the DIMM.
Installing the Optional Inline Power Supply
The inline power supply option for the Cisco 1800 series fixed-configuration routers includes an inline
power supply card that must be installed inside the router, and an external power supply. Perform the
following steps to install the inline power supply card. See
Figure 7-2
for the locations of connectors
and other components within the router.
Warning
Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if
interconnections are made using uninsulated exposed metal contacts, conductors, or terminals.
Avoid using such interconnection methods, unless the exposed metal parts are located within a
restricted access location and users and service people who are authorized within the restricted
access location are made aware of the hazard. A restricted access area can be accessed only through
the use of a special tool, lock and key or other means of security.
