This may come in handy... i Use tables to gather these... then you may need to edit or check the RowID's you want (http://thwack.solarwinds.com/ideas/3430)
5K & 2K (5xxx and the FEX'es) info comes in with these tables.
Physical Info : 1.3.6.1.2.1.47.1.1.1.1.2
Serial # (if applicable) : 1.3.6.1.2.1.47.1.1.1.1.11
Power Status : 1.3.6.1.4.1.9.9.117.1.1.2.1.2 (Does the entity have power for Power Supplies and other items)
Operational Status : 1.3.6.1.4.1.9.9.117.1.2.1.1.2 Module has power (from above), but is it Operational ?
Fan Status : 1.3.6.1.4.1.9.9.117.1.4.1.1.1 This will supply you the status of your Fan's and PS Fan's
For all of the above, Different Row ID's are used for different entities, Fans, PS'es, Module's, and not each Row will give you an Actual Power Status... and beyond that only Modules will give you the operational status... so you either make several Custom Table Polller Charts with the same pollers and different row ID... or put it all into one and remember there will be a few gaps... (once you get rid of the empty rows [as in no status] it is a lot cleaner and easy to read).
To get 7K Module Data use these (edit and pick out the Row ID's of each thousand. 1K, 2K, 3K, etc.)
Physical Info : 1.3.6.1.2.1.47.1.1.1.1.2
Status : 1.3.6.1.4.1.9.9.91.1.1.1.1.4 --- 2nd review.. this may not be the status that you really need here. I will continue to look into this.
