3.1.1.4 Power Supply Status Indicators
The IS50XX 36 Port Switch is available with one or two factory installed Power Supply Units. For
switches with only one unit installed, a second Power Supply Unit can be added to increase secu-
rity, hot-swap ability and to add redundancy. See Section E, “Replacement Parts Ordering Num-
bers,” on page 71 for ordering part numbers.

The primary power supply unit (PSU1) is located on the right side of the power side panel, with
