3.2.5Wall-Mounting the STH

When an STH is installed on a wall, its cable connections must face down to prevent the sideways stresses of hanging cables from compromising the connection at the port.

Note: 1/4-inch anchors for wall mounting are not included with the STH-ACCY-KIT package.

1.Use the supplied screws to attach the wall mounting brackets to the bottom of the STH as shown in Figure 3-5. There are two brackets, one for each side.
