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.

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.

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.

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.

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.
