troubleshooting steps to determine which piece of hardware is causing the continuous loop.

Identifying a Continuous/Boot Loop Due to a Wrong Iomem Size

The following symptoms might be observed on the console during the boot sequence:

Not enough memory in the system for IO memory

IO memory available 4110105 required 5242880 _> 2600

and/or

SYSTEM INIT: INSUFFICIENT MEMORY TO BOOT THE IMAGE!

and/or

Not enough memory in the system to run this image

Required pmem/iomem: 39435385/524288

*** System received a Software forced crash ***

Recovery Procedure

Step A

Use the 2600/3600/3700 Memory Calculator (

registered customers only

) to review the I/O and processor memory

requirements for your hardware configuration.

If your router doesn't have enough Dynamic RAM (DRAM) memory, go to Step D.•

If your router has enough DRAM memory, go to Step B.•

Step B

Follow the steps in the order outlined:

Turn the router off.1.

Remove all the Network Modules (NMs) and WAN Interface Cards (WICs) from the router.2.

Turn the router on.3.

If the router does not come up after removing the NM and WIC, go to Step C.

If it comes up fine, change the iomem configuration percentage as calculated by the 2600/3600/3700

Memory Calculator (

registered customers only

) .

Router#configure terminal

Router(config)#memory−size iomem 10

!−− The command above adjusts the percentage of DRAM to use for I/O Memory

Router(config)#exit

Router#copy running−config startup−config

Destination filename [startup−config]?

Building

[OK]

Router#

Turn the router off and reseat the NM and WIC cards.5.

Turn the router on. It should boot up fine with the NM and WIC cards.6.
