Firmware Installation Procedure

Firmware Upgrade Issues

If you are currently running firmware 6.0(2) to 7.0(2) on a Cisco Unified IP Phone 7961G/7961G-GE or 7941G/7941G-GE and want to upgrade to 8.0(x), be aware that upgrading will take up to twice as long to complete as usual.

Firmware Installation Procedure

Before using the Cisco Unified IP Phone 7961G/7961G-GE or 7941G/7941G-GE with Cisco Unified CallManager 5.0, you must install the latest firmware on all Cisco Unified CallManager servers in the cluster.

To download and install the firmware, follow these steps:

Procedure


Step 1 Go to the following URL:

http://www.cisco.com/cgi-bin/tablebuild.pl/ip-7900ser

Step 2 Double-click the following hyperlink, and follow the prompts to download the firmware:

cmterm-7941_7961-sip.8.0.2SR1.cop

Step 3 Go back to the URL shown in Step 1, double-click one of the following hyperlinks, and follow the prompts to download the Readme file, which contains installation instructions for the corresponding firmware:

cmterm-7941_7961-sip.8-0-2SR1-readme.htm

Step 4 Follow the instructions in the Readme file to install the firmware.


Important Notes

Failover Time Using TCP is Faster than Failover Time with UDP

Cisco Unified CallManager Load Server Setting for Firmware Upgrades

Secure PC Log Off in an 802.1X Network

Failover Time Using TCP is Faster than Failover Time with UDP

You can configure SIP profiles for the Cisco Unified IP Phone 7961G/7961G-GE and 7941G/7941G-GE to operate with TCP or UDP by using the SIP Phone Security Profile Configuration window in Cisco Unified CallManager Administration. If you select TCP as a transport protocol, the failover time between primary, secondary, and tertiary Cisco Unified CallManagers is approximately 5 seconds or less. If you select UDP, the failover time is approximately 120 seconds. The failover time is the maximum time that the phone waits before it can detect Cisco Unified CallManager failure status. The difference in the failover times is due to the behavior of TCP and UDP and is not a defect on the Cisco Unified IP Phones or Cisco Unified CallManager.

Cisco Unified CallManager Load Server Setting for Firmware Upgrades

Cisco Unified CallManager Administration contains a setting to optimize installation time for phone firmware upgrades.


Note The setting is intended for future use, and is not yet a supported feature on SIP phones.


The Load Server setting is visible on the Phone Configuration page (Product Specific Configuration section) in the Cisco Unified CallManager Administration application. This setting lets you specify another TFTP server IP address or name (other than the TFTP Server 1 or TFTP Server 2) from which the phone firmware can be retrieved for upgrades on the phones. When the Load Server is set, the phone contacts the designated server for the firmware upgrade.


NoteIf the firmware load is not found on the Load Server, the phone does not upgrade and is not redirected to the TFTP Server 1 or TFTP Server 2.

On a factory reset or during a software recovery operation, the phone may fall back to using TFTP Server 1 or TFTP Server 2 to recover the phone load. In these scenarios, the phone will recover the phone load either via the term61.default.loads or term41.default.loads file, or it will attempt to recover the phone load based on its load.hist file.

If the phone is auto-registering with Cisco Unified CallManager for the first time, the phone will request the phone load via TFTP Server 1 or TFTP Server 2. This will only occur once when the phone is first installed into the system. This can be mitigated by preloading the phones with the correct firmware so that no firmware upgrade is required in combination with the auto-registration, or by auto-registering the phones at the main site prior to deployment at a remote site.


You can view the Load Server setting on the phone from Settings > Device Configuration > Network Configuration > Load Server. If the value in the Load Server setting is invalid, a "Load Server is invalid" message is displayed on the phone in Settings > Status > Status Messages.

Secure PC Log Off in an 802.1X Network

Firmware release 8.0(2) SR1 provides support for a Cisco Unified IP Phone 7961G/7961G-GE and 7941G/7941G-GE to monitor IEEE 802.1X messages between an authenticating switch and a connected PC (supplicant).

When a PC is disconnected from the Cisco IP Phone, the phone issues an EAPOL-Logoff message on behalf of the PC to the authenticating switch. The proxy EAPOL-Logoff message causes the authenticating switch to set the port to an unauthenticated state.

If you have an 802.1X network and upgrade to Cisco Unified IP Phone firmware release 7.0(2) or greater, be aware that you must re-authenticate a PC that is connected to a Cisco Unified IP Phone 7961G/7961G-GE and 7941G/7941G-GE.

For more information about 802.1X re-authentication, refer to the Cisco Catalyst switch configuration guides at:

http://www.cisco.com/en/US/products/hw/switches/tsd_products_support_category_home.html

Submitting a Service Request

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:

http://www.cisco.com/techsupport/servicerequest

For S1 or S2 service requests, or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—An existing network is down, or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of the network is impaired, while most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
