The AP is at chromeos3-row3-rack3-host19 location but I can only see up to host16 from chromeos3-row3-rack3-rpm1.

Ah yes, some RPMs are 16 ports, and some are 24 ports.
chromeos3-row3-rack3-host19 is the hostname but the physical location should be chromeos3-row3-rack4-host23.

chromeos3-row3-rack4-rpm1 shows up to host20.

Reassigning to dschimmels@ to pass onto donator@. After these bugs are completed, we can file bugs with Buganizer and assign directly to donator@.

You started fixing this bug over two years ago. Are you still working on it? You can update the status to "archived", "wontfix", or "closed". You can remove yourself as owner and change status to "untriaged", but if this is still a real bug, please do not sit on it.
