When you connect the C-Series servers in Cisco UCS system, make sure to review the following information:
The C-Series UCSM integration requires six 10-Gb SFP cables for the following purposes:
Caution |
Do not mix SFP types on an uplink. If you mix SFP types on an uplink, you will get Discovery failed errors. |
Cisco UCS C-Series server CIMC Release version 1.2(2) is the required level for integration with Cisco UCS Manager 1.4 or 2.0(1). If your server CIMC release version does not meet the requirement for integration with Cisco UCS Manager, make sure to upgrade the server firmware before connecting the server with Cisco UCS domain. For more information on upgrading the C-series server firmware, see the host upgrade utility quick start guide for your release http://www.cisco.com/en/US/products/ps10493/products_user_guide_list.html
After upgrading the server to the compatible server release version, you must establish the physical connection for the server to make it a part of Cisco UCS domain.To connect the server to your Cisco UCS FEXes and FIs, see Connecting the Server with Cisco UCS Domain.
Using the power button or Cisco UCS Manager, if you set the desired power status to Down for an integrated C-Series server's associated service profile, when you try to rest the server to the desired power state, the server becomes out of sync with the actual power state. This may cause the server to shut down unexpectedly at a later time.
Use the Boot Server action in Cisco UCS Manager to safely reboot a server from a power-down state.
The following table shows how the physical server power states can differ from the Cisco UCS Manager service profile power states when the power button on the server is used.
Initial Service Profile Power State |
Server Initial Power State |
Action From Physical Power Button |
Actual Server Power State After the Action |
Power State Under UCSM Equipment Tab |

Make sure to consider the following when using the adapter cards in Cisco UCS C-Series server integration with Cisco UCS Manager:
Whenever you decommission or recommission a Cisco UCS 2248 FEX, all the servers that are connected to that FEX must be re-acknowledged in UCS Manager.
