What are the main vendors of poe power supply switches?
The main brands of POE switches include H3C, Huawei (Quick), Cisco, D-Link, and others. Among these, Cisco, Huawei, and H3C are considered among the top three in the global market. If you're looking for a reliable and cost-effective option, many users find that H3C offers a better balance between quality and price.
**H3C POE Power Switch**
The H3C wireless POE injector is a product developed by H3C to support Power over Ethernet (POE) technology. It allows remote power delivery to connected devices such as IP phones and wireless access points, eliminating the need for separate power systems. This significantly reduces cabling and management costs when deploying terminal equipment. The H3C WP series supports a wide range of Ethernet protocols, offering more comprehensive access strategies, enhanced network management, and improved ease of use while ensuring efficient POE power output. It's an ideal choice for secure and user-friendly deployment.
**Huawei POE Power Switch**
Huawei’s low-end and mid-range switches typically come in 1U or 2U form factors without the need for port cards. These switches vary greatly in hardware versions and supported port types, so it's important to consider these differences when selecting switch devices for your network. Huawei’s naming convention for low-end switches is quite systematic, with parameters in the device name providing key information about its capabilities.
For example:
- **LI** stands for Lite software image, indicating a basic feature set.
- **SI** is Standard Image, containing essential features.
- **EI** is Enhanced Image, offering more advanced functions.
- **HI** is Hyper Image, featuring even more sophisticated capabilities.
When choosing a Layer 3 switch, it's crucial to check if the version supports dynamic routing protocols like OSPF. For instance, the S3328-SI and S3352-SI models do not support OSPF and only offer static routes and RIP. In such cases, the EI version would be required.
In terms of uplink ports, different letters indicate various interface types:
- **Z**: No uplink interface (not used in newer models).
- **G**: GBIC optical port.
- **P**: SFP optical port.
- **T**: RJ45 electrical port.
- **TP**: Combo port supporting multiple interfaces.
- **V**: VDSL uplink.
- **W**: Configurable WAN interface.
- **C**: Optional uplink.
- **M**: Multimode optical port.
- **S**: Single-mode optical port.
Port-related parameters include:
- **F**: Downlink template board, allowing for optical or electrical interface insertion.
- **PWR**: Indicates support for POE.
- **SXXYY**: Where XX represents the model number and YY the number of ports. For example, S3328 has 24 downlink ports + 4 uplinks, while S3352 has 48 downlink ports + 4 uplinks.
**Huawei S Series Switch Models**
Huawei Quidway S series switches are widely used in the market, with various models available:
1. **S9300 Series**: Includes S9303, S9306, and S9312. These switches have multiple service slots, with S9303 having 4 slots, S9306 having 8, and S9312 having 14.
2. **S8500 Series**: Models include S8502, S8505, S8508, and S8512. These switches provide main control redundancy and varying numbers of service card slots.
3. **S7800 Series**: Comprises S7802, S7803, S7806, S7810, and S7806V. These also feature dual main control boards and differ in the number of service interface slots.
4. **S5600 Series**: Available as 1U box-type switches, such as S5624 and S5648, with different port configurations and stacking capabilities.
5. **S5300 Series**: Includes S5328 and S5352, available in both electrical and optical port variants, with enhanced EI versions offering higher switching capacity.
6. **S3300 Series**: Comes in 1U form, with models like S3328 and S3352, supporting both electrical and optical ports.
7. **S2300 Series**: Offers SI and EI versions, with models like S2309TP-SI/EI and S2352TP-SI/EI.
