Note For information about powering down, disconnecting, repacking, and shipping the Cisco Nexus 1010, refer to the Cisco Nexus 1010 Virtual Services Appliance Hardware Installation Guide.
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.
–If you need to downgrade the software version on the replacement Cisco Nexus 1010, use the procedure in the Information About Reinstalling the Software.
–If you need to upgrade the software on one of the Cisco Nexus 1010s, use the procedure in the Upgrading from Software Release 4.2(1)SP1(2) or Later.
Step 3 Connect the replacement Nexus1010 to the upstream switch. See the Cisco Nexus 1010 Virtual Services Appliance Hardware Installation Guide for information about connecting to upstream switches.
Step 4 On the existing Nexus1010 Virtual Supervisor Module (VSM), do the following:
•Get the following information:
–VSM version
–Domain ID
–Management IP address
–IP subnet mask
–Gateway IP address
•Check that the corresponding ISO image is present. If it is not present, bring it in.
