Adding Telephones 131 3Com Entry Telephones The 3Com 3100 Entry Telephone does not have a display panel to show the status of the process of initializing the telephone when you connect it to an NBX system or when you reboot the phone of the NBX system. However, the 3100 Entry Telephone indicates its status by displaying a series of blinking patterns using its message waiting indicator light. Table 30 describes the 3100 Entry Telephone initialization states. Table 30 3100 Entry Telephone Initialization Status Blink Pattern 2 blinks in 2 seconds Pause 2 seconds Repeat 3 blinks in 3 seconds Pause 2 seconds Repeat Continuous slow blinks with no pause 3 blinks in 1.5 seconds Pause 2 seconds Repeat Telephone State Notes The 3100 is searching for an NBX system using a Layer 2 protocol No action required. If the 3100 does not find an NBX system using Layer 2, it will search for an NBX system using a Layer 3 protocol. The 3100 is searching for The 3100 will start using an NBX system using a Layer 3 after it has received IP Layer 2 protocol configuration information from a DHCP server. The 3100 has detected an NBX system using a Layer 2 protocol. If this pattern persists, it could indicate that the device is not in the NBX database. You should use the NBX NetSet utility to add the device to the system. The 3100 is trying to obtain IP information from a DHCP Server. If it is successful the pattern will change to Layer 3 Discovery. If DHCP configuration fails then the 3100 pattern will temporarily indicate DHCP Failure, described below. If this state persists for 20 or more seconds then the device is not able to detect a DHCP server. If this state ends and the device transitions to DHCP Failure, and the device is expected to utilize DHCP, then the DHCP offer is incorrect or missing Option-184 information. Correct the DHCP configuration or program IP information into the 3100 using the 3Com Telephone Local Configuration tool, which is described in the NBX Administrator's Guide.
