Step 10 If a message appears indicating that the installation is not necessary, click Quit. The installer has detected that your installed software is the same version as the software to be installed. To force the installer to install the new software, uninstall the current software and then repeat this procedure.
These caveats have not been resolved:
•CSCin25042—Not getting DHCP address after resuming from sleep mode
When you are using the Mac OS 9.2.2 operating system, client adapters may not obtain an IP address using DHCP when resuming from sleep mode. This problem is caused by a design limitation in the operating system which causes potential DHCP timeouts to occur.
Workaround: You must manually reset the DHCP settings as shown below:
a. Open the TCP/IP Control Panel
b. In the popup menu, choose a type other than Using DHCP Server.
c. In the popup menu, choose Using DHCP Server.
d. Close the TCP/IP Control Panel.
•CSCin27041—Transmit powers shown incorrectly for PCI340
When you are using the ACU on the Mac OS 10.2 operating system, the transmit power levels are shown incorrectly for PCI 340 client adapters, but the power levels are shown correctly when you are using the Setup Assistant.
If you choose an incorrect power setting above 30 mW, the PCI 340 client adapter is limited to its maximum output power of 30 mW.
•CSCin28845—Not getting Gateway IP address when switching from AdHoc to Infrastructure
When you are using the Mac OS 9.2.2 operating system, the gateway IP address is not configured when changing a client adapter from AdHoc to Infrastructure mode.
Workaround: You must manually configure the Gateway IP address or reboot the Macintosh.
These caveats have been resolved for this release:
•CSCin26194—PCM 350 does not get IP address from DHCP with MIC
This is a duplicate of CSCin25042.
•CSCin28319—Client does not get IP address with MIC and different transmit key
When you are using the Mac OS 10.1.3 or 10.2 operating system, client adapters do not get an IP address from the DHCP server with MIC enabled and using different transmit keys on the client adapter and access point.
•CSCin28920—Resetting CB20A with WEP causes traffic to stop
When you are using the Mac OS 9.2.2 operating system, resetting the CB20A client adapter with WEP enable causes packet traffic to stop.
•CSCea38510—Memory leak in Mac OS X utilities
The memory leaks in the status and background utilities can cause the system to become very sluggish.
•CSCea86403—Macintosh drivers don't support 17 PowerBook series
The Macintosh driver and utility (version 3.0) do not work with the 17 inch PowerBook series products and can cause the system to lock-up.

TAC Case Priority Definitions
To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.
Priority 1 (P1)—Your 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.
Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operation 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.
Priority 3 (P3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
