So do not look into the optical interfacedirectly.Cover the optical interface if there is no connector plugged in.Cable RoutingRecommendationsFreestanding Switch onTabletopFor only selling an integrated chassis, you do not have to care about the cablinginside or outside the cabinet. All the I/O module cables are routed from the leftside of the chassis (along the cabling channel), and the chassis power cords(AC/DC power cords) are routed in the front of the chassis.Cabinet-MountingSwitchIf the switch is mounted in a 19-inch standard cabinet or B68-22 cabinet, the I/Omodule cables are bound on the cabling rack at the left side of the chassis and arerouted up or down to pass through the chassis top or the raised floor dependingon the available equipment room condition (that is, the signal cables are routedinto the chassis either from the cabling rack on the chassis top or from the cablingtrough under the floor) of the exchange office. The power cords run along theleft-front of the chassis and out of the chassis either from the top or the raisedfloor depending on the equipment room conditions (DC power distributioncabinet, lightning protection box, and terminal block, etc.) of the exchange office.Cable ManagementCable ManagementRequirements■ Bundle and put the cables inside the cabinet in a straight and neat way. Nointertwinement or bending is allowed.
