Extreme Networks 220-12t-10GE2 电源模块说明

一、总体概述

Extreme Networks 220-12t-10GE2 属于 220 系列交换机，该系列定位于中小企业和分支机构的高性能接入层网络设备。
在电源方面，这款交换机采用 内置固定式 AC 电源，默认配置中不支持用户自行更换的热插拔电源模块。

二、电源类型与配置

• 电源类型：内置固定 AC 电源（非模块化）

• 输入电压范围：100V～240V AC，50/60Hz

• 额定功耗：最大约 200W（含 PoE 输出）

• PoE 供电能力：总功率预算约 185W（支持 IEEE 802.3af/at 标准）

• 冷却方式：内置智能风扇调速，自动根据温度调节转速

三、冗余电源支持

虽然 220-12t-10GE2 的主电源为固定式，但该系列支持外接冗余电源（RPS），用于在主电源故障时提供备用供电。
常见可配套使用的冗余电源型号为 RPS-150XT，该装置为外部电源单元，可通过专用电缆连接到交换机上，实现冗余保护。

冗余电源特性：

• 输出功率：约 150W

• 接口类型：专用 RPS 连接口

• 电源输入：100–240V AC

• 功能：在主电源失效时自动接管供电，保障网络设备连续运行

四、常见电源相关问题与建议

1. 是否能更换电源模块？
   不支持热插拔或独立更换电源模块，内部电源损坏时通常需整机维修或返厂更换。

2. 是否需要外接冗余电源？
   如果设备用于关键业务（例如核心监控、主办公网络），建议选配外部 RPS 设备，提高可靠性。

3. 电源功率是否足够？
   当所有 PoE 端口同时为高功率设备供电时，应注意 185W 的 PoE 总功率上限，避免超负载。

4. 工作环境要求
   建议放置于通风良好处，确保风扇通道畅通，以防过热导致电源降功率或保护。

Extreme Networks  220-12t-10GE2电源模块 英文介绍

Extreme Networks 220-12t-10GE2 Power Module Description

1、 Overall Overview

Extreme Networks 220-12t-10GE2 belongs to the 220 series switches, which are positioned as high-performance access layer network equipment for small and medium-sized enterprises and branch offices.

In terms of power supply, this switch adopts a built-in fixed AC power supply and does not support user replaceable hot swappable power modules in the default configuration.

2、 Power type and configuration

Power type: Built in fixed AC power supply (non modular)

Input voltage range: 100V~240V AC, 50/60Hz

Rated power consumption: up to approximately 200W (including PoE output)

PoE power supply capability: total power budget of approximately 185W (supporting IEEE 802.3af/at standard)

Cooling method: Built in intelligent fan speed regulation, automatically adjusts the speed according to temperature

3、 Redundant power supply support

Although the main power supply of 220-12t-10GE2 is fixed, this series supports external redundant power supply (RPS) to provide backup power in case of main power failure.

The commonly used redundant power supply model is RPS-150XT, which is an external power unit that can be connected to a switch through a dedicated cable to achieve redundant protection.

Redundant power supply characteristics:

Output power: approximately 150W

Interface type: Dedicated RPS connection port

Power input: 100-240V AC

Function: Automatically take over power supply in case of main power failure, ensuring continuous operation of network equipment

4、 Common power related issues and suggestions

Can the power module be replaced?

It does not support hot swapping or independent replacement of power modules. When the internal power supply is damaged, it usually needs to be repaired or returned to the factory for replacement.

Do we need an external redundant power supply?

If the equipment is used for critical business (such as core monitoring, main office network), it is recommended to choose external RPS equipment to improve reliability.

Is the power supply sufficient?

When all PoE ports are supplying power to high-power devices simultaneously, attention should be paid to the maximum total PoE power of 185W to avoid overloading.

Work environment requirements

It is recommended to place it in a well ventilated area to ensure that the fan channel is unobstructed, in order to prevent overheating from causing power reduction or protection.
