NOTE:
The preceding figures show dual-IOM configuration. Alternatively, you can configure the 2U controller enclosure with a
single-IOM. In single-controller configurations, the controller module installs into IOM slot A, and an IOM-blank is fitted to IOM
slot B.
2U rear panel components
This section describes the controller module and expansion module components.
Controller module
The top slot for holding IOMs is designated A and the bottom slot is designated B. The face plate details of the IOMs show the modules
aligned for use in A. In this orientation, the IOM latch appears at the bottom of the module. It is shown in closed/locked position. The
diagrams below identify ports.
See
Figure 31. LEDs: ME4 Series Storage System FC/iSCSI controller modules (FC and 10GbE SFPs)
for LED identification. These
diagrams also show proper orientation for IOM insertion into slots located on the 5U84 enclosure rear panel. CNC host interface ports that
can be configured with 16Gb/s FC SFPs or 10 GbE iSCSI SFPs.
