Power Supply Modules Overview

The switch operates with either one or two active power supply modules. A switch that is part of a StackPower

stack operates with power that is supplied by other stack switches.

You can use two AC modules or one module and blank cover. All power supply modules have internal fans.

All switches ship with a blank cover in the second power supply slot.

The following table describes the supported internal power supply modules. It lists the Platinum certified

power supply modules and the default modules that are shipped with the switch. In a switch, a mix of Platinum

certified and non-Platinum certified power supply modules is supported.

Installing a Power Supply

1. PWR-C1-1900WAC-P provides 1900 W output power when the nominal input voltage is 230 V. If the

nominal input voltage is 115 V, then the output power is limited to 1500 W. See Table 2 for suitable power

cord options.

For more information about power supplies, see Specifications for the Power Supplies, Switches, and

Fan.

Note

For information on available PoE, PoE+, and Cisco UPOE/UPOE+ requirements, see these sections the Power

Supply Modules.

The 350 W and 715 W AC power supply modules are autoranging units that support input voltages from 100

through 240 VAC. The 1100W power supply module is an autoranging unit that supports input voltages from

115 through 240 VAC.

Each AC power supply module has a power cord for connection to an AC power outlet. To view the list of

available AC power cords, see AC Power Cord Specifications.

The following illustrations show the power supply modules.

Installation Guidelines

Observe these guidelines when removing or installing a power supply or fan module:

• Do not force the power supply or fan module into the slot. This can damage the pins on the switch if they

are not aligned with the module.

• A power supply that is only partially connected to the switch can disrupt the system operation.

• Remove power from the power-supply module before removing or installing the module.

• The power supply is hot-swappable. In some configurations, such as full PoE+ or power sharing mode,

removing a power supply causes powered devices to shut down until the power budget matches the input

power of a single power supply. To minimize network interruption, hot swap the power supply under

these circumstances:

• The switch is in StackPower mode and sufficient power is available.

• The switch is powered by other switches in a power stack, and no active backup is in progress.

For the switch commands that display available power budget, see the software configuration guide.

Installing a Power Supply

Installation Guidelines

Do not operate the switch with one power-supply module slot empty. For proper chassis cooling, both module

slots must be populated, with either a power supply or a blank module.

Caution

This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence

of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician

if you are uncertain that suitable grounding is available.

Statement 1024

Warning

Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages

and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other

equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all

cards, faceplates, front covers, and rear covers are in place.

Statement 1029

Warning

Do not reach into a vacant slot or chassis while you install or remove a module. Exposed circuitry could

constitute an energy hazard.

Statement 206

Warning

Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

Statement 1030

Warning

If a Cisco external power system is not connected to the switch, install the provided connector cover on the

back of the switch.

Note

Equipment That You Need

• Ratcheting torque screwdriver with a number-2 Phillips head that exerts up to 15 pound-force inches

(lbf-in.) of pressure.

• Panduit crimping tool with optional controlled-cycle mechanism (model CT-720, CT-920, CT-920CH,

CT-930, or CT-940CH).

• Wire-stripping tools.

• 12-gauge copper ground wire (insulated or not) for the single-hole ground connection.

• 8-gauge copper ground wire (insulated or not) for the dual-hole ground connection.

• Dual-hole ground lug and two screws (included in the DC power supply accessory kit) and single-hole

ground lug and screw (included in the switch accessory kit). The dual-hole lug is required for the grounding

of the switch in NEBS installations where the DC supply is the only NEBS compliant power supply

option.

• Four leads of 14-gauge copper wire.

Installing a Power Supply

Installing a DC Power Supply

• Four fork-type terminals from the DC power supply accessory kit. The terminals must be the proper size

for M3 screws in a Dinkle DT-35-B25-style terminal block.

• M5 screws for 12 AWG wire connection for NEBS installations.

Grounding the Switch

Follow these steps to install either a single-hole ground lug or a dual-hole ground lug on the switch. Make

sure to follow any grounding requirements at your site.

Before you begin

Follow the grounding procedures at your site and observe these warnings:

This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence

of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician

if you are uncertain that suitable grounding is available. Statement 1024

Warning

When installing or replacing the unit, the ground connection must always be made first and disconnected last.

Statement 1046

Warning

Follow the grounding procedure instructions, and use a UL-listed lug (included in the accessory kit).

Caution

To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect

the (Management Ethernet) ports only to intra-building or unexposed wiring or cable. The intrabuilding cable

must be shielded and the shield must be grounded at both ends. The intra-building port(s) of the equipment

or subassembly must not be metallically connected to interfaces that connect to the OSP or its wiring. These

interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in

GR-1089-CORE) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is

not sufficient protection in order to connect these interfaces metallically to OSP wiring.

Caution

Procedure

Step 1 Use the ground lug screw and the lug ring for single-ground connections. Use the dual-hole lug for ground

connections for NEBS installation.

Step 2 Strip the 12-gauge or 8-gauge ground wire to 0.5 inch (12.7 mm) ± 0.02 inch (0.5 mm). Stripping more than

the recommended amount of wire can leave exposed wire from the connector. Use 12-gauge copper ground

wire for the single-ground connection. Use 8-gauge copper ground wire for the dual-ground connection.
