The dimensions of the Cisco ONS 15530 CHAS-N chassis are 14.4 x 15.7 x 10.1 inches (H x W x D).
(See Figure 1-5.) Handles for lifting the chassis are located on the top. The fan assembly draws in

over the internal components and out the exhaust on the top rear and sides of the chassis (see Figure 1-6).
