug
Because electrostatic discharge (ESD) can damage switch components such as the Switch Fabric Modules,
you must always ground yourself properly before removing or adding a module. For this purpose, Alcatel
provides a grounding wrist strap and a grounding lug located near the bottom-right of the chassis. To prop-
erly ground yourself, follow the steps below.
1
Fasten the grounding strap to your wrist. (A grounding strap was provided in your OmniSwitch 8800
series ship kit.)
2
Insert the wrist strap’s connector pin (located at the end of the strap’s tether) into the grounding lug
near the bottom-right of the chassis.
Note.
For the grounding wrist strap to be effective in eliminating ESD, power supplies must be installed in
the chassis and plugged into grounded AC outlets.
