SM-ES2-24-P - Connection refused by remote host

[Michael Durham]

I bought a used 2911 router and it came with a SM-ES2-24-P switch and I would like to get into its configuration so I could use it.  But every time I enter the command Router#service gigabitethernet1/0 session, I get this error:

Trying 192.168.202.1, 2067 ...
% Connection refused by remote host

I have tried Router#service gigabitethernet1/0 password-reset six times but it will not let me in.  Here is the results:
Router#service gigabitethernet1/0 password-reset
Do you want to proceed with password reset process?[confirm]

I do not care about any configs on the switch, I just need to reset it to factory an d start over. I have spent six hours trying and researching this.  All suggestions welcomed!

I do see this error message from time to time:

Jun 6 17:34:31.636: %CDP-4-NATIVE_VLAN_MISMATCH: Native VLAN mismatch discovered on GigabitEthernet1/1 (1), with USSWTVIN926.kellwood.com GigabitEthernet0/17 (133).

Here is my config:

!
interface GigabitEthernet1/0
ip address 192.168.202.1 255.255.255.0
!
interface GigabitEthernet1/1
no ip address

I found the answer:
Issue a service-module gigabitEthernet 1/0 Status command.

Router#service-module gigabitEthernet 1/0 Status
Service Module is Cisco GigabitEthernet1/0
Service Module supports session via TTY line 67
Service Module is in Steady state
Service Module reset on error is disabled
Service Module heartbeat-reset is enabled
Getting status from the Service Module, please wait..

EtherSwitch Service Module with 1 GE and 23 FE PoE ports
System name = Switch
Model string = SM-ES2-24-P
System board ID = 0xE4
Base MAC addr = 1833.9dd0.2a00
Switch number = 1
System uptime = 0 days, 7 hours, 47 minutes, 15 seconds

Software Details:
Operating System = Cisco c2960sm IOS Software
Version = 12.2(52)EX1
Major Version = 1
Minor Version = 42
Image path = flash:/c2960sm-lanbasek9-mz.122-52.EX1.bin

Look at the Service Module supports session via TTY line 67. Depending on which module you have installed the line number may be different; but that is the number that you need to know.

On the router issue these commands:

line 67
password Cisco
no activation-character
no exec
transport preferred none
transport input all
transport output all
stopbits 1
flowcontrol software

Now you can issue service-module gigabitEthernet 1/0 session command and you can get in.
