1. A computing node, comprising:
a host central processing unit;
at least one storage device for storing program instructions; and
a service processor that is not the host central processing unit, the service processor configured to process the program instructions to:
send an out-of-band request for access to an operator panel, wherein the out-of-band request is sent over a local network domain operatively coupling the service processor to service processors of a plurality of computing nodes, and wherein at least one of the computing nodes has a connected operator panel;
receive a first out-of-band reply identifying an address and one or more capabilities of the connected operator panel accessible over the local network domain, wherein the first out-of-band reply is received from the service processor of the computing node having the connected operator panel; and
negotiate an active link to the connected operator panel over the local network domain.
