Introduction
This document is a guide to cables and connectors for Catalyst 6500/6000, 5500/5000, and 4500/4000
series switching modules and Catalyst 2900/3500 XL, 2940, 2970, 2950/2955, 3550, and 3750 series fixedconfiguration switches. AC power supplies, connectors, and cords for these switches are also covered.
Prerequisites
Requirements
You should identify the part or model number of your switch/supervisor, switching module, or power
supply in order to use this document effectively. Do this by visual inspection, or issue the show module
command where possible.
Components Used
This document is not restricted to specific software and hardware versions.
Conventions
Refer to Cisco Technical Tips Conventions for more information on document conventions.
Console and Aux Port Cables
Different Catalyst Supervisor Engines use either a rolled or a straight-through cable in order to connect a
terminal or modem to the console port. Refer to these documents for information on how to connect a
terminal or modem to the console port of Catalyst series switches:
●
Connecting a Terminal to the Console Port on Catalyst Switches
●
Connecting a Modem to the Console Port on Catalyst Switches
Auxiliary (AUX) ports on Layer 3 (L3) switches or modules behave much the same way as AUX ports on
routers and are used to connect modems. Refer to Modem-Router Connection Guide for information on
how to connect a modem to an AUX port.
Which RJ-45 Ethernet Cable Do I Use?
A common question that concerns RJ-45 unshielded twisted pair (UTP) Ethernet cable concerns how to
distinguish between rolled, straight-through, and crossover cables, and when to use them. Use the
comparison guide found in the Types of RJ-45 Cabling section of Cabling Guide for Console and AUX
Ports in order to see the difference between these cables.
Cables to Hubs, Switches, Routers, and Workstations
Crossover and straight-through cables are used in order to connect switch ports or interfaces to network
devices. Consult this table in order to see when to use each of these cable types. Find the device in the lefthand column and match it up with another device in the top row. The intersection of these two devices
gives you the cable type used to connect them together.

Note: The ports on Catalyst switches that run Cisco IOS® Software (Native) can be configured to act as
Layer 2 (L2) or Layer 3 (L3) ports. When you connect the RJ-45 cable from a Layer 3 port, which acts as a
router port, to other devices, use the previous table. In summary, the cables used do not change, regardless
of whether the port is configured to be in Layer 2 (switch port) or Layer 3 (router port) mode.
Most Common Cable Connectors
These diagrams show some of the most common cable types and connectors used on Catalyst switches.
RJ-45
RJ-21 Telco
This is used in order to connect
to 10/100 or 10/100/1000
Ethernet ports and 1000Base-T
Gigabit Interface Converter
(GBIC) or small form factor
pluggable (SFP) GBIC ports.
10/100/1000 Ethernet ports must
use four twisted-pair Category 5,
5e or 6 cables.
This is used in order to connect
to 10/100BASE-TX RJ-21 telco
interfaces. Use Category 5 UTP
cables with male RJ-21.
MT-RJ Fiber-Optic

connect to 100Base-FX fiberoptic ports. Use multimode
fiber (MMF) cables with MTRJ connectors.
This is used in order to
connect to 100Base-FX,
1000Base-SX, Long
Wavelength/Long Haul (LX/
LH) and ZX fiber-optic
ports or GBICs. Use MMF
or single-mode fiber (SMF)
fiber-optic cable.
LC Fiber-Optic
This is used in order to connect to SFP
fiber-optic module ports.
StackWise
GigaStack
This is used in order to connect to
GigaStack GBIC ports. Cisco GigaStack
technology uses proprietary GBICs and
cables.
This is used in order to connect to StackWise ports on the rear
panel of Catalyst 3750 switches.
Cisco StackWise technology uses proprietary connectors and
cables.
GBIC and SFP Connectors
Many Catalyst switches, Supervisor Engines and switching modules have removable Gigabit Interface
Converters (GBICs) or small form factor pluggable (SFP)-type connectors. These diagrams show some of
the most common GBIC and SFP connectors used on Catalyst switches.
Note: A Catalyst 2950 switch is used for demonstration purposes.

AC Power Supplies, Connectors, and Cords for Catalyst
Switches
In this section you see the summary of AC power supplies, power connectors, and cords for Catalyst
6500/6000, 5500/5000 and 4500/4000 series, and Catalyst 3750, 2950, 2940, and 2900/3500XL series
switches. Refer to the Power Installation Guidelines in the tables that correspond in the next section for
international power requirements, DC power requirements, and other technical specifications.
Different Modules require different amount of power. Inline Power modules supplies the power to the IP
phones. Cisco has inline power module to power the IP phones. You have to choose the correct power
supply in order to support the various line cards, modules and Supervisor Engines on the switch. Cisco
offers a tool called the Cisco Power calculator which can be used in order to choose the correct power
supply for your switch. Launch the Cisco Power calculator and fill out the Product family, Supervisor
Engine, Input voltage, line cards and the number of PoE devices. IP phones are the example for PoE
devices and most of the IP phones belong to IEEE 802.3af Device - Class 2 (7W). Then the power
calculator shows the results of different choices of Power Supplies. From that you can choose the required
power supply. The power supplies successfully operate at their greatest capacity if the input voltage is
between 200 and 240 volts AC.
Catalyst 6500/6000 Series Switch Power Supplies and Cables
This table is a quick reference for the available power supplies and cables in North American standard.
Refer to Catalyst 6500 Power supply specifications for the detailed specifications you can. These few
points are important to know:
●
●
●
●
●
The 950W (PWR-950-AC), 950W DC (PWR-950-DC) and 1400W AC (PWR-1400-AC) are used
only with the Catalyst 6503 and Catalyst 6503-E Switches.
The Power supplies 1000W and 1300W can be used only with Catalyst 6506, 6509, and 6509-NEBA switches. The Supervisor Engines SUP32 and SUP720 are incompatible when 1000W and
1300W power supplies are used.
With a fully populated Catalyst 6513 switch, two 2500 W power supplies are not fully redundant.
If you operate the 2500 W power supply at the low range input (100 to 120 VAC), it is not
redundant in a fully populated Catalyst 6509, Catalyst 6509-E, Catalyst 6509-NEB, or Catalyst
6509-NEB-A switch.
The Power supplies 2500W, 2700W, and 3000W can operate at two different voltage levels
(110Vac and 220Vac). The Power supply output depends on the supplied input AC power. This
table shows the power ouput:

The AC power cords are hardwired to the 4000W Power supplies (WS-CAC-4000W-US=). It
supports only NEMA L6-30.
The 6000W power supply cannot be installed in the Catalyst 6503, Catalyst 6503-E, and Catalyst
6504-E switch chassis.
When 6000W power supply is used with the chassis Catalyst 6506, 6509, 6509-NEB, and 6509NEB-A, it operates at 4000W maximum output. It operates at 6000W maximum output when it is
used with Catalyst 6506-E, 6509-E, and 6513.
6000W power supply has two AC Power inputs. These are the various combinations of AC inputs
and the corresponding net power output:

Note: If you have 110Vac power inputs, you have to connect both the AC inputs of the 6000W
power supply in order to power on the switch.
●
The Catalyst 6500 series switches allow you to mix AC-input and DC-input power supplies in the
same chassis.
The modules have different power requirements, and some configurations require more power than a single
power supply can provide. The power management feature allows you to power all installed modules with
two power supplies. But, redundancy is not supported in this configuration because the total power drawn
from both power supplies is at no time greater than the capability of one supply. Refer the Power
Management and Environmental Monitoring of the Catalyst 6500 Software Configuration Guide for the
detailed explanation of Power redundancy.
Note: This document does not discuss the total power available with the currently shipped power supplies
for Catalyst 6500/6000 series switches or the amount drawn from each Catalyst 6500/6000 series line card.
Refer to the document Power Management for Catalyst 6000 Series Switches for this information.
