Table 53 describes the ICM bus (loop) status LEDs.
The 4U, 60 DAE ICM input/output ports and connectors
The 4U, 60 DAE ICM supports the following I/O ports on the rear:
◆ Four 6-Gb/s PCI Gen 2 SAS ports
◆ One management (RJ-12) connector to the SPS
◆ One USB connector
6-Gb/s SAS x8 ports
The DAE ICM supports four (two input and two output) 6-Gb/s SAS x8 ports on the rear of
each ICM (A and B). This port provides an interface for SAS and NL-SAS drives in the DAE.
The port is a 26-circuit SAS small form-factor 8088 (SFF-8088) specification (socket or
receptacle) using an SFF-8088 specification mini-SAS 26-circuit cable (plug) with a pull
tab.
Note: Each SAS cable is keyed with an
in
and
out
connection to prevent incorrect cabling.
Figure 89 shows an example of the port connector (socket) and cable connector (plug)
with pull tab.
