work safely.
Orange on a component or an orange label on or near a component indicates
that the component is hot-swappable, which means that you can remove or
install the component while the JCS 1200 platform is running. (Orange can also
indicate touch points on hot-swappable components.) See the instructions for
removing or installing a specific hot-swappable component for any additional
procedures that you might have to perform before you remove or install the
component.
You do not have to disconnect the JCS 1200 platform from power to install or
replace any of the hot-swappable modules in the JCS 1200 platform. You must
shut down the operating system and power off a Routing Engine before you
remove the Routing Engine, but you do not have to shut down the JCS 1200
platform itself (see "Powering Off a JCS 1200 Routing Engine" on page 74).
Blue on a component indicates touch points where you can grip the component
to open and close a latch or where you can grab a component to remove it from
or install it into the JCS 1200 platform.
