Freestanding Switch on
Tabletop
For only selling an integrated chassis, you do not have to care about the cabling
inside or outside the cabinet. All the I/O module cables are routed from the left
side of the chassis (along the cabling channel), and the chassis power cords
(AC/DC power cords) are routed in the front of the chassis.

side 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-Mounting
Switch
If the switch is mounted in a 19-inch standard cabinet or B68-22 cabinet, the I/O
module cables are bound on the cabling rack at the left side of the chassis and are
routed up or down to pass through the chassis top or the raised floor depending
on the available equipment room condition (that is, the signal cables are routed
into the chassis either from the cabling rack on the chassis top or from the cabling
trough under the floor) of the exchange office. The power cords run along the
left-front of the chassis and out of the chassis either from the top or the raised
floor depending on the equipment room conditions (DC power distribution
cabinet, lightning protection box, and terminal block, etc.) of the exchange office.
