Console Switch/Server Symbol?

Hello all,

I am making a bunch of diagrams for some networks I'm turning over to another company and for the life of me I cannot think of what symbol to use for remote console access devices. The diagrams are supposed to be topology diagrams rather than technologies, so they will use generic switch and router icons, etc., but I need to portray a console server for out-of-band access like a Raritan or WTI device. If anyone has any ideas, it would really help me out.

Thanks so much!
