Description

The HDMP-0480 is an Octal Cell Port Bypass Circuit (PBC). This device minimizes part count, cost and jitter accumulation. Port Bypass Circuits are used in hard disk arrays constructed in Fibre Channel Arbitrated Loop (FC-AL) configurations. By using Port Bypass Circuits, hard disks may be pulled out or swapped while other disks in the array are available to the system.
