Detecting a type of storage adapter connected and miscabling of a microbay housing the storage adapter

A computer system, comprising:

• one or more processors, one or more computer-readable memories and one or more computer-readable, tangible storage devices;
• and
• program instructions, stored on at least one of the one or more computer-readable, tangible storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, to perform operations comprising:
• under control of an Input/Output (I/O) bay,
• driving cable sidebands of a cable high for a first predetermined period of time;
• waiting for a second predetermined period of time;
• determining whether a cable sidebands response has been detected that indicates that the cable sidebands have been driven low;
• in response to determining that the cable sidebands response has been detected that indicates that the cable sidebands have been driven low,
• determining that the I/O bay is connected to a first storage adapter housed in a microbay;
• and
• communicating, through the cable, with the first storage adapter using a first protocol for the cable sidebands;
• and
• in response to determining that the cable sidebands response has not been detected,
• determining that the I/O bay is connected to a second storage adapter;
• and
• communicating, through the cable, with the second storage adapter using a second protocol for the cable sidebands.
