I have the switch in ienem 19 "rack installed. Angle to be at, cage nuts / bolts are not. The device is fanless and operates virtually silently. I have multiple NAS servers and application servers connected to it. Performance is as expected impeccable. The switch also features a GUI - you have one with a fixed IP (at the NIC) to access the address 192.168.0.1. then you can put the IP address to a different value. Just as one can also specify a time server and can make various Einstellugnen (VLAN, LAG, ..).
