How to install CRU RAX420-XJ DAS Hard Drive Array

Installing the CRU RAX420-XJ is designed to be straightforward, with an emphasis on quick, tool-free drive integration and simple rack mounting. Begin by identifying a suitable 19-inch rack location with adequate airflow and accessible cabling. Ensure your host system has a compatible controller or adapter that supports a Multilane SFF-8088 interface and can recognize the DAS JBOD as a separate storage resource. If you are replacing or expanding existing storage, plan the drive order and cabling to minimize disruption to active workloads.

Step‑by‑step guidance:

• Power down the host system and verify that the rack space is clean, free of debris, and properly grounded.
• Mount the CRU RAX420-XJ into the 2U rack enclosure, aligning with rack rails, and secure it to ensure stability during operation.
• Insert up to four 3.5" SATA hard drives into the TrayFree bays. The bays are designed for tool-less installation—no screws or trays required. Gently slide each drive into its bay until it seats firmly.
• Connect the external Multilane SFF-8088 cable from the CRU RAX420-XJ to a compatible host adapter or RAID controller on your server or workstation. Ensure cables are routed neatly to avoid interference with airflow and other components.
• Power on the enclosure and the host system. If required, initialize and format the drives through your operating system or storage management software, and configure the DAS as JBOD or as part of a larger storage pool according to your workflow needs.

Post‑installation, monitor drive health and performance using the system’s storage management tools. The TrayFree design supports rapid future upgrades; simply repeat the drive insertion process when capacity grows. For best results, maintain proper cooling and airflow around the enclosure to sustain consistent performance and prolong drive life. This CRU DAS array is built to be a practical, scalable addition to a wide range of environments, from creative studios to enterprise backup infrastructures, delivering dependable expansion without sacrificing rack space or ease of maintenance.
