Status LEDs (LED View)
The Status LEDs window (LED View) contains a Word/Byte LED and a Frame/Packet LED for
each port. If not all port LEDs are visible, increase the size of the window or use the scroll bar.
Words are the typical size of a unit of traffic in Fibre Channel, which are 32 bits that are encoded
to 40 bits on the wire. In SAS/SATA, the same quantity is referred to as a Dword. In Gigabit
Ethernet, the unit of traffic is a byte. All Ordered Set, Frames, Primitives, and Packets are made up
of words or bytes. Frames/Packets are structures that begin with SOF and end with a CRC and
EOF. The meaning of the LEDs for words and frames are shown below. These definitions apply to
the LED View, the LED Summary View, and the Resource Browser.
Right-click the view to access the
Preferences
dialog box.
Unselected error types (as configured within the
Frame Errors
tab, the
Phy Errors
tab, and the
SAS/SATA Errors
tab of the
Preferences
dialog box) are not used in determining the value of a
status LED for a port. For example, if CRC errors are not selected, and the only errors discovered
for a port are CRC errors, the status light for that port will remain green.
The LED will stay red if the error condition persists. If the error condition stops, the LED will turn
to yellow instead of green. An example is shown in Figure 76.
To reset all LEDs from yellow back to all green, select
Reset LEDs and Counters
from the
Edit
menu.
Table 9: Word and Frame Status LEDs
Word/Byte LED
Reason
Black
No signal or no light, often a result of a disconnected cable or
unplugged SFP module
Red
Signal with errors, for example, illegal characters, running
disparity violations, CRC mis-matches
Yellow
Had an error in the past, currently no errors
Green
Good signal, legal characters, proper disparity, good CRC if
present
Frame/Packet LED
Reason
Black
No Frames detected
Red
CRC mismatch error detected
Yellow
Had a CRC error in the past, currently no errors
Green
Frames with good CRCs detected
