Cooling / Temperature Sensing
CAUTION:
1) There must be at least 3 U free ventilation space below and above the node!
2) Make sure that all empty slots are covered with cover plates, see Table 2.
The Dragon PTN Nodes have a rugged industrial design and operate, except for the 9-L3A-L
IFM (see Ref.[6] in Table 1), entirely fanless (no moving parts). The cooling in the Dragon
PTN nodes occurs via natural convection. For this reason no other equipment can be in-
stalled directly above or below the Dragon PTN node.
Each IFM or CSM hosts several temperature sensors which can be read out via HiProvision.
When a temperature sensor goes beyond its allowed temperature range, an appropriate
temperature alarm will be triggered via HiProvision.
