Installation
Damage of Circuits
Electrostatic discharge and incorrect RTM installation and removal can damage circuits
or shorten their life.
Before touching the RTM or electronic components, make sure that you are working in
an ESD-safe environment.
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.
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
lower handle of the front blade and wait until the blue LED is permanently ON.
RTM Damage
Installing the RTM with other blades than the PENT/ATCA-7221 damages the RTM.
Only install the RTM with the Emerson PENT/ATCA-7221 blade.
Operation
RTM damage
High humidity and condensation on the RTM surface causes short circuits.
Do not operate the RTM outside the specified environmental limits. Make sure the RTM
is completely dry and there is no moisture on any surface before applying power. Do not
operate the RTM below 0ºC.
RTM Overheating and RTM Damage
Operating the RTM without sufficient forced air cooling may lead to RTM overheating
and thus RTM damage.
When operating the RTM, make sure that sufficient forced air cooling is available in the
shelf.
When operating the RTM in areas of electromagnetic radiation ensure that the RTM is
bolted on the system and the system is shielded by enclosure.
Make sure that contacts and cables of the RTM cannot be touched while the RTM is
operating.
