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
fixed-configuration switches. AC power supplies, connectors, and cords
for these switches are also covered.
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.
Note: A Catalyst 2950 switch is used for demonstration purposes.
GBIC and SFP support depends on the platform and software version. Refer to these documents for GigabitEthernet system requirements, as well as GBIC system requirements, Coarse Wave Division Multiplexer (CWDM) GBIC, Gigastack GBIC, and SFP system requirements:

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.
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.
Refer to Catalyst 4000 Series Installation Guide - Site Planning for the list of Catalyst 4000 Power supplies, cables and the corresponding part numbers.
Category 5 telco cables can be ordered directly from Cisco. Refer to Cisco.com for ordering information. This is the information on Cisco part numbers.
This table shows the pin-out pattern used on Catalyst 10/100TX (and 10BaseT) RJ-21 switching modules.
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
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 left-hand 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.| Hub | Switch | Router | Workstation | |
|---|---|---|---|---|
| Hub | Crossover | Crossover | Straight | Straight |
| Switch | Crossover | Crossover | Straight | Straight |
| Router | Straight | Straight | Crossover | Crossover |
| Workstation | Straight | Straight | Crossover | Crossover |
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.

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-NEB-A 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:
Power Supply Power Output at 110Vac, 16A Power Output at 220Vac, 16A 2500W 1300W 2500W 2700W 1350W 2700W 3000W 1400W 3000W
- 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 6509-NEB-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:
6000W Power Supply Power Options AC Input 1 AC Input 2 Net Power Supply Output 110Vac, 16A Not Connected No Power Output Not Connected 110Vac, 16A No Power Output 110Vac, 16A 110Vac, 16A 2900W 220Vac, 16A Not Connected 2900W Not Connected 220Vac, 16A 2900W 110Vac, 16A 220Vac, 16A 2900W 220Vac, 16A 110Vac, 16A 2900W 220Vac, 16A 220Vac, 16A 6000W
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.
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.
