switch-5-1 is a Netgear 10Gbe managed switch. The model is ProSafe XS716T. This switch is unlike many of the other switches in that you cannot ssh/telnet into it. You must tunnel into the private network and access it via it's IP address: 10.20.109.33.
Currently, the switch only has a single gigabit link between it and switch-4-1. I hope to purchase some GBICs/SFPs and then link it with RACK0.
Quick Starting a fresh NetGear switch
By default, the XS716T will have a starting IP address of 192.168.0.239 and a subnet mask of 255.255.255.0. I connected to this switch by changing my local Windows 10 laptop's network adapter IP Address to 192.168.0.240 and my subnet to 255.255.255.0. This allows my laptop to be in the same LAN as the network switch. Then I downloaded Netgear's Smart Control Center: https://www.netgear.com/support/product/Smart%20Control%20Center%20(SCC).aspx#download
Once I connected to any port on the switch via ethernet cable to my laptop, I was able to access the switch's configuration page with a web browser by putting the switch's default IP address 192.168.0.239 into the URL entry. From here, I was able to assign the proper static configurations.
