Table 2.2 Routers 1–5 Status LED Legend
Color Description
Off No power to MPR-50.
Green on steadily
Router is configured. No errors have been detected on the
router or on the external channel to which it attaches within
the past 10 seconds. The channel has been idle for at least
the past 10 seconds.
Green slow flashing
Router is configured. No errors have been detected on the
router or on the external channel to which it attaches within
the past 10 seconds. There has been traffic on the channel
within the previous 10 seconds.
Slow flashing is defined as on-for-one-second/off-for-one-
second.
Yellow on steadily
If the Monitor LED is also yellow on, the router Status LED
does not indicate the router state—the router will still be
routing if it was previously configured to do so. If the
Monitor LED is not yellow on, then the router is disabled or
offline, and is not routing messages.
Yellow slow flashing
Router unconfigured or not responding.
Slow flashing is defined as on-for-one-second/off-for-one-
second.
Orange fast flashing
An alarm condition on the router or its attached external
channel has been detected within the past 10 seconds.
After the alarm condition clears, the router Status LED will
revert to another status. The alarm condition will continue to
be reported by the Monitor Status LED for as long as power
is continuously applied to the router, even after the condition
is cleared.
Fast flashing is defined as on-for-one-half-second/off-for-
one-half-second.
