I was recently remoting into my network and accessing my Precision R5500 computer. Some patch ran and forced a reboot and it hung on restart. Are there any hardware add-ons or other ways to remotely access the computer when it's not physically available? I have a KVM hooked up to it but not a network kvm. Thinking that's the only way but wasn't sure if Precision rack units had any kind of remote access card or something that can be plugged into the network to access at session 0.
