Lenovo 4X97A86421 SR655 V3 3.5IN R SAS CA KIT

Lenovo 4X97A86421 SR655 V3 3.5-Inch Rear SAS Cable Kit

Overview

The 4X97A86421 is a factory-new Lenovo rear SAS cable kit designed for 3.5-inch drive bay configurations in the ThinkSystem SR655 V3 server. When expanding or replacing storage wiring in an SR655 V3 chassis, using the correct OEM cable assembly eliminates connector mismatch and signal integrity issues that generic aftermarket cables can introduce on SAS backplane runs. This kit targets integrators performing storage bay builds or field replacements where the rear drive cage must be wired to the system's SAS controller or expander.

Compatibility

Designed for the Lenovo ThinkSystem SR655 V3 platform. The 3.5-inch rear designation means this kit fits rear-bay drive cage assemblies — not front 2.5-inch SFF configurations. Confirm your SR655 V3 chassis order includes the rear 3.5-inch drive cage option before sourcing this cable kit; front-bay and 2.5-inch configurations require separate cable assemblies. Consult the SR655 V3 server accessory compatibility matrix or the Lenovo ThinkSystem catalog to cross-reference cable kits against your specific backplane and controller pairing.

Installation Notes

Route the SAS cables per the SR655 V3 maintenance manual to avoid pinch points near the rear fan wall. SAS signal cables are polarity- and keying-specific — do not force connectors. The kit ships at 10 lb, which reflects packaged weight; actual cable assembly weight is nominal. Country of origin is Mexico. UNSPSC code 43211600 (Computer Equipment) applies for procurement classification. No additional power tools required for cable installation; standard server-deployment hand tools suffice.
