Rear Panel - Planet GSD-908HP User Manual

2.2 Rear Panel

The rear panel of the PoE Ethernet Switch indicates a DC power socket, which
accepts DC 51V input power; there is a security slot that allows using an anti-
theft lock to attach the PoE Ethernet Switch to a fixed object against theft. The
grounding terminal provides lightning protection ability for the PoE Ethernet Switch.
The device is a power-required device, meaning it will not work till
it is powered. If your networks should be active all the time, please
consider using UPS (Uninterrupted Power Supply) for your device.
It will prevent you from network data loss or network downtime.

In some areas, installing a surge suppression device may also help
Notice
to protect your GSD-908HP from being damaged by unregulated
surge or current to the GSD-908HP or the power adapter.
Before startup
Before your installation begins, please refer to the following for your cabling:
10/100/1000Base-T (Port 1 to Port 9)
The 10/100/1000Base-T port comes with Auto-Negotiation capability, which
automatically supports 1000Base-T, 100Base-TX and 10Base-T networks. Users
only need to plug a working network device into the 10/100/1000Base-T port, and
then turn on the PoE Ethernet Switch. The port will automatically run in 10Mbps,
20Mbps, 100Mbps or 200Mbps and 1000Mbps or 2000Mbps after negotiating with
the connected device.
Cabling
Each 10/100/1000Base-T port uses RJ-45 sockets -- similar to phone jacks
-- for connection of unshielded twisted-pair cable (UTP). The IEEE 802.3 /
802.3u / 802.3ab Fast / Gigabit Ethernet standard requires Category 5 UTP for
100Mbps 100Base-TX. 10Base-T networks can use Cat.3, 4, 5 or 1000Base-T uses
Cat.5/5e/6 UTP (see table below). Maximum distance is 100 meters (328 feet).

Any Ethernet devices like hubs/PCs can connect to the GSD-908HP PoE Ethernet
Switch by using straight-through wires. The nine RJ-45 ports are auto-MDI/MDI-X,
which can be used on straight-through or crossover cable.
