Pros: I have now purchased 15 of these for our company to replace the DLink DGS1224T (rev c) which I do not recommend under any circumstances. These work very well. No fans, silent. Web management. Lifetime warranty. Direct 800 number to Procurve support.

Cons: Supplied parts kit included 4 bracket screws instead of the required 8 (4 per bracket). This was true for all 15 units purchased in three separate orders. HP Procurve support sent replacement kits overnight. The correct part number for the kit is 5069-6535. User manual is incorrect. These switches cannot send SNMP traps to a trap receiver and do not support Spanning Tree Protocols (STP) if these are features that you require.

Overall Review: Recommended.

Overall Review: Has a smaller battery compartment so will not take the more common 12v 7ah or 12v 9ah battery sizes. The 650 VA unit is able to do that which is a plus.
