BEFORE YOU BEGIN

Before setting up the software for a replacement Cisco Nexus 1010, you must know or do the following:


Step 1 Collect the following information from the functioning Nexus 1010.

Software version

HA role

The HA role of the functioning Cisco Nexus 1010 determines the role assigned to the replacement Cisco Nexus 1010.

If the functioning Cisco Nexus 1010 is in the primary HA role, the software for the replacement Cisco Nexus 1010 must be set up in the secondary HA role.

If the functioning Cisco Nexus 1010 is in the secondary HA role, the software for the replacement Cisco Nexus 1010 must be set up in the primary HA role.

Control VLAN

Management VLAN

Domain ID

Network uplink type

When setting up the software for the replacement Cisco Nexus 1010, you must use the same IDs used on the functioning Cisco Nexus 1010.

Step 2 Prepare the replacement Nexus1010 by doing the following:

a. Perform a total firmware update. See CIMC And BIOS Information

Verify the firmware ISO image.

b. Install the same software version on the replacement Nexus 1010 as that on the existing Nexus 1010.

The software versions running on the functioning Cisco Nexus 1010 and the replacement Cisco Nexus 1010 must match. The replacement Cisco Nexus 1010 has the latest software version installed on it when it is shipped.
