In this embodiment, the storage unit 2
Each of the communication devices 23 housed in the storage unit 5 has two electrical connection portions 23a and two optical connection portions 23b alternately in the upper and lower directions, and two electric cable support members 41 are arranged on each of the left and right sides of each storage unit. Have been. As shown in FIG. 3, a protruding portion 41 a protruding toward the optical cable introduction path 35 is formed on the rear surface 21 a side of the electric cable support member 41.

In this embodiment, the convection guide plate 43 is disposed in the slant processing unit 29 in an inclined state, and the convection guide plate 43 transfers heat generated from the lower communication device 23 to the outside. I try to guide. In the above-described cable introduction structure of the device rack for communication equipment, as shown in FIGS. 1 and 2, the optical cable 27 is introduced from below the device frame main body 21 along the optical cable introduction path 35.
