Supports IEEE802.3x flow control for Full Duplex mode and backpressure for Half Duplex mode
Supports MAC address auto-learning and auto-aging
LED indicators for monitoring power, link, activity
Plastic case, desktop or wall-mounting design
External Power Adapter supply
Chapter 2. Installation
2.1 Mounting the Switch on a Desk
To install the Switch, please follow the steps:
1) You can place the Switch on a flat desk.
