    What is stated above for all products are maximum usage numbers - under full Switch and PoE load at the stated power source voltages - that should be used when sizing HVAC, Power, and UPS for switch infrastructure. In the event that information sources disagree, for the stated purpose this document should be given preference over an Installation Guide, which should be given preference over the MTBF Page, which should be given preference over a Datasheet (B5/C5).

    These specifications assume the RPS is in standby mode. When providing external power in replacement of a switch internal power supply, the RPS power specs should be computed the same as those of the internal power supply it is replacing, as outlined in the above switch tables.
