The Dell UD458 is a CD-ROM drive designed for Dell PowerEdge 1850 1U rack servers. This internal optical drive connects via standard IDE interface and includes the factory tray and cable assembly required for installation. The UD458 reads standard CD-ROM media at typical speeds for legacy optical drives and mounts in the server's 5.25-inch bay. Compatible with PowerEdge 1850 configurations and similar 1U form-factor servers from that generation, this component is suitable for legacy system builds, OS installations, firmware updates, or environments where optical media support remains necessary. Refurbished units have been tested and are guaranteed to function; available via quote.
