• One ferrite
• One RJ-45-to-DB-9 console port adapter cable
Note To connect the switch functional ground, you need a ring terminal lug (such as
Thomas & Bett part number RC10-14 or equivalent).
If you want to connect a terminal to the switch console port, you need to provide
an RJ-45-to-DB-25 female DTE adapter. You can order a kit (part number
ACS-DSBUASYN=) with that adapter from Cisco.
For multimode (MM) connections, you can connect a 100BASE-FX port to a port
on a target device by using one of the MT-RJ fiber-optic patch cables listed in
Table B-1 on page B-3. Use the Cisco part numbers in Table B-1 to order the
patch cables that you need.
For single-mode (SM) connections, you can connect a 100BASE-LX port to a port
on a target device by using one of the connectors listed in Table B-2 on page B-4.
Use the Cisco part numbers in Table B-2 to order the patch cables that you need.
Applying the Switch Protective Liner
The switch ships with a protective liner that prevents debris from falling into the
switch ventilation holes during installation. Before installing the switch on a DIN
rail or in a 19-inch rack, connecting the switch to a power source, or wiring the
external alarm device relays, you must first apply the protective liner.
Because the protective liner covers ventilation holes on the switch, the liner must
be removed from the switch before power is applied to allow proper airflow
through the switch chassis.
