Hot Swap Disk Drive Indicators
Each of the Hot Swap hard disk drives has two LED indicators, one for
operational status and one for activity status. Light pipes on each drive module
transmit light to the front from the LEDs on the inside rear of the hot-swap mass
storage cage. See Table 2-3 and Figure 2-3.
