Front panel
As shown in Fig.2, the front panel of the ZGWJ1(TY) network switch security protector has 50 RJ45 sockets. The lower row marks "1~25" as input ports, and the upper row marks "1~25" as output ports. “1” is a cascade port.
It is designed with a power indicator (green) and a degradation indicator (red).
Rear panel
As shown in Fig.3, the ZGWJ1 (TY) network switch security protector has two three-core power sockets on the rear panel. The socket with needle is the power input end including a power switch. Its input voltage is AC 220 V. The socket with hole is the power output end, connected to the protected network switch power supply. In addition there is a local grounding PE terminal.
