Protective Cover Cases

Phone cover cases provide extra protection for the phone in special environments such as these:

Healthcare—Cover cases keep liquids and other substances on hands from contaminating the phone. You can disinfect the phone cover case while protecting the phone from moisture.

Manufacturing—Heavy-duty cover cases protect phones from dust, electro-static discharge (ESD), and provide drop protection.

Retail and Service—Cover cases keep the phone free from moisture, hair, and dust, and protect against hard impacts from dropping a phone.


Note You can invalidate the one-year hardware warranty by not adequately protecting your phone from moisture, contaminants, or hard impacts from dropping the phone.


You can order protective cover cases from these suppliers:

System Wear provides a heavy duty vinyl case which can be cleaned or disinfected. It is ideal for healthcare, manufacturing or retail environments where drop protection is important.

Order from System Wear at www.systemwear.com

zCover makes a silicon cover case for phones that need to be cleaned or disinfected.

Order from zCover at www.zcover.com

Standard Wired Earbud

Guidelines for Using Accessories and the Phone

Follow these guidelines when using accessories and your Cisco Unified Wireless IP Phone 7920:

Use only chargers, batteries, and accessories that are approved by the Cisco Unified Wireless IP Phone 7920 manufacturer.

Do not adhere a clip to the back of the phone or insert a clip between the phone and battery cover because it can damage the battery.

Use a protective cover case to shield the phone from moisture, dust, hair, grease, and other contaminants that might get on your hands. For example, in Healthcare environments, where phones must be cleaned with sterilizing wipes, you must use a protective cover case to prevent moisture damage to the phone.

Use a protective cover case in environments where the phone might be bumped or dropped, such as manufacturing or warehouse environments.

When disconnecting the power cord of any accessory, grasp and pull the plug. Do not pull the cord.

Clean the phone only with a soft dry cloth. Do not use moist wipes or cleaning powders that might damage the phone.


Note Using unapproved accessories, not protecting the phone from moisture, contaminants, and hard impacts can invalidate the one-year hardware warranty on the phone.

Reporting Security Problems in Cisco Products

Cisco is committed to delivering secure products. We test our products internally before we release them, and we strive to correct all vulnerabilities quickly. If you think that you have identified a vulnerability in a Cisco product, contact PSIRT:

For emergencies only — security-alert@cisco.com

An emergency is either a condition in which a system is under active attack or a condition for which a severe and urgent security vulnerability should be reported. All other conditions are considered nonemergencies.

For nonemergencies — psirt@cisco.com

In an emergency, you can also reach PSIRT by telephone:

1 877 228-7302

1 408 525-6532


Tip We encourage you to use Pretty Good Privacy (PGP) or a compatible product (for example, GnuPG) to encrypt any sensitive information that you send to Cisco. PSIRT can work with information that has been encrypted with PGP versions 2.x through 9.x.

Never use a revoked encryption key or an expired encryption key. The correct public key to use in your correspondence with PSIRT is the one linked in the Contact Summary section of the Security Vulnerability Policy page at this URL:

http://www.cisco.com/en/US/products/products_security_vulnerability_policy.html

The link on this page has the current PGP key ID in use.

If you do not have or use PGP, contact PSIRT to find other means of encrypting the data before sending any sensitive material.

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
USA: 1 800 553 2447

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.
