2. System Maintenance
This section explains some common maintenance procedures.
2.1 Replace an Interface Module (Hot Swap)
Interface Modules can be removed and replaced without shutting the system down.
Interface Modules must be replaced with the same type of card.
To perform a “hot swap” of an Interface Module:
1. From the Operator’s Console, select F2, Port Card Status. Display the port card
to be swapped, so you can monitor its status during the process.
2. On the card to be replaced, move the Normal/Disable switch to the Disable
position. This locks the card and disables the Base Stations to prevent new calls
from starting, but does not drop active calls. Existing calls are allowed to
complete before the card is locked.
3. When the alarm light stops blinking and turns solid red, the card is idle. Verify
this on the Operator’s Console, all lines and Base Stations should show no
activity. If you unplug the card before it is idle, the system may alarm.
4. At the Operator’s Console, press ESC. This stops the Operator’s Console from
trying to monitor the card you are about to remove.
5. Unplug the 25 pair cable from the card.
6. Unscrew the card from the shelf and slide it out.
7. Slide the replacement Interface Module into the slot, until the card clicks into
place. Tighten the screws at the top and bottom of the card to secure it.
8. Connect the 25 pair cable to the card.
9. When the heartbeat LED sequence displays on the Interface Module (LED 1
flashes 1/3 of the time), select
the new card. It should be
F2 on the Operator’s Console to verify the status of
Running.

3. Wireless Telephone Problems
3.1 Using the Link Wireless Telephones
The Link WTS is an in-building wireless communication system that allows hand-held
Wireless Telephones to communicate using the existing telephone system. Calls are sent
to and received by the Wireless Telephones via small radio transceivers called Base
Stations, located throughout the building or campus. When using and troubleshooting the
Wireless Telephones, consider the following concepts.
Call hand off – as the user moves through the facility, your conversation will be
“handed off” from one Base Station to another.
In range/Out of range – service will be disrupted if a user moves outside the
transmission area of the Link WTS. Service is restored if the user moves back within
range of a Base Station. If a call drops because a user moves out of range, the
Wireless Telephone will recover the call if the user moves back into range within a
few seconds.
Capacity – in areas of heavy use, the call capacity of a particular Base Station may
be filled. If this happens, the user can wait until another user terminates a call, or
move within range of another Base Station and try the call again. If a user is on a call
and moves into an area where capacity is full, it is the same as moving out of range of
a Base Station.
Transmission Obstructions – a thorough site survey was done prior to installation
to determine the best location for Base Stations for optimum transmission coverage.
However, small pockets of obstruction may still be present, or obstructions may be
introduced into the facility after system installation. This loss of service can be
restored by moving out of the obstructed area. Base Stations can also be added to
overcome obstructions.
3.2 No Extension/Wrong Extension Displayed
1. Hold down the FCN key until Volume Level display.
2. Press the # key twice until the display reads “Extension.”
3. Press
4. Press END when finished.
0, then enter the correct extension number.
Part Number: 72-0059-04-E.doc Page 17
SpectraLink Corporation Maintenance and Diagnostics
Link WTS – Link 3000 MCU
3.3 “No Svc” Displayed
The Wireless Telephone is either not registered, out of range, or can’t pick up a signal
from a Base Station.
1. Visually check to see if the telephone is within range of a Base Station where
other telephones are working.
2. From the Operator’s Console, search for the telephone’s serial number or
extension number to be sure it is properly registered.
3. If other telephones in the area are also not working, see Multiple Wireless
Telephones Not Working below.
3.4 No Dialtone / No Audio
If the Wireless Telephone has no dialtone, or if the user is unable to hear the other party’s
voice or heard echo or dead air.
1. Be sure the Wireless Telephone is powered on.
2. Be sure the No Svc icon turns off a few seconds after the Wireless Telephone is
powered on.
3. Swap the Battery Pack with a Battery Packfrom a functional Wireless Telephone.
If this corrects the problem, charge the Battery Pack.
4. Turn the Wireless Telephone off then on again, then test again for dial tone and
voice quality.
5. Move through several Base Station areas to be sure the Wireless Telephone is
within range of an operating Base Station.
6. Check for alarms on the System Controller, Shelf Controller, or Interface Module
cards (F1, Supervisor State or F2, Port Card State). If the Wireless Telephone
is connected through a digital interface, the system will show an alarm. If the state
is anything but idle, the Wireless Telephone is in alarm. If there are alarms, see
Troubleshooting Alarms section.
7. Check that the system connects when the user goes off-hook. On the Operator’s
Console, from theF2 -
Port Card State screen, view the status of the Line when
the user goes off-hook.
8. Make sure the Wireless Telephone’s Interface Module is connected to a working
phone line. Use a telephone test set to check the line at the demarc block.
9. Check the cabling between the Interface Modules and the demarc block, and
between the demarc block and the telephone system ports. See Link WTS – Link
3000 MCU: Installation for more information.
10. Isolate the Wireless Telephone line on the PBX from the Link 3000 MCU.
Connect a wired telephone to the port to see if the wired telephone operates
properly.
11. Move the Wireless Telephone to a different port location and test again.
Part Number: 72-0059-04-E.doc Page 18
SpectraLink Corporation Maintenance and Diagnostics
Link WTS – Link 3000 MCU
3.5 No Handoff
If the user walks between Base Station coverage areas, the conversation is not handed off,
and the call is dropped.
1. Using another Wireless Telephone, confirm that both Base Stations are
operational.
2. Verify that the Wireless Telephone can hand off between other Base Stations.
3. On the Operator’s Console, from the Port Card State screen (F2) check the status
of the Base Stations. It is possible that the Base Stations have four calls (the
maximum) in progress. If the Base Station is handling three or fewer calls and
still drops the call, see Base Station Problems.
3.6 Calls Ring on the Wrong Wireless Telephone
The Wireless Telephone has probably not been registered correctly.
1. From the Operator’s Console, use the Search function to find the telephone’s
serial number and check its port location.
2. Trace the wires from the back of the Interface Module to the host telephone
system to be sure it is actually connected to that port location.
3. If the physical location is different, note the correct port location. From F4 - Port
Card Configuration Display and Administration
, use the Edit Line function to
change the serial number on the correct port. If the port location is already in use
by another Wireless Telephone, you will need to delete the other telephone (using
Delete Line), then change the serial number on that port location to the serial
number of the new telephone.
3.7 Multiple Wireless Telephones Not Working
If several of the Wireless Telephones are not working there may be a problem with the
Interface Module that controls them, or with one or more Base Stations.
1. Check to see that the Wireless Telephones are correctly registered. See Link WTS
– Link 3000 MCU: Operator’s Console for instructions.
2. At the Operator’s Console, use the
Wireless Telephones (searching for serial number, extension, or user name). If
they are all connected to the same Interface Module, there may be a problem with
that Interface Module.
3. Try replacing the Interface Module with a different Module of the same type (see
Replacing Interface Modules.)
Search function to display details about the
4. Check the cabling between the Interface Modules and the demarc block, and
between the demarc block and the telephone system ports. See Link WTS – Link
3000 MCU: Installation for more information.
5. If the problem persists, diagnose the Base Stations.

4. Base Station Problems
The first step in diagnosing Base Station problems is to isolate the problem to the Base
Station. Be sure the problem is not limited to a single Wireless Telephone. When a
problem occurs with a Wireless Telephone, try the same procedure using another
telephone, or several telephones (see Wireless Telephone Problems.)
If all or several Wireless Telephones are affected, try the following troubleshooting
procedures.
If you try the following troubleshooting procedures and the Base Station still does not
work, return the unit to SpectraLink for service.
4.1 Multiple Base Stations Not Working
If several of the Base Stations are not working there may be a problem with the Interface
Module that controls them.
1. At the Operator’s Console, check for alarms on the Supervisor State (F1) and
Port Card State (F2) screens. Cards or components in alarm will have an
exclamation point (!). See Troubleshooting Alarms for more information.
2. Check to see that the Base Stations are correctly registered. See Link WTS – Link
3000 MCU: Operator’s Console for instructions.
3. If all of the Base Stations are connected to the same Interface Module, there may
be a problem with that Interface Module. Try replacing the Interface Module (see
Replacing Interface Modules) and re-testing the Base Stations.
4. Use a voltmeter to check for 48V DC on the Base Station wiring.
4.2 Base Station LED not lit
The Base Station is not receiving power. On the Port Card Status screen (F2) the status
may show Reset.
1. Be sure the RJ-45 connector is plugged into the Base Station.
2. Be sure the MCU is turned on.
3. With a voltmeter, check the 48V DC on the wiring between the MCU and the
Base Station.
Part Number: 72-0059-04-E.doc Page 20
SpectraLink Corporation Maintenance and Diagnostics
Link WTS – Link 3000 MCU
4.3 Base Station LED Flashing Red and Green
The LED on the Base Station is designed to flash in specific colors and patterns to reflect
its functioning. At startup the system goes through a “listen” procedure to ensure that the
Base Stations do not interfere with each other. During the “listen” process the LED will
flash red and green for approximately two minutes.
Certain flashing patterns indicate a problem that needs to be addressed:
If the System Controller disables a Base Station because it interferes with another
Base Station, the disabled Base Station’s LED will flash red and green.
If the Base Station is stuck in “download” the LED will flash red and green. In this
case, verify the status of the Base Station at the Operator’s Console. Select F2 -
Interface Module Status.
If status is Disabled, see Base Station Disabled, below.
If status is Download and the DL Time is longer than 1-2 minutes, see Base Station
Will Not Download, below. Also:
Try disconnecting and reconnecting the power from the Base Station. Unplug
the RJ-45 connector on the Base Station then plug it back in again, or remove
the bridging clips from the demarc block and replace them. If necessary, reset
several Base Stations at once by removing the cable from the Interface
Module. Remember, this will also disconnect Lines and drop calls!
Make sure there are no bridge taps (Ys) on the demarc blocks. Remove any
you find.
Use a voltmeter to check the lines for the 48 V dc to be sure there are no
power problems.
4.4 Base Station Disabled
The System Controller will disable a Base Station if it is too close to another Base Station
or if there are communication errors between the Base Station and the System Controller.
Once disabled the Base Station does not handle any calls.
1. On the Port Card Display (F2) check that the status of this Base Station is
Disabled.
2. Before moving Base Stations, check the facility’s floorplan and the latest Listen
Verify diagnostic (F1,
errors and information.
3. To enable this Base Station, disconnect it and relocate it so it is farther from other
Base Stations.
4. Disconnecting and reconnecting the Base Station will automatically activate the
“listen” procedure. Run the Listen Verify Diagnostic (F1, Run Listen Verify) and
review results to be sure the problem is corrected without creating any new
problems.
Check Listen Verify Report or Show Listen Report) for

Link WTS – Link 3000 MCU
4.5 Base Station Will Not Download
If a Base Station is stuck in download, the LED may flash red and green or just red; the
status on the Operator’s Console will show Reset or Download; and the Base Station
will be locked up (not handling calls).
1. At the Operator’s Console, check to see that the Base Station is registered, using
F2 - Port Card Display.
2. Check the status of the Base Station. If the status shows Download or Download
Data, the Base Station has locked up during download.
3. To reset the Base Station: From F2, Port Card Display, highlight the Base
Station and press Enter, then select Reset RCU from the menu.
4. If the Base Station still does not download, try disconnecting power from the Base
Station and then reconnecting it (unplug the RJ-45 connector on the Base Station
then plug it back in again, or remove the bridging clips from the demarc block and
then replace them.)
5. On the Port Card Display (F2) screen, select the Base Station in question and
press Enter to show Base Station Detail. This shows continuous update of the
Base Station’s status. The DL Errors field shows the number of Download Errors.
Any number greater than 0 indicates a problem. RCU Link shows current
transmission errors. These errors are generally caused by hardware problems.
Contact SpectraLink Customer Support for assistance.
4.6 Base Station LED Flashing Red
This indicates that the Base Station is not communicating with the MCU.
1. Follow the instructions in Base Station LED Flashing Red and Green.
2. Be sure there are no bridge taps (“Y”s) on the demarc block. Remove any you
find.
3. If the problem persists, follow instructions in Base Station’s LED Solid Red or
Yellow, below.
4.7 Base Station LED Solid Red or Yellow
This indicates a short in the Base Station’s transmit or receive wire pairs, usually within a
pair.
Be sure none of the wires are shorted together. Remove the RJ-45 connector from the
Base Station. Remove the cable between the Interface Module and the demarc block.
Then use an ohmmeter to be sure there is an open circuit between pins on the RJ-45. If
you do not want to remove the cabling from the Interface Module (so you do not interfere
with system operation), remove the bridging clips on the demarc block for that Base
Station, then test with the ohmmeter.

5. Troubleshooting During Start-Up Phase
This section describes the sequence of the LEDs on all system cards when the system is
first powered on (Boot ROM and Download of software).
5.1 Boot ROM LEDs
When the system is powered on, the normal sequence is for the green LEDs to 'count' up
from 1 to 12 in binary. The following table outlines the sequence.
LEDs Code Description
0 0 Entered boot code
1 1 Done RAM test (check boot code CRC, flash type, factory page CRC,
downloaded CRC in that order)
2 2 Sent recognition character at 115200 (if carrier detected)
1,2 3 Sent recognition character at 57600 (if carrier detected)
3 4 Sent recognition character at 38400 (if carrier detected; send recognition
character at 9600 if carrier detected)
1,3 5 Jumping to downloader code
2,3 6 Entered downloader code
1,2,3 7 Copied to RAM, entered C code (check flash type, sense board slot,
check board type, CRC functional code, start IPC, in that order)
4 8 Checking for a KEEPALIVE message
1,4 9 Sent version to supervisor **
2,4 10 Awaiting download (sending requests if no other download) **
1,2,4 11 Jumping to functional code (functional code then blinks all the LEDs)
** Note: Codes 9 and 10 both blink at 1-second intervals while awaiting a response

5.3 Downloads
During downloads, either from the serial port or across the IPC, the green LEDs 'count'
up to show progress in the download. Each serial packet or IPC page increments the
count and it wraps to zero after getting to 31.
5.4 Configuration Changes
When changes are made to the configuration (Base Stations or Lines added or changed),
the information is sent from the System Controller to the Shelf Controller and Interface
Modules. Status LED
