to the power or ground rails. Hence, the device prevents an unpowered ShMM-1500R from
loading down the HRI of the peer ShMM-1500R. It also prevents a carrier from detecting the
ACTIVE# output as a zero; that is, active, during a ShMM-1500R power cycle or a ShMM-1500R
power supply failure.
The FPGA device contains a built-in CRC error checker for detecting soft errors in the
configuration data. When a CRC error is detected the signal LATCH_CRC_ERROR is set active by
the ShMM-1500R CRC error detection circuit, which immediately sets the
ShMM_STATUS[0:1]_L and ACTIVE# signals high. The peer ShMM-1500R, if it is not already
active upon detecting the loss of the status serial bit streams, becomes the active ShMM-
1500R.
The HRI also includes 13 test points for in-service monitoring of the hardware redundancy
signals and for out-of-service diagnostics, enabling the ShMM-1500R to isolate failures on the
HRI to a single carrier +ShMM-1500R pair.
8.5.2.2 HRI Protocol
In the redundant configuration, the two ShMM-1500R boards communicate through the HRI
by exchanging data packets. The HRI continues to be operational in case of a single
interconnection failure and is able to detect a double failure. The HRI has a redundant
communication path, using four signals. In the case of a single wire permanent failure (the
signal gets stuck high, low or breaks), data packets continue to be transmitted through the
redundant communication path. A short between two of these four signals is considered a
double failure.
