CAUTION
The Fast Ethernet Interface Module and the host module are
sensitive to static discharges. Use an antistatic wrist strap and
observe all static precautions during this procedure. Failure to
do so could damage the Fast Ethernet Interface Module or the
host module.
!
CAUTION
The FE-100F3 uses Class 1 lasers. Do not use optical
instruments to view the laser output. The use of optical
instruments to view laser output increases eye hazard. When
viewing the output optical port, power must be removed from
the network adapter.
TIP
When installing Fast Ethernet Interface Modules in both port
slots 25 and 26, remove the coverplates from both slot
openings. In the following instructions, the optional module is
shown being installed in port slot 26.
