Expansion module
The 5U84 expansion enclosure uses the same IOMs that are used by 2U12 and 2U24 enclosures.
Power supply module
This figure shows the power supply unit that is used in 5U controller enclosures and optional 5U84 expansion enclosures.

LED behavior:
● If any of the PSU LEDs are illuminated amber, a module fault condition or failure has occurred.
● For a detailed description of PSU LEDs, see FCM LED states on page 36.
The 5U84 enclosures use separate CRU modules for power supply and cooling/circulation, respectively. Power supply unit
(PSU) on page 19 shows the power supply module, which provides the enclosure with power connection and a power switch.
Fan cooling module (FCM) on page 19 shows the fan cooling module that is used in 5U84 enclosures. The FCM is smaller than
the PCM, and five of them are used within the 5U enclosure to provide sufficient airflow throughout the enclosure.
Fan cooling module
The following figure shows the fan cooling module (FCM) used in 5U controller enclosures and optional 5U expansion
enclosures.

LED behavior:
● If any of the FCM LEDs are illuminated amber, a module fault condition or failure has occurred..
