Visual indicators
LEDs on ThinkSystem 4350 Series adapters provide a visual indication for the board hardware status. The
LED locations vary, and may be on the front of the board or back of the board (see Figure 1 “ThinkSystem
4350 Series LED locations” on page 4), and include DDR LEDs (also referred to as Flash-Based Write Cache,
or FBWC, LEDs) and status LEDs. The LED states are described in Table 2 “ThinkSystem 4350 Series Status
LEDs” on page 4.
Front panel brackets have three holes for the Heartbeat LED, Fault LED, and Crypto LED.
