NME-APA-E2 Cisco Application Performance Assurance Network Module, 80 GB, 1 GB

The NME-APA-E2 is the Cisco Application Performance Assurance network module for the Cisco 2811, 2821 and 2851 Integrated Services Routers. The module manages traffic flow using criteria such as business priorities, application or protocol recognition and user awareness. The NME-APA-E3 is the matching module for the Cisco 3825 and 3845.

The NME-APA-E2 ships with an 80 GB SATA hard disk and 1 GB of memory, and it has no compact flash. The USB port and the external RJ-45 connector are not used, and Cisco recommends making no connection to the RJ-45. Gigabit Ethernet is not supported, and the LINK and ACT LEDs are unused.

The module holds a hard disk and needs a graceful shutdown before power is removed: press the Reset button for less than 1 second, or use the service-module command. The application can take 3 minutes to shut down fully, and holding the button for more than 4 seconds forces a non-graceful disk shutdown that may corrupt files. Unlike the NME-APA-E3 in a 3845, the NME-APA-E2 needs the router powered off before it is inserted or removed. The module keeps its own configuration file, separate from the router, and that file should be saved before the module is swapped. Cisco interface cards holds the other router modules.
