2.1.6 Power Supply Module (PSM)
Two types of power supply modules are available:
• PSM-AC: 100 – 240 VAC (power rating 300 W);
• PSM-DC: 48 V DC; 9 A maximum (power rating 300 W).
Note the following:
• Each IHU can support two PSMs, where the second PSM provides redundancy in case one of the supplies fails.
• In cases that a single power supply module is installed, it must be installed in the LEFT slot.
• Both types of PSM modules (AC and DC) can be installed in the same chassis (at the same time).
• If two PSM modules are installed, both must be connected to their respective power source and turned on at all times.
PSM-AC
The PSM-AC includes an AC power connector, on/off switch
and power status LED.
