The external RJ-45 connector on the NME-APA is not supported at this time; we recommend that you
do not make any connections to it.
Online Insertion and Removal of NME-APA-E3
Only Cisco 3845 Integrated Services Routers (ISRs) allow replacing NME-APA-E3 modules without
first removing power from the router. This ability is called online insertion and removal (OIR). While
traffic monitoring stops during a module's removal, OIR provides uninterrupted network connectivity.
Enhanced network modules contain hard disks that require graceful shutdown. Removing a module
without graceful shutdown may result in disk file corruption.
Caution Before removing power from the router or starting an online insertion and removal (OIR) sequence,
perform a graceful shutdown by pressing the Reset button on the network module for less than
1 second, or using an appropriate CLI command.
OIR operates only with modules that are the same type. If you remove a module, install another

module exactly like it in its place. If you remove a 2-slot module (along with any installed WAN or
voice interface cards), install another module and card combination exactly like it.
For descriptions of informational and error messages that may appear on the console during this
procedure, see the hardware installation guide for your router.
Saving the NME-APA Configuration File
The NME-APA has its own configuration file which is separate from that of the router. Save the existing
configuration file before you replace the module to ensure that the new module will operate exactly as
the old module did.
To perform online removal of a network module and insertion of a replacement, follow these steps in
privileged EXEC mode:
Telnet to the NME-APA:
Step 1
Router# telnet 10.10.10.2
Trying 10.10.10.2...
Connected to 10.10.10.2.
