You seem to be correct about the first one.. sorry about that.
However, the second one supports Link Aggregation:
* Jumbo Packet support: to improve performance of large data transfers
Resiliency and high availability
* IEEE 802.3ad Link Aggregation Control Protocol (LACP): provides link-level redundancy with support for up to 4 trunks on the ProCurve Switch 1800-8G and 12 trunks on the ProCurve Switch 1800-24G, each with up to 8 links (ports) per trunk
