Installing the Cable Guide (Optional)
One cable guide is provided in the accessory kit. The cable guide attaches to the rack-mount bracket
using a single M4 screw (a threaded M4 hole is provided in the rack-mount bracket). The cable guide is
designed to be used when the rack-mount brackets are attached to the front of the chassis and can be
attached to either the left side or the right side of the chassis.
Note If the chassis is mounted to the rear posts of the equipment rack, the cable guide cannot be installed.
