NOTE:
There are two value sets for the upper temperature thresholds. One is set
for event notification and the other triggers higher fan rotation speed. The
preset value for event notification can be changed using the firmwareembedded configuration utility, while the fan speed trigger is not a user’s
option. Please refer to the Fibre to SATA RAID Subsystem Operation
Manual for the options with event notification values.

Figure 1-14: Host Connection Module
The hot-swappable host connection modules shown in Figure 1-14 are
secured to the enclosure chassis with two (2) hand screws. These parts come
with a mark on its faceplate to distinguish left-side or right-side module.
Each I/O module connects to one host channel and is configured with four
(4) 2Gbps FC ports that receive 2Gb speed SFP transceivers. SFP
transceivers are user-supplied items. You can order the field-replaceable,
SFP tranceivers (IFT-9270CSFP2GA01) from your subsystem vendor.
These SFP tranceivers have been selected and tested to provide the
necessary reliability and performance.
When the host connection module is installed with SFP transceivers, that
will allow you to connect the A24F-G2224 to host computer(s), and external
devices at transfer rates up to 2Gbit per second.
