Shelf Management Module
Shelf Management Module
7.3.1 IPMB Connectivity
The IPMB is a dual radial topology. Each IPMC in the shelf connects to both SAM1620-Ds
for a redundant IPMB.
7.3.2 RS-232 Serial Interface
The SAM1620-D provides an RS-232 interface on the face plate connector using an RJ-45
connector. The connector is routed to the serial port of the shelf manager mezzanine.The
default baud rate is 9600, 8, N, 1.
Table 7-1
shows the pin assignments for RJ-45
connector.
The SAM1620-D provides an RS-232 interface on the alarm display panel at the front of
the chassis using a mini-D 9-pin connector. The connector is routed to the second serial
port of the shelf manager. The baud rate is 115200, 8, N, 1 and cannot be changed.
