HP

This collection holds HP parts. The J9775A is a switch from the 2530 Series with 48 ports of 1GbE RJ45 and 4 ports of 1GbE SFP. The JC680A is a 650W AC power supply and the JC682A is a fan tray, both for the 58x0AF. The 720211-B21 is a BladeSystem c-Class 40G QSFP+ to QSFP+ active optic cable, 15m long.

These parts are not interchangeable. The J9775A is a whole switch and comes with a rack-mount kit and power cables. The fan tray and power supply are hot-swappable and ship as the unit only, with no power cord or rack kit. The JC682A has back-to-front airflow, with intake on the power-supply side and exhaust on the port side. Check that this matches how your gear is racked. Also check that the fan tray and power supply match your 58x0AF model, and that your ports are 40G QSFP+ before you order the cable.
