Main system LEDs—Locator, Fault, and Power/OK—are repeated on the back panel.
(See
TABLE 2-1
,
TABLE 2-2
, and
TABLE 2-3
for descriptions of front panel LEDs.) In
addition, the back panel includes LEDs that display the status of each of the two
power supplies and both on-board Ethernet connections. Two LEDs located on each
Ethernet RJ-45 connector display the status of Ethernet activity. Each power supply
is monitored by four LEDs.
Details of the diagnostic use of LEDs are discussed separately in the section, “How
to Isolate Faults Using LEDs” on page 176.
