2502tr, 2511, 2514 (top)
There are no lights on the front of these routers. The System OK will be on when the router has power. The Ethernet and Serial lights will blink when activity is present.

LED	Desrcription
Power	On when power is supplied to router
RPS	Off•no rps1 is attaced On•RPS is attached and operational Blink•RPS is attached, but has a failure
Activity	OFF—In the Cisco IOS software, but no network activity. Blink (500 ms ON, 500 ms OFF)—In ROMMON, no errors. Blink (500 ms ON, 500 ms OFF, 2 sec between codes)—In ROMMON, error detected. Blink (less than 500 ms)—In the Cisco IOS software, the blink rate reflects the level of activity.

LED	Desrcription
LINK	When on, a link has been established with the hub or switch at the other end of the cable.
FDX	When on, the interface is in full-duplex mode. When off, the interface is in half-duplex mode.
Mbps	When on, the speed of the interface is 100 Mbps. When off, the speed of the interface is 10 Mbps.

36xx (top)
The 36xx series routers that MOREnet provides are not V.92 compatible (some of these routers have modems on them). There are no lights on the front of these routers. A csu/dsu may be built in to this unit. It may also have a modem pool hanging off it. There are no light patterns that we need to report on this router. Just make sure that the customer can see any green status light, and that it is lit on the back of the router (indicating that it is getting power).

7204, 7507 (top)
There are no lights on the front of these routers. A csu/dsu is already built in to this unit. There are no light patterns that we need to report on these routers. Just make sure that the customer can see any green status light, and that it is lit on the back of the router (indicating that it is getting power).

Bat 56 (top)
When properly operating all 6 lights should be lit. No test mode lights should be lit.

If test mode lights are lit, try pressing the Select button until all of the test mode lights go out.

INS	When on steady indicates correct ( In Service) pattern from the TELCO Flashes when there is no receive line, when out of service pattern is sent by TELCO or unit is out of frame, or when in self test or Line Loop Mode
CD	When on indicates actual valid data being received When off either not In Service or Idle Signal is Received
RTS	When on indicates RTS present from the terminal When off indicates no RTS
CTS	When on indicates that you are in service and have a valid RTS When off indicates one of the above conditions does not exist.
TXD	Flashes when transmit data is present.
RXD	Flashes when receive data is present.
Test Mode Lights:
ST	Self Test - Flashes red while awaiting confirmation of correct self test. Flashes green when unit passes self test
DL	Digital Loop - When flashing indicates bi-directional digital loop selected. When on steady indicates telco central office has commanded DSU loop
LL	Local Loop - When flashing Line Loop has been selected. When on steady indicates telco has commanded a CSU loop.
RT	Remote Test - When on steady green indicates other end other end sending remote test. Flashes red while local end local end is awaiting valid response from remote end, flashes green when valid response is received.
Select	Push button switch that selects test mode.

Bat T1 (top)
When properly operating the INS, TXD, and RXD are lit. The TXD and RXD lights may flicker slightly. No test mode lights should be lit. If any test mode lights are lit, try pressing the Select button until all of the test mode lights go out.

INS	When on steady Green indicates unit in service.
ERR	When on indicates line errors being received or invalid line.
TXD	Flashes when transmit data is present.
RXD	Flashes when receive data is present.
Test Mode Lights:
ST	Self Test - Flashes red while awaiting confirmation of correct self test. Flashes green when unit passes self test. This test will not initiate unless the line is disconnected
DL	Digital Loop - When flashing indicates bi-directional digital loop selected.
LL	Local Loop - When flashing Line Loop has been selected. This test will not initiate unless the line is disconnected
RT	Remote Test - When on steady green indicates other end other end sending remote test. Flashes red while local end local end is awaiting valid response from remote end, flashes green when valid response is received. This test requires requires like configured BAT ELECTRONICS units at both ends.
Select	Push button switch that selects test mode. Select button also is used to confirm configuration selections.

Motorola FT 100s (top)
CS should be on and RD and TD flickering fast enough to appear solid. If any of these lights are on (los, tm, alm) there is a problem. See here for more details than you can shake a stick at.

LED	Color	Description
TD	na	Transmit data indicates activity on the DTE transmit data line. Flashing indicates data is being transmitted. Solid ON indicates a low state on the transmit data line, and a solid OFF indicates a high state or no data being received.
RD	na	Receive data indicates activity on the DTE receive data line. Flashing indicates data is being received. Solid ON indicates a low state on the receive data line, and a solid OFF indicates a high state or no data being transmitted.
CS	na	Clear to send indicates the status of the DTE clear to send signal.
LOS	Yellow	Loss of sync indicates that the unit has either lost the network T1 frame sync or the signal.
ALM	Yellow	Alarm indicates an alarm condition exists on the T1 network interface.
TM	Yellow	Test mode indicates that the unit is in a network or DTE mode.

Kentrox Satellite 651(top)
Under normal working conditions the T1 light is not lit. When the T1 light comes on there is most likely a telco problem. Rxd, TxD, CTS, and RTS are all on under normal conditions. The T1 light will be red, and the other lights will either be yellow, or off. The power light is green, or red depending on the circumstance. Find the PDF here.

LED	Color	Description
PWR/FAIL	Green/Red	Green Power is on, self-test successful. Green, blinking A user is logged into the Satellite 651 via ARC. Blinking red A test is active. Red Power is on, self-test failed. Off No power is being received.
T1	Red	One or more of the following has occurred on the network interface (see LCD status display): ‹ LOS alarm. The T1 signal has been lost. ‹ OOF alarm. The T1 signal is out-of-frame. Some or all of the DS1 framing bits have been lost. ‹ Incoming AIS alarm. The far-end equipment (NAIS) is in test or alarm state. ‹ Yellow alarm. The far-end equipment (NYEL) is experiencing LOS or OOF.
TxD	Yellow	Yellow Data is being transmitted (input) at the data port. Note that under normal conditions this LED may fluctuate in intensity. Extended ³off² Zeroes are being received at the data port. Zeroes are transmitted to the network if RTS and CTS are high.
RxD	Yellow	Yellow Data is being received (output) at the data port. Note that under normal conditions this LED may fluctuate in intensity. Off Zeroes are being output at the data port if RTS and CTS are on.
CTS	Yellow	Yellow Channels are assigned, and NI is not in alarm. The Satellite 651 is ready to exchange data with the DTE. Off This LED is off when it is not possible to transmit data out the data port. This may be because an NI alarm is present or the data port is not programmed or no channel is assigned.
RTS	Yellow	Yellow Request to send is asserted. The DTE is ready to send data to the Satellite 651, according to the conditions established by the DPLOS command. Off The DTE is not ready to send data (per the conditions configured by the DPLOS command) or is not connected or channels are not assigned.

Adtran TSU Ace(top)
The lights on this csu are PWR, ERR, ALM, TEST, TD, RD, CS, and RS. The lights that should normally be on are: TD, RD, CS, RS, and PWR. If the ALM, or ERR lights remain on after a power cycle, route the ticket!
