The PoE classes are programmed into the chips of the devices, so this cannot be modified by a firmware upgrade. GS105PE can be powered by either IEEE 802.3af or IEEE 802.3at from either a PoE switch or a PoE injector. Prioritize voice/video With the ability to set up and configure QoS, this Gigabit Plus switch can detect different types of network traffic and assign the desired priority to latency-sensitive traffic, such as voice and video. This helps improve the delivery quality of related applications such as VoIP, multimedia broadcasting, and video conferencing. The GS105PE is a PoE passthrough switch which can only be powered by Power Over Ethernet (does not accept AC power).
GS105PE supports loop detection. When a loop is detected, the Link/Act and Speed LEDs on the affected port will blink at a constant speed with roughly 1 every second. Insert a straightened paper clip or a similar device into the hole of the Factory Default button and hold for two to three seconds.On top of the Plug-n-Play Gigabit Ethernet connectivity, this NETGEAR GS105PE switch also offer essential networking features such as two (2) PoE ports, VLAN, QoS, IGMP Snooping, Link Aggregation (LAG), rate limiting and traffic monitoring. By listening in on the IGMP conversation between hosts and routers, the NETGEAR GS105PE ProSafe Plus switch can maintain a map as to which links need which IP multicast streams. The NETGEAR GS105PE ProSafe Plus switch therefore will be able to forward multicast traffic only to the links that have asked for them and cut multicast traffic from links that do not contain a multicast listener. Essentially, IGMP snooping helps optimise multicast performance at Layer 2 and is especially useful for bandwidth-intensive IP multicast applications such as IPTV. Even if the WN203 has a power consumption corresponding to a class 2, it is a class 0 device, so it cannot be powered on when the GS105PE is powered by an 802.3af switch or injector. PoE pass through is getting power from PSE (Power Source Equipment) (eg. GS752TP, the PoE Smart Switch) and provides surplus power to other PoE PDs (Powered Devices). Note on 802.3at interop issues with certain Cisco switches: Interop problems have been identified when the GS105PE is powered by some Cisco PoE+ switches. Certain Cisco switches (such as the 3560CG-8-PD) are pre-standard 802.3at and do not fully meet the 802.3at standard. Other Cisco switches (such as the Catalyst 2960S) have also been found to be not fully compatible and Cisco has a bug open for this.
The switch isn’t a standalone device: it can be powered only by connecting its fifth port to a PoE switch or power injector. The idea is that the GS105PE extends the PoE capabilities of the main switch to those places in the office it can’t reach. The switch provides PoE passthrough services on ports 1 and 2, but it prioritises port 1, so it will shut power to port 2 if consumption reaches the maximum power budget.
NetGear GS105PE-10000S ProSAFE 5-Port POE/PD Gigabit Plus Switch
Netgear’s new ProSafe Plus switches offer plug-and-play simplicity to small businesses, plus PoE expansion and handy traffic-management features. The GS105PE is the smallest of the family and provides five Gigabit ports. Port mirroring lets you send data from selected ports to others for network monitoring, as well as run basic cable tests and flag up faults. The switch can manage up to five port-based VLANs and apply one of five QoS priorities to each port for prioritising data such as voice and video. Added a control option to disable or enable file transfer via TFTP (Trivial File Transfer Protocol), under System > Management > Switch Managed Mode). Default is Disable. Take care powering the switch, since the input source determines its power budget and the device class it can support. Our HP ProCurve 2626-PWR switch supplies 802.3af PoE, which limits the budget to 8W and Class 1 and 2 devices. This meant we could power a small Axis 216FD camera, but didn’t have enough juice for our D-Link business wireless APs or Axis Q1755 Class 3 IP camera. Connecting the GS105PE to a TP-Link TL-SG3424P 802.3at PoE+ switch increased the budget to 20W and support for Class 0 and 3 devices, but there was still only enough power for one of those devices.
The NETGEAR GS105PE ProSafe Plus 5-Port Desktop Gigabit PoE Switch meets the growing needs of small businesses by providing fundamental network features that will help optimise the performance their networks. This is a 5-port Gigabit switch with PoE Pass Through. It belongs to NETGEAR’s 2nd generation of ProSAFE Plus Switch.
Many PoE devices don’t have any specific class defined, and these devices are generally classified as a class 0 device. Yes, when it is powered by 802.3af switch, it can supply power to class 1 or 2 PD only. When it is powered by 802.3at switch, it can supply power to class 0, 1, 2 or 3 PD. Please refer to the detailed information on the installation guide. There is a configuration utility in the resource CD that comes with the device. You must install it on a window-based PC. Will there be any behavior difference when it is powered by an IEEE802.3 af or an IEEE803.at PoE switch? Be careful not to mix it up with the Reset button. The Reset button restarts the switch, it does not restore it to factory default settings.
