I was able to connect to the router (the one on top of the switch in the rack next to the orange tool drawers) and reconfigure it using the same internal IP as found labeled and mentioned in . The router now has a different external IP that I wrote on the router (twice). The network/router and switch is now working in the lab.
Update: It turns out that the router reset itself somehow. so any settings/ port forwarding that was set up before has probably been wiped out and would need to be set up again.
SSHing into the QIL needs to be set up again.
