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.
