PSE Multi-Port 2nd Generation Test Suite for 802.3at
 

 

With the 2nd generation PSE Multi-Port Test Suite, PSE system evaluators can readily, that is a with a few mouse clicks, discover answers to such questions as:

 

• How does PSE power management respond tomulti-port connections of Class N PD's and how does power management respond to multi-port LLDP negotiations requesting full Class N power levels? (N= 0, 1, 2, 3, or 4)
• How much time does it take for the PSE to apply power to, and if applicable, complete LLDP power negotiation with Type-1 and/or Type-2 PD's?
• How much time does it take for the PSE to remove power given bulk PD disconnects and how much time to restore power when PD's are re-connected?
• How much continuous power can the PSE furnish to all powered (and granted) Type-1 and/or Type-2 PD's? What is the magnitude of over-allocated or under-allocated power to Type-1 and/or Type-2 PD's?
• How much power capacity is reserved for valid Type-1 and/or Type-2 PD load transients under conditions of full and 50% static power consumption?
• How predictable is PSE port overload shutdown criteria both as a function of PSE port and as a function of total static power load to Class N PD's?
• How much time does it take for the PSE to remove power given moderate PD overloads and how much time to restore power following bulk overload shutdowns?
• How does PSE power management respond to differing subsets of PSE portsexperiencing a variety of Class N PD connections?
• How stable is PSE power when operating at 95% of static power capacity over a prolonged period of time?

 

The 2nd generation Multi-Port Test Suite is simple to configure and requires just a single cycle sequence all test conditions to Type-1 (15.4W) and Type-2 (30W) PSE's.  New reporting is colorful with graphs and tabular summaries that convey critical PSE system behaviors.
