IBM feature #1901 is the additional power supply (4U) for the IBM TS3200 Tape Library, machine type 3573, IBM part number 23R7263. The 2U library has one power supply, while the 4U library has a minimum of one and takes a redundant power supply. Feature #1901 is the 4U option only.
The library needs a 110/220 volt AC connection, 100-127 VAC or 200-240 VAC at 50-60 Hz. A 4U library needs two separate power sources to implement redundant power, one for each supply. The 4U library has power supplies with LEDs: blue means AC voltage is available, amber means a possible fan problem or another power supply fault, and green means DC power is OK and active.
In a library manufactured after March 14, 2008 that uses redundant power, the System status screen displays the power supply status, and a failed redundant supply raises a warning event with a flashing Attention LED. With -04 level redundant supplies the supply in standby mode normally has its green LED off, and with -05 level supplies both green LEDs are on. Three blue captive thumbscrews hold each supply to the rear panel.
