Upgrade to a 4-Port 10 GE Module

Language:

The 4-Port 10 GE module can be swapped into a slot that previously contained another type of Ethernet I/O Module. Even though the module will install mechanically in the slot due to all I/O Modules having the same dimensions, the software is not guaranteed to preserve the correct number and configuration of vNICs from the previous module to the 4-Port 10 GE module. For example, if you remove a 1-Port 10 GE module (1x10) and insert a 4-Port 10 GE module, there is no guarantee that the previous configuration from the 1-Port 10 GE module (10x1) will be available when the 4-Port 10 GE module boots up.

As a result, if you will be using a 4-Port 10 GE module, you can either install it in a slot that previously had no other module in it, or you can install it in a module that previously had a GE module. The following procedure documents how to upgrade a previous 10-Port, 1 GE module to the 4-Port 10 GE module. For illustrative purposes, the procedure assumes that a module exists in slot 4, and the 4x10 module will be inserted into that slot. However, the 4-Port GE module does not always need to be inserted in the same slot. You can install it in a different slot if needed.

Note - While performing any hardware procedures, including swapping or upgrading a module, make sure to observe proper ESD precautions.

To upgrade to a 4-Port 10 GE Module follow this procedure:

With the previous module installed, set each physical interface supporting a vNIC to none. For example:

set vnic <vnic-name> -if=none
set vnic <vnic-name> -if=none
set vnic <vnic-name> -if=none
set vnic <vnic-name> -if=none

When all vNIC interfaces are set to none, turn off the I/O Module. For example:
```
set ethernet-card 4 down
```

Disconnect cables from the 10-Port 1 GE module.

Issue the remove iocard command.
```
remove iocard 4
```

When the command completes, physically remove the previous Ethernet card.

Install the 4-Port 10 GE I/O card.

Wait for the I/O card to power up.

Insert cables.

Set the vNICs back to the port(s) where you want them terminated. For example, if you want one vNIC terminated on each port:
```
set vnic <vnic-name> -if=4/1
set vnic <vnic-name> -if=4/2
set vnic <vnic-name> -if=4/3
set vnic <vnic-name> -if=4/4
```
Note - You do not need to terminate one vNIC on each port. You can re-terminate the vNICs as needed on any port. Terminating one vNIC on each port was chosen only for illustrative purposes in this example.

As an alternative, if you are installing the 10-Port GE module into a different slot (for example, slot 5) you can re-terminate the vNICs from the old 10-Port 1 GE module on that new slot. For example:
```
set vnic <vnic-name> -if=5/1
set vnic <vnic-name> -if=5/2
set vnic <vnic-name> -if=5/3
set vnic <vnic-name> -if=5/4
```
