Indicators on the IBM 2210
The IBM 2210 has green and amber light-emitting diodes (LEDs) that indicate the
status of the system and of individual ports.
Green indicates normal operation.
Amber indicates the presence of a problem.
The indicators appear on the side of the IBM 2210 containing the ports and are
duplicated on the side that is opposite the ports. This arrangement allows the cus-
tomer to use either side as the “front.”
Figure 1-12 shows the indicators that appear on the side of the IBM 2210 con-
taining the ports. Note that this illustration shows Model 12T; the port LEDs on
different models are tailored to the particular ports supported.
