Expansion Hub Unit Status and DL/UL Status LED States (continued)
Table 4-1
LED State Indicates
Green / Green • Optical power received is above minimum (the Main Hub is con-
nected) although the cable optical loss may be greater than recom-
Green / Green
mended maximum.
(60-ppm)
• Optical power transmitted (uplink laser) is normal and communica-
tions with the Main Hub are normal.
• The Expansion Hub is reporting a commanded lockout.
Green / Red • A fault condition was detected, optical power received is below mini-
mum.
Red / Green
(the Main Hub is not connected, is not powered, or the Main Hub's
downlink laser has failed, or the downlink fiber is disconnected or
damaged.)
Green / Green • The Expansion Hub is reporting a fault condition.
• Optical power received is above minimum (Main Hub is connected)
Red / Red
although the cable optical loss may be greater than recommended
maximum.
• Optical power transmitted is below minimum (Expansion Hub uplink
laser has failed; unable to communicate with Main Hub).
LED state must be checked within the first 90 seconds after power on.
If initially green, then red after 90 seconds, it means that there is no
communication with the Main Hub. If red on power up, replace the
Expansion Hub.
Green / Red • Optical power received is below minimum (the Main Hub is not con-
nected, is not powered, or the Main Hub's downlink laser has failed,
Red / Red
or the downlink fiber is disconnected or damaged.)
• Optical power transmitted is below minimum (the Expansion Hub
uplink laser has failed; is unable to communicate with the Main Hub).
UL STATUS
after power on. If initially green, then red after 90 seconds, it means
that there is no communication with the Main Hub. If red on power
up, the uplink laser has failed, replace the Expansion Hub.
Green /Off • Expansion Hub is in factory test mode, return it to the factory.
Green / Off
Red/ Don't • One or more power supplies are out of specification. The hub needs to
Care be replaced.
Red/ Don't
Care
Green/ Red • Expansion Hub failure. The Hub must be replaced.
Off/ Off
RJ-45 Port LEDs
The Expansion Hub has a port LED, labeled
Type F ports. The port LEDs can be in one of the states shown in Table 4-2. These
LEDs can be:
