cisco 2503 no serial interfaces in startup configuration

[meadowlake1205]

I bought a 2503 on ebay to help with remot access practic for the ccnp test. I had to do password recovery. When the configuration loaded I noticed the serial interfaces did not show up. whats even more puzzling is that the command show int ? only reveals options for bri and ethernet interfaces. It has two physical serial interfaces though. Is this a registry config problem or are the interfaces just dead. Any help is appreciated greatly.

Sounds like your router has started in boot mode. In boot mode, you'll get the prompt Router(boot)>. The bootstrap has a limited feature set and hence you may not see all your interfaces.

If you've got a valid IOS on the router, you can change your config register to boot into normal mode (0x2102):
Router(boot)> en
Router(boot)> config t
Router(boot)> config-register 0x2102

Save the config and reload the router. The router will boot into this mode by default if your system does not have a IOS in flash, or if you've changed the config-register to 0x2101. A "show version" will show you the current register setting. Check to see if you've still got an IOS image by doing a "show flash". If no file is present, you'll have to download a new IOS image.

Do you have two serial interfaces or two ports available? The interfaces won't show up unless you have a card in them.

baddos,
The 2503 he has comes with fixed serial interfaces. Not possible to insert additional cards in this model.

Jimmyzz,

Thanks for the advice. I don't recall seeing the Router
(boot) prompt at any time. I do have a flash file present but I wouldnt know if it were abnormal. This is it
System flash directory:
File Length Name/status
1 3491276 igs-g-l.111-2
The config register is set to 0x2102. Still I did try the steps you suggested and I appreciate the input. I was curious, on a fixed config model were all of the 2500 series
shipped with serial interfaces active and what would happen if they were bad? Would it be detected by the power on self
test?

Thanks in advance for any input.

Looks like you IOS image may not support the serial interfaces. Try downloading a new image if you've got access to the Cisco CCO area.
