# snmpwalk -v 2c -c public -m ALL localhost SUN-HW-MONITORING-MIB::sunHwMonProductGroup
You should see output similar to the following:
SUN-HW-MONITORING-MIB::sunHwMonProductName.0 = STRING: SUN FIRE X4440
SUN-HW-MONITORING-MIB::sunHwMonProductType.0 = INTEGER: rackmount(3)
SUN-HW-MONITORING-MIB::sunHwMonProductPartNumber.0 = STRING: 602-4058-01
SUN-HW-MONITORING-MIB::sunHwMonProductSerialNumber.0 = STRING: 0823QBU01C
SUN-HW-MONITORING-MIB::sunHwMonProductManufacturer.0 = STRING: SUN MICROSYSTEMS
SUN-HW-MONITORING-MIB::sunHwMonProductSlotNumber.0 = INTEGER: -1
SUN-HW-MONITORING-MIB::sunHwMonProductUUID.0 = STRING: 080020FFFFFFFFFFFFFF00144FEDE5E0
SUN-HW-MONITORING-MIB::sunHwMonProductBiosVersion.0 = STRING: S90_3B18
sunHwMonProductSlotNumber.0 = INTEGER: -1
This is expected behavior because slot numbers are relevant only to blade servers. Rackmount servers do not have slot numbers.
