This server supports one rail kit option: Cisco part UCSC-RAILB-M4= (ball-bearing rail kit).
Do not attempt to use a rail kit that was for the Cisco UCS C240 M3 server;
the rail kit for the Cisco UCS C240 M4 server has been designed specifically for it.
Serial Number Location
The serial number (SN) for the server is printed on a label on the top of the server, near the front.
Hot-Swap or Hot-Plug Replacement
Some components can be removed and replaced without powering off and removing AC power from the server.
• Hot-swap replacement—You do not have to precondition or shut down the component in the software before you remove it for the following components:
– SAS/SATA drives
– Cooling fan modules
– Power supplies (when 1+1 redundant)
Controllers for Internal Drives
Note that if the following Cisco 12G SAS Modular RAID controller or Cisco 12Gbps Modular SAS HBA controller is selected, it is factory-installed in the dedicated internal slot.
