3500电源模块是半高模块，必须安装在框架zui左边特别设计的插槽内。3500框架可以安装一个或两个以任意形式组合的交流或直流电源模块:每个电源模

块都能单独为整个框架供电。如果安装了两个电源模块，那么它们一主一备。只要安装了备用电源模块，插拔主电源模块将不会对框架的运行造成中断。

3500电源模块接受宽范围输入电压，并将它们转换成3500模块可接受的工作电压。

3500/15交流与直流电源操作与维护手册

3500交流电源模块有两种型号电源输入模块(PIM)，可接受两种范围的交流

输入电压:高压交流PIM接受175到264Vacrms:低压交流PIM 接受85到132 Vac rms。

高压直流电源模块支持88到140Vdc直流输入:低压直流电源模块支持20到30Vdc直流输入。

2.2单一电源模块

3500在仅有一个供电电源时亦能满载运行。如果只安装一个供电电源模块，我们建议安装在电源模块插槽的上半部。

2.3冗余电源模块

当安装2个供电电源时，下半部插槽内的电源模块为主电源，上半部插槽为备

用电源。如果主电源故障备用电源在不中断框架运行的情况下继续为框架供

电。

每个电源模块在各自独立的配电网络上供电，这就确保了一个配电网络的故障

(比如+5伏电源短路)将不会对另一个供电电源造成影响。

The 3500 power module is a half-height module that must be installed in a specially designed slot on the far left side of the frame. The 3500 frame can be mounted with one or two AC or DC power modules in any combination: each power module

Each block can individually power the entire frame. If two power modules are installed, one is active and the other is standby. If a standby power module is installed, the active power module can be removed without interruption.

The 3500 power supply module accepts a wide range of input voltages and converts them into an acceptable operating voltage for the 3500 module.

3500/15 AC and DC Power Supply Operation and Maintenance Manual

3500 AC Power module The AC power input module (PIM) supports two types of AC

Input voltage: High voltage AC PIM accepts 175 to 264Vacrms: Low voltage AC PIM accepts 85 to 132 Vacrms.

The high voltage DC power module supports 88 to 140Vdc DC input. The low voltage DC power module supports 20 to 30Vdc DC input.

2.2 Single Power Module

The 3500 can also operate at full capacity with only one power supply. If only one power module is installed, it is recommended to install it in the upper half of the power module slot.

2.3 Redundant Power Modules

When two power supplies are installed, the power module in the lower slot is the active power supply, and the upper slot is the standby power supply

Use the power supply. If the main power supply fails, the standby power supply continues to supply the frame without interrupting the frame operation

Electricity.

Each power module supplies power on its own distribution network, which ensures a distribution network failure

(such as a +5 volt power supply short circuit) will not affect the other power supply.
