10 Intel NetStructure® MPRTM0020 Technical Product Specification – April 2006
Functional Overview
•One SAS x4 connector to support external SAS JBOD. (Only three of these SAS ports on the
RTM are usable; the first SAS port is used by the MPCBL0020 Single Board Computer’s local
SAS drive.)
•Six T1/E1 ports with transformer and protection circuitry (designed primarily for intra-
building applications)
•I2C connectivity to the SBC for remote management capabilities
•OOS and Health LEDs
•Hot Swap status LED. This LED mirrors the indication of the HS status LED on the
MPCBL0020 Single Board Computer since the MPRTM0020 RTM itself is not hot swappable.
•P30 power connector
•P31, P32, and P33 HM- ZD connectors for SBC signals
•On-board power conversion from +12V supplied by the SBC via P30 connector
•ADM1026 for voltage monitoring, storing FRU and SDR data.
