Safety Notes
RTM Malfunctioning
Incorrect RTM installation and removal can result in RTM malfunctioning.
When plugging the RTM in or removing it, do not press on the face plate but use the handles.
RTM Damage
Installing the RTM with other blades than the ones designed for it may damage the RTM and
the front blade.
Only install the RTM with the correct front blade.
Data Loss
Removing the RTM with the system power on and the blue LED on the front blade still flashing
causes data loss.
Before removing the RTM from a powered system, power down the slot by opening the right
handle of the front blade and wait until the blue LED is permanently on.
Blade Malfunctioning
Incorrect blade installation and removal can result in blade malfunctioning.
Make sure that the blade is connected to the system backplane via all assembled connectors
and that power is available on all zone 1 power pins.
Operation
System Overheating
Cooling Vents
Improper cooling can lead to blade and system damage and may void the manufacturer's
warranty.
To ensure proper cooling and undisturbed airflow through the system always operate the
system in a horizontal position. Do not obstruct the ventilation openings at the front and rear
of the system. Keep the fresh air intake at the bottom-front side of the chassis completely clear.
Make sure that the fresh air supply is not mixed with hot exhaust from other devices. Make sure
that all slots are populated with either blades, filler blades, or dummy blades.
