Installare IOS su Catalyst 2900XL

[carve81]

Ciao

Io avrei bisogno di installare un IOS su un Catalyst 2900XL.
Lo switch è attualmente completamente vuoto (anche la flash).
Non trovo da nessuna parte come fare a caricare dal mio PC (dove ho scaricato qualche IOS) allo switch.

Qualcuno sa darmi una dritta?
Grazie

hyperterminal configurato a 9600baud, cavo console connesso alla seriale del pc.
Accendi lo switch e dopo poco dovresti trovarlo in rommon.
A quel punto esegui la procedura di xmodem (o ymodem) e gli mandi il file.
Il consiglio è quello di modificare la velocità della porta console e metterla a 115200 (altrimenti l'upload sarà lentissimo).

Cmq, preso da una pagina cisco:

"From Cisco's Website:

Introduction
This document describes how to recover from a corrupt or missing software
image on the Cisco Catalyst 2900XL and 3500XL Series Switches. When this
problem exists, the error message error loading flash appears when you boot
up after power loss or after an incorrect software upgrade.

Note: Trivial File Transfer Protocol (TFTP) may be used to transfer software
image files from a PC to your device. This document was written using output
from the Cisco TFTP server application. Cisco has discontinued this
application and no longer supports it. If you do not have a TFTP server,
obtain any third-party TFTP server application from another source.

Prerequisites
Requirements
There are no specific requirements for this document.

Components Used
To create the examples in this document, this equipment is used:

Hyperterminal software used in Microsoft Operating Systems.

A console cable suitable for the Catalyst 2900XL / 3500XL in the switch.

The information presented in this document was created from devices in a
specific lab environment. All of the devices used in this document started
with a cleared (default) configuration. If you are working in a live
network, ensure that you understand the potential impact of any command
before using it.

Conventions
For more information on document conventions, refer to the Cisco Technical
Tips Conventions.

Problem
If you receive the error loading flash message, this indicates that there is
a problem loading the current image in Flash. The image may be corrupt, an
incorrect image, or the image in Flash may be missing. If the system is
unable to load a software image in Flash, the system loads the boot helper
and brings up a switch: prompt. Otherwise it is in a continuous boot cycle.
If the switch is stuck in a continuous boot cycle, use this procedure to
bring up a switch: prompt:

Unplug the power cable.

Hold down the mode button located on the left side of the front panel while
you reconnect the power cord to the switch. Release the mode button a second
or two after the LED above port 1x is no longer illuminated.

Enter the commands flash_init and load_helper.

This problem occurs only on XL switches. For a complete list of affected
switches, see the XL Models, Their Amount of Memory, and Category of Images
They Support section of this document.

This is a sample output from a failed bootup:

Solution
(Section A) Verify Software Image in Flash and Attempt to Manually Boot
Process
Follow these steps when you verify the software image in Flash and attempt
to boot manually.

Connect a terminal to the console port of the switch.

In the absence of software image or with corrupted image, the software image
does not load.

The switch starts in boot loader mode. This is indicated by the switch:
prompt

Verify the software contents of Flash by issuing the dir flash: command.

switch: dir flash:
Directory of flash:/

189 -rwx 856 <date> vlan.dat
3 -rwx 1112393 <date> c2900XL-h2-mz-112.8.5-SA6.bin

Verify that the image in Flash is the correct image for the platform. The
hardware model number is on the front of the switch. For information on how
to verify the image, refer to the Catalyst 2900XL and 3500XL section of
Managing Software Images and Working with Configuration Files on Catalyst
Switches.

Note the hardware model here.

For Standard / Enterprise Edition hardware, the image name must contain the
suffix "h2".

For Original Edition hardware, the image name must contain the suffix "h"
and not "h2".

If the software image present is incorrect for the switch, or if it is
missing, proceed to (Section B) Copy a New Software Image from ROM Monitor.

If the software image in Flash is correct, manually boot this software image
with the help of the boot flash:<filename> command.

switch: boot flash:c2900XL-h2s-mz-120.5-XP.bin


If the system boots correctly and does not return to the switch: prompt,
proceed to (Section C) Change and Verify Boot Configuration.

If the system still fails to load the image correctly, proceed to (Section
B) Copy a New Software Image from ROM Monitor.


(Section B) Copy a New Software Image from ROM Monitor
To copy a new software image from a ROMmon follow these steps. For
additional documentation on this procedure, refer to Recovering Catalyst
2950, 2955, and 3550 Series Switches from a Corrupted or Missing Image.

Check the remaining memory capacity. If the size of the file to be loaded is
larger than the available capacity, delete the existing image in Flash to
make space for a new image.

The command to delete the existing image in Flash is delete flash: filname ,
where filename is the name of the file to be deleted. A sample command
output is shown here.

delete flash:cat2900XL-h2s-mz.112-8.5-SA6.bin

Download a new Cisco IOS-only image file from the Cisco Software Center (
registered customers only) to your PC. Do not download a Cisco IOS image
with Cluster Management Suite (CMS) files. Xmodem transfer is a very slow
procedure. It takes longer to copy the larger images.

Copy the image to the Flash using HyperTerminal for Microsoft Windows, or
another terminal software program. The command on the switch is copy xmodem:
flash:filename , where filename is the name of file that you downloaded.
With HyperTerminal, use the TRANSFER -- SEND FILE option using the XMODEM
protocol. Start the XMODEM download within three seconds. Otherwise, the
switch times out the XMODEM copy.

When the XMODEM request appears, issue the appropriate command on the
terminal-emulation software to start the transfer. Copy the software image
into Flash memory. The command to issue is switch: copy xmodem:
flash:image_filename .

An example is shown here.

switch:
switch: copy xmodem: flash:c3500XL-c3h2s-mz.120-5.1.XP.bin

CCC............................................... ...........................

(BEGIN XMODEM DOWNLOAD ON TERMINAL SOFTWARE NOW)

File "xmodem:" successfully copied to
"flash:c3500XL-c3h2s-mz.120-5.1.XP.bin"
After the new image has been loaded, boot the new image using the boot
flash:filname command where filename is the name of the file that is
downloaded. A sample command output is shown here.

boot flash:c2900XL-hs-mz.112-8.6-SA6.bin

After you boot the system, download a bundled image. For information on how
to download a bundled image (.tar), refer to Upgrading Software in Catalyst
2900XL and 3500XL Switches Using the Command Line Interface.

Note: The .tar file on Cisco.com is named c3500XL-c3h2s-mz-120_5_1-XP .tar.
The Cisco IOS file inside is called c3500XL-c3h2s-mz-120.5.1-XP.bin.

When you follow the upgrade instructions in the above link, the old image is
renamed using an underscore. The new image is copied into Flash. Instead of
the new image overwriting the old one, the result is two images, one old and
one new. Reloading this causes the XL series switch to reload to the old
image (now confusingly called by the new name in Flash).

The problem is overcome by renaming the .tar file downloaded from Cisco.com
to the exact same name as the .bin file enclosed within it.

After you upgrade from Cisco IOS Software Release 11.2 to Cisco IOS Software
Release 12.0.5(1), there is a file left in Flash named
c3500XL-diag-mz-112.8.2-SA6. The box now runs Cisco IOS Software Release
12.0. There is no similar diag file for Cisco IOS Software Release 12.0. The
Cisco IOS Software Release 11.2 diag file is useless and can be deleted.

(Section C) Change and Verify Boot Configuration
Follow these steps when you change and verify the boot configuration.

Enter enable mode by issuing the enable command. View the boot configuration
by issuing the show boot command. A sample command output is shown here.

Switch#: show boot
BOOT path-list: Flash:c3500XL-c3h2s-mz-120.5.1-XP.bin

Config file: Flash:config.text E

Enable Break: no

Manual Boot: no

HELPER path-list:

NVRAM / Config file

buffer size: 32768
Verify that the boot configuration is correct by viewing the contents of
Flash. Issue the dir flash: command to view the boot configuration.

Switch# dir flash:
Directory of Flash:/

189 -rwx 856 <date> vlan.dat
4 drwx 10816 <date> html
2 -rwx 106 <date> info
175 -rwx 1490584 <date> c2900XL-h2s-mz-120.5-XP.bin
176 -r-- 302 <date> env_vars
174 -rwx 106 <date> info.ver
177 -r-- 1306 <date> config.text
499200 bytes available (3113472 bytes used)
If the boot variable is not correct, change the boot variable by entering
the global configuration mode and issuing the command boot system
flash:filename , where filename is the name of the image to boot.

Save the configuration by issuing the write memory command. Verify the boot
parameter by issuing the show boot command.

The switch boots automatically the next time that the switch is reloaded.

Si grazie avevo appena risolto...

Giusto perche magari sia utile ad altri:
Ho risolto scaricando da internet il .bin (tralasciamo le fonti ;-)) in locale
Apro connessione HyperTerminal sulla console dello switch.
Il prompt è come il seguente:

switch:


A questo prima dal menu di HyperTerminal faccio "Invia file" e selezionando Xmodem e il file .bin predispongo l'invio del bin.
Subito dopo da linea di comando:

switch: copy xmodem:xxxxxxx.bin flash:xxxxxxxxx.bin

Parte l'invio del file che verrà salvato nella flash.
Ora ho fatto il boot della flash:

switch: boot flash:xxxxxx.bin

Lo switch riparte.
