You may remove and insert switching modules while the switch is running. This technique is 
referred to as “hot swapping.” When you hot swap, you must replace the module with the 
same module type as the one you removed. For example, if you remove an 

ESX

 switching 

module you must replace it with another 

ESX

 switching module.

♦ Note ♦

You cannot hot swap a module into a previously 
empty slot. To use an empty slot, you must power 
down your chassis.

Perform the following steps to safely hot swap a switching module. (You cannot hot swap a 
primary 

MPX

 module.) Since this procedure could possibly disrupt the network, it is best to 

hot swap during network down times.

1. At the system prompt, enter

where 

 is the number of minutes you want the switch to be in swap mode (the 

default is 5 minutes). A message similar to the following will be displayed.

The swap mode must be enabled (

) to insert a switching module. If not, the system 

may halt or restart. (See Chapter 6, “Configuring Management Processor Modules,” for 
more information on the 

 command.)

♦ Caution ♦

Modules can only be reset and hot-swapped when the 

MPX’s

 

 light is in its normal flashing green state.

2. Enter 

, followed by the slot number of the switching module you want to hot swap, 

then followed by the word 

. (See Chapter 36, “Running Hardware Diagnostics,” for 

more information on the 

 command.) For example, if you want to hot swap the 

switching module in slot 4, you would enter

at the system prompt. Next, the switch will prompt you to confirm the reset. The follow-
ing is an example of the display for an 

ESX

 module. The display for other types of switch-

ing modules will be similar.

Press 

 and then press 

. If the switching module is in slot 4, a message similar to 

the following will be displayed.

3. The 

MPX’s

 

 

LED

 will flash amber 1 or 2 times, then return to normal flashing green. 

The switching module’s 

 

LED

 will turn amber and the 

 

LED

 will not be illumi-

nated. Remove all cables attached to ports on the switching module that you are going to 
swap out.
