CISCO 3750X stacking for 5 switches , only 4 switches are coming in stack

[nabil.shaikh]

Dear All,

I have 5 cisco 3750X switches ,but only 4 switches coming up 5 switches i am unable to see .

Connection for the switch :Please find the attached snapshot for the stack data connection .

Also find the snapshot for the stack power connection .

Please provide your assistance and support to overcome this issue .

Data from stack_data_connection.jpg & stack_power_connection.jpg are useless.

show_switch_snapshot.jpg is showing the stack were all powered up simultaneously.  Have you tried checking the power for switch stack #5? 

[Marvin Rhoads]

The 3750-X models have a data stack and power stack. The power stack is limited to four switches, so a fifth one would have to be in a separate power stack.

You can form a data stack however with up to 9 members. When you plug into console on switch #5, what does it show for "show switch detail".

All other 4 switches i can see in stack but not these switches and also the status light for this switches is blinking green  please provide your assistance .

[Marvin Rhoads]

Your switch is not booting IOS and is is the pre-boot condition known as "rommon". (Read Only Memory MONitor)

This is usually due to a deleted or corrupted IOS image. You need to recover the image and boot the IOS fully for the switch to be able to join the data stack. Here is a reference to the commands available to you in rommon mode.

Use dir to figure out what you have and then copy to move the files into flash (if necessary). Then boot using the restored image.
