LED Colors and Their Meanings

HF1 Switch LEDs
The HF1 switch LED colors and meanings are explained below.
❏ For each port on the switch:
✓ If the port is not operational, the LED is off. Some of the possible
reasons for this happening are the following:
— A cable is not attached correctly to the port or no cable is
attached at all.
— The switch port is connected to a non-operational adapter in
an HP 9000. (See “Adapter LEDs” on page 159 or Table 6-2
on page 161 for some tips about a non-operational adapter.)
— The cable is bad.
— The switch port is bad. Note that if a switch port is bad, and
(for some reason) you cannot use a different port on the
switch, you must replace the entire switch. However, you
first should try turning the switch’s power off and then back
on.
✓ If the connection from the port to the corresponding adapter in
the HP 9000 is operational, the LED on the port shows as solid
green.
✓ If data is flowing between the port and the corresponding
adapter, the LED shows as flashing green. Note that data does
not start to flow until HyperFabric initialization has occurred
(see “Using the clic_init Command” on page 95).
Note that each port and its LED are labeled with the port number
(“0” through “15”), but not with the name of the LED (unlike the
adapter’s LEDs, which might have an individual, specific label for
each LED [for example, “Connected/Traffic”]). However, a legend
listing the possible port states—disconnected, connected, and traffic
flowing—and the corresponding LED colors is printed on a label on
the back of the switch, for your reference. See Figure 3-2 on page 66
for the location of the label.
❏ For the “Power” LED on the switch:
✓ If the power to the switch is off, the LED is off.
✓ If the power to the switch is on, the LED shows as solid green.
