Not sure which topic to post this question so posting in LAN routing and switching topic:
Q1: Are these NME-WAE-502-K9 hot-swappable in Cisco 3845 routers?
Q2: One of my customers has several hundred 3845 routers with a NME-WAE-502-K9 module in each 3845 router.
Customer's requirement is when one of these NME-WAE-502-K9 fails at a remote site, our field engineer should replace the module and also upgrade the module to run image WAAS-22.214.171.124-K9.bin because customer will take ages to upgrade to this image which is over 400 MBytes, using a 512 Kbps/sec DSL line to this remote site.
I have some idea on how our field engineer can upgrade this module if a new NME-WAE-502-K9 is installed in a lab 3845 router by following the steps below:
Login to 3845 and go to enable mode:
ip address 10.1.1.1 255.255.255.0
!FTP server is on 10.1.1.2 with its default gateway being 10.1.1.1
ip address 10.1.2.1 255.255.255.0
service-module ip address 10.1.2.2 255.255.255.0
service-module ip default-gateway 10.1.2.1
Then telnet 10.1.2.2
Default credentials for new module
username is: admin
password is: default
copy ftp install <ftp-server-ip> / WAAS-4.1.1c.16-K9.bin
But if it is a production 3845 router with TACACS configured, when the field engineer telnet's to 10.1.2.2 ( NME-WAE-502-K9 module ) will TACACS ask for authentication even though the module is a new module.
I am not 100% sure on how the router hosts this module and the internal connections and how to maintain this unit to meet customer's requirement.
Any help and pointers to links appreciated.
BAsically I am looking for an answer on the R & R ( removal and replacement ) procedure of the NME-WAE-502-K9 module in a production 3845 router.
