Arris SB6190 and TL-SG108 Rack Mount - Fan cooled (STEP)

thingiverse

This is a 19 inch rack mount for an Arris SB6190 SurfBoard cable modem. It has an integrated fan with a regulated power supply. A nifty Blue LED lights up the fan from the rear. The Rack mount is divided into 2 halves. One half has the modem mount, fan, power supply, and a single keystone mount. The other half is for mounting a: TP-Link TL-SG108 using the rack mount here: https://www.thingiverse.com/thing:3690500 or a Netgear NG-GS308 using the rack mount here: https://www.thingiverse.com/thing:3758303 It can also be used with the blank section here: https://www.thingiverse.com/thing:4410826 Four versions are supplied. Version one has a keystone mount integrated with the modem mount. The other half is for the TP-Link or Netgear switch Version two is a slightly shortened modem mount without a keystone mount. The other half is for the TP-Link or Netgear switch. This version is intended for smaller printers and requires a bed no larger than 220mm x 220mm. Versons three and four are similar to above but have a blank panel on the left instead of the switch mount. It is just like my Arris SB6190 Rack Mount https://www.thingiverse.com/thing:4385766 except the mounting ears are configured for the switches mentioned above. The fan is rated at about 30 dba. While fairly quiet I wouldn't want it in the bedroom. Like most fans this one is rated for 4.5-13.8 VDC. Many wall-wart type power supplies output 16+ volts unloaded which can let the magic smoke out so I added a small switching regulator from Pololu. The power connector is a 5.5mm × 2.1mm plug which is not the same size used on the SB6190 modem. If a regulated wall-wart is used then use the unregulated version of the power supply board assembly. March 9, 2021 - Versions with the modem mounted on the left side are now available.
