The connected terminal device (not shown) and the network device 1 are electrically connected via the patch cord 34.

When the conventional network concentrator 41 as shown in FIG. 10 is installed inside the patch panel system 30, in order to make the status display section 15 of the apparatus main body 41 visible from the front, the apparatus main body 41 must be installed. A considerable space is required in the front-rear direction of the apparatus main body 41 including a space for connecting a cable to the cable 41. In addition, in order to reduce the space in the front-rear direction, the terminal connection port 14 is used.
When the apparatus main body 41 is installed so that the vertical direction or the horizontal direction is set, the status display unit 15 cannot be seen from the front.

However, in the network concentrator 1 shown in this embodiment, as described above, the terminal connection port 14 is provided on the lower surface of the network concentrator 1 in the normal installation state where the status display unit 15 can be checked from the front. Therefore, the patch cord 34 can be connected to the lower side of the patch panel system 30, and the AC input unit 16 and the backbone connection port 17 are provided on the side surface of the apparatus main body 1.
The AC power cord 22 and the backbone connection AUI cable 21 can be connected to the AC input unit 16 and the backbone connection port 17 on the left side of the apparatus main body 1 installed on the left side of the patch panel system 30, respectively. Therefore, the space for installing the network concentrator 1 and the wiring space for connecting cables can be reduced as compared with the conventional network concentrator 41. Also, the patch cord 34, the AC power cord 22, and the AUI cable 21
Can be easily separated from the apparatus main body 1.

In this embodiment, the terminal connection port 14
Is connected to the module plug 35 of the patch cord 34, but in a similar system, the terminal connection port 1 is connected.
Similar effects can be obtained even when the plug of the general twisted pair cable 20 is connected to the plug 4. In this embodiment, the AC input section 16 and the backbone connection port 17 are arranged on the left side of the apparatus main body 1. However, in a similar system in which the primary side patch panel 31 of the patch panel system 30 is on the right side. It is needless to say that the same effect can be obtained by disposing the AC input unit 16 and the backbone connection port 17 on the right side of the apparatus main body 1.
