Loading IOS on a WS-X45-SUP7L-E from ROMMON

This is how to load an IOS image on a WS-X45-SUP7L-E (probably works for other SUPs as well) from the ROMMON> prompt via TFTP and (optionally) installing it afterwards.

• Connect to the serial console of the SUP
• Connect the MGMT interface of the SUP to the network
• Turn on the chassis and wait for the device to stop at the ROMMON> prompt
• Configure network connectivity from ROMMON (IPs are just examples)
  • set ip route default 192.168.1.254
  • set interface fa1 192.168.1.249 255.255.255.0
  • Test connectivity: ping 192.168.1.11
• Boot IOS image via network (TFTP)
  • boot tftp://192.168.1.11/cat4500e-universalk9.SPA.03.04.00.SG.151-2.SG.bin
• Configure network connectivity from within IOS (IPs are just examples)
  • Enter configuration mode
  • interface FastEthernet 1
  • ip address 192.168.1.249 255.255.255.0
  • no shutdown
  • Test connectivity: ping vrf mgmtVrf 192.168.1.11 (check vrf name first)
• Format boot flash: format bootflash:
• Define interface to be used for TFTP protocol:
  • Enter configuration mode
  • ip tftp source-interface FastEthernet 1
• Copy IOS image to bootflash
  • copy tftp: bootflash:
