HPE 733660-B21 2U Small Form Factor Easy Install Rail Kit

733660-B21 is HPE's 2U Small Form Factor Easy Install rail kit. PartSurfer lists its spare as 744114-001, an easy-install rack-mount slide rail kit for 2U small form factor servers, and also shows 733661-B21, the 2U Easy Install SFF rail kit entry for Gen9.

HPE's DL380 Gen10 QuickSpecs list 733660-B21 as the 2U SFF Easy Install rail kit for that server and note that it does not include the cable management arm, which is sold separately as 733664-B21. The large form factor version for the same server is 733662-B21, so the choice depends on whether the server's drive cage is SFF or LFF rather than on the server model alone.

HPE states that its rail kits are designed for HPE racks that comply with the EIA-310-E standard, and that use in a third-party rack is at the customer's own risk. To confirm fit, check that the server is a 2U SFF model (for example a DL380 Gen10 8SFF or 24SFF chassis) and that the rack follows EIA-310-E, and add 733664-B21 if a cable management arm is needed.

For an LFF drive cage on the same server, the rail kit is 733662-B21; the cable management arm is sold separately as 733664-B21; see HPE Cables, Batteries, Adapters and Parts.
