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)
• I
2
C 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.
