Version 2.0.1 15 May 2013
Problem / LCD Notification
Corrective Action
LCD Notification:
"Location look-up failed.
Please enter your address."
 Make sure that 'Location look up' is configured by
the management shell in the Lync server.
LCD Notification:
"LAN Link failure"
The LAN link is disconnected. This is a general
networking problem that's beyond the scope of this
document. Either there's a physical cabling issue or
there's a local or VLAN communications problem.
LCD Notification:
"Duplicate IP"
This is a general networking problem. The IP address
configured for this endpoint was already configured
for another.
 In the DHCP server, delete the duplicate IP
address and request another.
LCD Notification:
"Failed to connect to Lync server"
This is a general networking problem beyond the
scope of this document. If a communications problem
occurs in the enterprise network, for example, if the
server goes down, this notification is displayed on the
phone LCD.
LCD Notification:
"PIN invalid phone info"
The phone number or extension that was entered is
invalid.
 Make sure that the correct information was entered
in the phone LCD and in the Lync server interface,
and that they tally.
 Verify in the Lync server interface that the PIN is
enabled and if it isn't, enable it.
LCD Notification:
"PIN not set"
 Verify in the Lync server interface that a PIN was
configured for this user account.
 If it wasn't, create a PIN for the account.
LCD Notification:
"PIN expired"
 In the Lync server interface, renew the PIN
expiration policy.
LCD Notification:
"PIN account disabled"
 Verify in the Lync server interface that the account
was enabled. If it wasn't, enable it.
LCD Notification:
"PIN internal error"
 Test the PIN Authentication process on the Lync
server: Run in the server shell the emulate cmdlet:
Test-CsPhoneBootstrap -PhoneOrExt nnnn -PIN nnnn
 If the test result is 'fail', there's a configuration
error on the Lync server side, hence the PIN sign-
in failure on the phone side. To troubleshoot, see:

Note:
 The ringer LED remains red until the problem is corrected.
 Users cannot dial or initiate calls if an LCD notification is displayed.
