View source for Loading IOS on a Switch or Router

'''''This article describes the procedure of loading IOS on a Router or a Switch using a RJ-45 ethernet cable.<br/> 
'''''You need a console connection and a TFTP-Server connection. Make sure the TFTP server is using the right IP address.'''''<br/>
'''''Make also sure the IOS is available in the right TFTP Server Root directory. (normally C:\TFTP-Root)'''''<br/>
'''''We recommend the Solarwinds TFTP Server.''''' http://www.solarwinds.com/downloads/  <br/>
'''''Apart from Step 2 the procedure is the same for a switch and a router.'''''<br/>
'''''Pay attention connecting a Router with a cross over cable, when connecting directly to your PC.'''''<br/>
'''''When connecting a Swtich to your PC you need a straight through cable. '''''<br/>
'''''PC's of recent generations won't have a Problemn switching even when using a straight through cable with a router.'''''

'''Step 1:''' reset password<br/> 

'''Step 2:''' assign an IP address to the switch or to the interface through which you are connecting to the router (eg: 10.0.0.1 255.255.255.0):<br/> 

Switch>'''en'''<br/> 
Switch#'''configure terminal'''<br/> 
Switch(config)#'''interface vlan 1'''<br/> 
Switch(config-if)#'''ip address 10.0.0.1 255.255.255.0'''<br/> 
Switch(config-if)#'''exit'''<br/> 
Switch(config)#'''exit'''<br/> 
Switch#<br/>

or<br/>

Router>'''en'''<br/> 
Router#'''configure terminal'''<br/> 
Router(config)#'''interface gigabitEthernet 0/1'''<br/> 
Router(config-if)#'''ip address 10.0.0.1 255.255.255.0'''<br/> 
Router(config-if)#'''exit'''<br/> 
Router(config)#'''exit'''


'''Step 3:''' format flash:  MAKE SURE YOU HAVE A TFTP CONNECTION BEFORE FORMATING THE FLASH<br/> 

Switch#'''format flash:'''<br/> 
Format operation may take a while. Continue? [confirm]  '''''hit enter'''''<br/> 
Format operation will destroy all data in "flash:".  Continue? [confirm]   '''''hit enter'''''<br/> 
flashfs[1]: 0 files, 1 directories<br/> 
flashfs[1]: 0 orphaned files, 0 orphaned directories<br/> 
flashfs[1]: Total bytes: 3612672<br/> 
flashfs[1]: Bytes used: 1024<br/> 
flashfs[1]: Bytes available: 3611648<br/> 
flashfs[1]: flashfs fsck took 3 seconds.<br/> 
Format of flash: complete<br/> 
Switch#<br/> 


'''Step 4:''' copy from tftp to flash<br/> 

Switch#'''copy tftp: flash:'''<br/> 
Address or name of remote host []? '''10.0.0.2'''<br/> 
Source filename []? '''c3500xl-c3h2s-mz.120-5.WC16.bin'''<br/> 
Destination filename [c3500xl-c3h2s-mz.120-5.WC16.bin]?   '''''hit enter'''''<br/> 
Accessing tftp://10.0.0.2/c3500xl-c3h2s-mz.120-5.WC16.bin...<br/> 
Loading c3500xl-c3h2s-mz.120-5.WC16.bin from 10.0.0.2 (via VLAN1): !!!!!!!!!!!!!<br/>

[OK - 1811507 bytes]<br/> 

1811507 bytes copied in 104.315 secs (17418 bytes/sec)<br/> 
Switch#<br/> 


'''Step 5:''' make sure the IOS has been loaded on the switch<br/> 

Switch#'''dir'''<br/> 
Directory of flash:/<br/> 

  2  -rwx     1811507   Mar 01 1993 00:14:06  c3500xl-c3h2s-mz.120-5.WC16.bin<br/> 

3612672 bytes total (1799680 bytes free)<br/> 
Switch#<br/> 


'''Step 6:''' delete the config<br/> 

Switch#'''wr erase'''<br/> 
Erasing the nvram filesystem will remove all files! Continue? [confirm]  '''''hit enter'''''<br/> 
[OK]<br/> 
Erase of nvram: complete<br/> 
Switch#<br/> 


'''Step 7:''' reload<br/> 
Switch#'''reload'''<br/> 

System configuration has been modified. Save? [yes/no]: '''no'''<br/> 
Proceed with reload? [confirm]   '''''hit enter'''''<br/> 

'''you're done'''
