New Server Cabling Three new Superdome cables designed for the sx2000 improve data rate and electrical performance: • an m-Link cable • two types (lengths) of e-Link cable • a clock cable m-Link Cable The m-Link cable (A9834-2002A) is the primary backplane to second cabinet backplane high speed interconnect. The m-Link cable connects XBCs between system and I/O backplanes. The cable uses 4x10 HMZD connectors with Amphenol Spectra-Strip 26AWG twin-ax cable material. The m-Link cable is designed with one length but it is used in several connecting points. Thus, you must manage excessive cable length carefully. The ideal routing keeps m-Link cables from blocking access of power and XBC modules. Twelve high-speed cables must be routed around the backplane frame with the support of mechanical retentions. The m-Link cable is designed with a more robust dielectric material than the legacy REO cable and can withstand a tighter bend radius. However, HP recommends keeping the minimum bend radius at 2 inches. e-Link Cable The e-Link cables (A9834-2000B) are seven feet long cables and the external e-Link cable (A9834-2001A) is 14 feet long. Both use 2-mm HM connectors with Gore 26AWG PTFE twin-ax cable material. The e-Link cable connects the cell to the local I/O chassis, and the external e-Link 42 Overview
