v Handle carriers by available handles or edges only; avoid touching the
printed circuit boards or connectors.
v
Place a removed component board-side-up on an antistatic surface or in a
static shielding container. If you plan to return the component to the
factory, immediately place it in a static shielding container.
v Never attempt to remove the printed circuit board from the metal carrier.
CAUTION:
For safety reasons, check the resistance value of the antistatic strap
periodically. The measurement should be between 1 and 10 megohm
(Mohm).

Note:
Invisible laser radiation may be emitted from disconnected fibers or
connectors. Do not stare into beams or view directly with optical instruments.
Note: Use of controls, adjustments, or performing procedures other than those
specified may result in hazardous radiation exposure.
Note: Hazardous voltage or energy is present on the backplane when the system is
operating. Use caution when servicing.
CAUTION:
To prevent ESD damage, wear grounding wrist straps during these procedures
and handle modules by the carrier edges only.
CAUTION:
Make sure that you do not accidentally press one or more of the ejector release
buttons on a switching, supervisor, and fabric modules. These buttons and their
mechanical levers are designed so that you can easily power down and remove
these modules when you need to replace them. If you press one of these
buttons, the lever for that button releases from the front of the module, but the
module remains operational and connected to the system. If you press the other
ejector button on the same module at the same time as you press the first button
or while the lever for the first button is released, the lever for the second button
releases, and the module powers down and disconnects from the system.
This behavior can be disabled with the no hardware ejector enable command. To
minimize the chance of accidentally disconnecting a module with a released lever,
press the lever back toward the module until it clicks. If both levers are released,
the system has disconnected and powered down the module, and the STATUS LED
will be unlit. To reconnect and power up the module, either remove and reinsert
