The MAX 6000 unit’s back-panel indicator lights convey information about network traffic on
the unit’s Ethernet interface, packet collisions on the Ethernet network, full duplex operation
on the Ethernet network, 100BaseT (or 10BaseT) status, and the functional status of the
Ethernet interface. Figure 1-3 shows the MAX 6000 back-panel indicator lights, which display
the status of the Ethernet interface.

Table 1-3 describes the MAX 6000 unit’s Ethernet interface indicator lights.
B Fail
On only if one or more of the voltages from side B of the power supply
has failed (+12,+5, +3.3, -12, -5).
Fan
On when the fans are functioning properly (if +12 Vdc from either A or
B is good). This indicator light goes off in the event of a fan failure.
