Conventions

Refer to Cisco Technical Tips Conventions for more information on document conventions.

Use the Current Release

For optimal performance, use the most current release of the software. The current release is:

  • P005W301

Hard Set the Ethernet Port

Complete these steps to hard set the Ethernet port:

  1. Press Menu.

  2. Use the down arrow to navigate to Admin Setup and press Select.

  3. Enter the default passcode of **# and press the Enter softkey.

  4. Use the down arrow to navigate to Ethernet Port Configuration and press Select.

  7. The phone reboots.

Hard Set the Port on the Switch

Hard set the port on the switch to which the Cisco 7935 IP Conference Phone connects to 10 Mbps/half-duplex.

Issue these commands to hard set the port on the switch for Catalyst 2900XL and 3500XL products:

  • configure terminal

  • interface 0/x

  • speed 10

  • duplex half

  • end

Issue these commands to hard set the port on the switch for Catalyst 4xxx, 5xxx, and 6xxx products:

  • set port speed x/y 10

  • set port duplex x/y half

Remove Voice or Auxiliary VLAN References

Since the Cisco 7935 IP Conference Phone has no 10/100 port to which to connect a PC as other 7900 Series IP Phones do, the concept of a voice or auxiliary VLAN does not directly apply and can cause problems. Remove references to the voice VLAN or auxiliary VLAN from the port on the switch that the Cisco 7935 connects to, and put that port in the VLAN whose number corresponds with that of the voice VLAN to avoid potential problems.

Issue these commands to remove voice or auxiliary VLAN references for Catalyst 2900XL and 3500XL products:

  • configure terminal

  • interface 0/x

  • switchport access vlan z

  • no switchport voice vlan z

  • no switchport mode trunk

  • no switchport trunk encapsulation dot1q

  • end

Issue these commands to remove voice or auxiliary VLAN references for Catalyst 4xxx, 5xxx, and 6xxx products:

  • set port auxiliaryvlan x/y none

  • set vlan z x/y

  • set trunk x/y off
