Standard, VLAN and Extend Operation Modes Offered
The GSD/GSW 802.3at PoE+ Switch series provides Standard, VLAN and Extend
operation modes. The GSD/GSW 802.3at PoE+ Switch series operates as a normal
IEEE 802.af/at PoE Switch in the Standard operation mode. The VLAN operation
mode features the port-based VLAN function that can help to prevent the IP
camera’s multicast or broadcast storm from inuencing each other.

In the Extend operation mode, the GSD/GSW 802.3at PoE+ Switch series operates
on a per-port basis at 10Mbps duplex operation but can support 30-watt PoE
power output over a distance of up to 250 meters overcoming the 100m limit on
Ethernet UTP cable. With this brand-new feature, the GSD/GSW Series provides
an additional solution for 802.3af/at PoE distance extension, thus saving the cost
of Ethernet cable installation. Its VLAN isolation function isolates ports so as to
prevent broadcast storm and defend DHCP spoong in the Extend operation mode.

Flexible Extension Solution
The two mini-GBIC slots built in the GSD/GSW 802.3at PoE+ Switch series are
compatible with the 1000BASE-SX/LX SFP (Small Form-factor Pluggable)
ber transceiver, uplinked to the backbone switch and monitoring center in long
distance. The distance can be extended from 550 meters (multi-mode ber) to
10/20/30/40/50/60/70/120 kilometers (single-mode ber or WDM ber). They are
well suited for applications within the enterprise data centers and distributions.
Robust Protection
The GSD/GSW 802.3at PoE+ Switch series provides contact discharge of ±6KV DC
and air discharge of ±8KV DC for Ethernet ESD protection. It also supports ±6KV
surge immunity to improve product stability and protects users’ networks from
devastating ESD attacks, making sure the ow of operation does not uctuate.
Easy Installation and Cable Connection
As data and power are transmitted over one cable, the GSD/GSW 802.3at PoE+
Switch series does not need a second cable and electrical outlets on the wall,
ceiling or any unreachable place. Thus, it helps to lower the installation costs and
simplify the installation effort. All the RJ45 copper interfaces of the GSD/GSW
802.3at PoE+ Switch series support 10/100/1000Mbps auto-negotiation for optimal
speed detection through RJ45 Category 6, 5 or 5e cable. It also supports standard
auto-MDI/MDI-X that can detect the type of connection to any Ethernet device
without requiring special straight-through or crossover cables.

The detailed Smart LCD description of each item is shown below:
Parameters Description
30.3W
(example) It means the output power port of the PoE switch.
OLP It means the port is overloaded corresponding to the PSE, and
the port stops powering.
ULP
It means the port corresponding to the PSE is lightly loaded
and the port stops powering (When the current on the network
is less than 7.5mA, the PSE thinks the PD has been dialed out
and the port stops powering).
SCP It means the port corresponding to the PSE appears to be
short-circuited and the port stops powering.
OFF It means the white and blue OFF shows that the port is blocked
by the menu command.
---W It means the port is without a PD device insert.
---M It means this port does not have data transfers.
<1M It means this port data rate transfers less than 1M.
877M
(example)
The white and blue character represents the data transmission
rate while the red character represents the data transmission
rate which is greater than the bandwidth setting, causing power
to restart the PSE port. If the resumption situation happens for
10 times within 1 hour, the power supply to the port will be cut
off.
PB It means power budget.
TB It means total PoE power output information.
PD The number of PDs inserted.

Figure 2-5: GSW-1820VHP/GSW-2620VHP Switch Rear Panel
AC Power Receptacle
For compatibility with electrical outlet standard in most areas of the world, the
802.3at PoE+ Switch’s power supply automatically adjusts to line power in the
range of 100-240V AC and 50/60Hz, 2.5/5A.
Plug the female end of the power cord rmly into the receptacle on the rear panel
of the 802.3at PoE+ Switch and the other end into an electrical outlet, and the
power will be ready.

Notice
The device is a power-required device, which means 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 to protect your 802.3at PoE+ Switch from being
damaged by unregulated surge or current to the Switch or the
power adapter.
