Upgrading a Dell Sw Stack of 4 units 5548

I have a Dell  Stack of 4 units 5548, and I want to upgrade it, The matter is  that when I Upgraded the Master Unit I thought that all the units would be upgraded, but Just the master Units was upgraded.

What I would like to know is, If are there any commands I can uses for upgrading the complete stack. ? 

Thanks.

Re: Upgrading a Dell Sw Stack of 4 units 5548

The firmware download includes a pdf which details the process of updating the firmware on a stack. Here are those instructions.

1. Connect to the serial port (default setting 9600 baud, 8 data bits, no start bits, 1 stop bits)

and enter the CLI mode. The following prompt is displayed:

console>

2. Ensure that an IP address is assigned to at least one port on the switch. Use the following

commands to assign an IP address to vlan 1 (this example uses IP address 10.10.10.101).

console> enable

console# config

console(config)# interface vlan 1

console(config-if)#ip address 10.10.10.101 /24

console(config-if)#exit

3. Enter console#copy tftp://{tftp address}/{file name} unit://*/image to copy the

software to all the switches in the stack. The software is copied but does not become active

until the file is selected as the active image file and the switches are reset. The following is

an example of the information that is displayed:

console# copy tftp://10.10.10.100/powerconnect_5500-41020.ros unit://*/image

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

11-Oct-2006 16:40:07 %COPY-N-TRAP: The copy operation was

completed successfully

console#

4.Enter console#copy tftp://{tftp address}/{file name} unit://*/boot to copy the

boot software to the switch. The boot software is copied but does not become active until the

switch is reset. The following is an example of the information that is displayed:

console# tftp://10.10.10.100/powerconnect_55XX_boot-10014.rfb unit://*/boot

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

console#

5. Enter console# show bootvar to verify which image is active. The following is an example

of the information which is displayed:

console# show bootvar

Unit Image Filename Version Date Status

---- ----- --------- --------- --------------------- -----------

1 1 image-1 4.1.0.20 18-Aug-2015 11:35:45 Not active

1 2 image-2 4.1.0.16 17-Mar-2014 15:16:29 Active*

2 1 image-1 4.1.0.20 18-Aug-2015 11:35:45 Not active

2 2 image-2 4.1.0.16 17-Mar-2014 15:16:29 Active*

3 1 image-1 4.1.0.20 18-Aug-2015 11:35:45 Not active

3 2 image-2 4.1.0.16 17-Mar-2014 15:16:29 Active*

"*" designates that the image was selected for the next boot

6. When new software is downloaded, it goes to the “not active” images on each of the stack

switches. Since image-1 has the new software on unit 1 (the Not active image), enter

console# boot system image-1 switch-1 to boot from image-1. Since image-1 has the

new image on unit 2 (the Not active image), enter console# boot system image-1

switch-2 to boot from image-1. Since image-1 has the new software on unit 3 (the Not

active image), enter console# boot system image-1 switch-3 to boot from image-1.

console# boot system image-1 switch 1

console# boot system image-1 switch 2

console# boot system image-1 switch 3

We can also use below command to boot from image-1 on all switches instead of doing

separately for all switches.

console# boot system image-1 all

7. Type reload. The following message is displayed:

console# reload

This command will reset the whole system and disconnect your current session.

Do you want to continue (y/n)[n]?

8. Type Y. The switch reboots

9. Enter console# show version to verify that the new software version is currently running

on each unit. The following is an example of the information which is displayed:

console#show version

Unit SW version Boot version HW version

------------------- ------------------- ------------------- ----------------

1 4.1.0.20 1.0.0.14 00.00.02

2 4.1.0.20 1.0.0.14 00.00.02

3 4.1.0.20 1.0.0.14 00.00.02

 

Hope this helps
