TROUBLESHOOTING AND CARE
5 Troubleshooting and Care
This section covers troubleshooting and caring for your IP250D.
5.1 BASIC TROUBLESHOOTING MEASURES
If the IP250D does not seem to function as expected, there are several troubleshooting techniques that may be tried before contacting the network administrator.
| 5.1.1 Disconnect From the Network | ||
| Unplug the network patch cable from the wall jack. Wait at least fifteen (15) seconds, | ||
| then plug the cable back into the same jack. The IP250D will attempt to | ||
| contact with the SIP server or Call Agent. In many cases of malfunction, this should | ||
| restore normal operation. | ||
! |
| ||
Warning: Risk of electrical shock! Dangerous voltages may be present on the exposed | |||
terminals of the network patch cable after it is plugged into the network wall jack. | |||
WARNING | |||
| 5.1.2 Disconnect the PC | ||
| If there is a PC or other network device connected to the “PC” network port, disconnect | ||
| the patch cable to the PC from the base of the keyset, then perform the actions from sec- | ||
| tion 5.1.1, Disconnect From the Network. | ||
| 5.1.3 Check the Cords and Cables | ||
| If the previous two steps do not solve the problem, all of the cords and cables (including | ||
| handset cord and headsets) should be disconnected, inspected for dirt or corrosion, and | ||
| reconnected. |
