Replacement procedure overview
This section highlights the requirements and considerations when replacing
nodes.
Requirements
Any personnel attempting the following procedures must have completed the
necessary training before proceeding. Much of the process required for a
server replacement is the same process covered in installation and
configuration training. No personnel should attempt to replace a unit without
adequate training and authorization.
Determine which replacement scenario is being encountered in advance. The
replacement process is different for each scenario.
Acquire the temporary license keys before arriving onsite to expedite the
server replacement. The license keys are necessary because they are based
on the unique MAC ID for the server or cluster. New license keys are not
required when replacing one server in a cluster.
Note: Replacement servers are shipped without an embedded system
management unit (SMU), so you must have a SMU installed before you can
connect to a standalone server.
You can use a KVM (keyboard, video, and mouse) device or a serial cable to
connect to the serial port. Bring both devices with you just in case both are
needed when the unit arrives. If you connect to the serial port, use the
following SSH client settings:
• 115,200 b/s
• 8 data bits
• 1 stop bit
• No parity
• No flow control
• VT100 emulation
Swapping components
The server can be replaced onsite. However, some components are not
included in the replacement server that you receive. You must remove those
components from the original server and use them in the replacement server.
There are a minimum of four parts to be reused in the replacement server.
The components that can be swapped include:
• Battery
• Bezel
• Rack mounting guides
