static-sensitive devices"
Observe good housekeeping in the area where you are working. Place removed covers and
other parts in a safe place.
Blue on a component indicates touch points, where you can grip the component to remove it
from or install it in the compute node or chassis, open or close a latch, and so on.
Orange on a component or an orange label on or near a component on the switch, compute
node, or chassis indicates that the component can be hot-swapped, which means that if the
chassis and operating system support hot-swap capability, you can remove or install the
component while the chassis is running. (Orange can also indicate touch points on hot-swap
components.) See the instructions for removing or installing a specific hot-swap component for
any additional procedures that you might have to perform before you remove or install the
component.
You do not have to turn off the chassis to install or replace any of the hot-swap modules on the
front or rear of the chassis.
When you install a switch in the chassis, you must also install a compatible network adapter in
the compute node to support the switch.
When you are finished working on the compute node or chassis, reinstall all safety shields,
guards, labels, and ground wires.
Each of the switch bays at the rear of the chassis contains either a switch or a filler blade.
A removed hot-swap module is replaced with an identical module or filler module within
60 seconds of removal.
