7.1.2 Diagnostic LEDs
The diagnostic LEDs report the following information about the current status of the AP, as
described in Table 11.
NOTE: Table 11 identifies the LEDs in order of their left-to-right position as the cable
connections face downward.

LNK/5 green Ethernet link Continuously lit when link is present.
ACT/4 orange
Presence of data activity

Flashes during data transfer. Frequency of flash is
not a diagnostic indication.
GPS/3 red Pulse of sync Continuously lit as pulse as AP receives pulse.
SES/2 green
Unused on the AP
SES is the session indicator on the CMM.
SYN/1 orange Presence of sync Always lit on the AP.
PWR red DC power Always lit when power is correctly supplied.
7.2 CABLING THE AP
The use of shielded cable for all Canopy infrastructure associated with Backhaul, Access Point,
and CMMs is strongly recommended. The environment these modules operate in often has
significant unknown or varying RF energy. Operator experience consistently indicates that the
additional cost of shielded cabling is more than compensated by predictable operation and reduced
costs for troubleshooting and support.
7.2.1 Standards for Wiring
The following information describes the wiring standards for installing a Canopy system.
All diagrams use the EIA/TIA-568B color standard.
Either RJ-45 straight-thru or RJ-45 crossover cable can be used to connect a (network interface
card), hub, router, or switch to a module. Canopy modules that are currently available can auto-
sense whether the Ethernet cable in a connection is wired as straight-thru or crossover. Some
modules that were sold earlier do not.
