Installation/Removal
of a SIC/MIM/FIC

WARNING: H3C MSR 20/30 Series Routers do not support online insertion and
removal of SICs and MIMs. Before implementing any of the following operations,
wear an anti-static wrist strap and ESD-preventive glove, and make sure that the
power of the Router has been turned off and the power cord has been
unplugged. Otherwise, you may get an electric shock or your router may get
damaged.

CAUTION: When replacing/installing an interface card or module, note the
following

■

Do not damage the EMI gaskets on the card/module panel. They can filter
electromagnetic interference of the router.

■

To protect the card or module against ESD damage, hold the card/module by
its edge and do not touch the components on the circuit board. Put the
uninstalled interface card or module on an antistatic tray.

■

If you do not install a new card or module after removing the old one, replace
the blank filter panel to keep off the dust and ensure adequate ventilation of
the router.
