AC power supplies, connectors, and cords for these switches are also covered. 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: Note: The ports on Catalyst switches that run Cisco IOSĀ® 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. 1 LX/LH GBICs require a mode-conditioning patch cord between the GBIC and MMF. Refer to the Mode-Conditioning Patch Cord section of the document Connector and Cable Specifications for more information. Catalyst 5500/5000 Connectors and Cables Identify the switching module part number. Use this table in order to match up the part number with the type of connector and cable used. Note: This guide does not cover Catalyst 5000 Fiber Distributed Data Interface (FDDI) and Copper Distributed Data Interface (CDDI) cables, Catalyst 5000 ATM cables, or Catalyst 5000 Token Ring cables. Refer to Installation Preparation for cabling and specifications for these modules. 1 Category 3 UTP cable can transmit data at speeds of up to 10 Mbps and therefore is only used for 10 Mbps network devices. Catalyst 5000 10Base-T telco switching modules can use Category 3 cable, but Category 5 cable is required for all other 10/100 Base-TX switching modules. 2 LX/LH GBICs require a mode-conditioning patch cord between the GBIC and MMF. Refer to the Mode-Conditioning Patch Cord section of the document Connector and Cable Specifications for more information. Catalyst 3750 Connectors and Cables Identify the switch chassis part number. Use this table in order to match up the part number with the type of connector and cable used. Note: The Catalyst 3750 switch ships with a 0.5-meter StackWise cable that you can use in order to connect the StackWise ports on the rear panel. You can also order these StackWise cables from your Cisco sales representative: Catalyst 2970 Connectors and Cables Part Number Connector Type Cable Type Cable/Connector Specifications WS-C2970G-24T 24 10/100/1000 Ethernet RJ-45 Category 5, 5e, or 6 UTP Catalyst 2970 Hardware Guide WS-C2970G-24TS 24 10/100/1000 and 4 SFP module slots RJ-45 (for 10/100/1000 ports) Category 5, 5e, or 6 UTP SFP: RJ-45 (for 1000Base-T) or LC fiber-optic (for 1000Base-SX/LX/ZX) SFP: Cat5, 5e, or 6 UTP or SMF/MMF fiber-optic Catalyst 2950/2955 Connectors and Cables Identify the switch chassis part number. Use this table in order to match up the part number with the type of connector and cable used. Note: This guide does not cover the Catalyst 2950 Long-Reach Ethernet (LRE) Switches. Refer to Long-Reach Ethernet Products for more information on cabling and specifications. Note: Some Catalyst 2950 switches support the GigaStack GBIC, which requires a Cisco proprietary cable of either CAB-GS-50CM (0.5-meter cable) or CAB-GS-1M (1-meter cable). Catalyst 2900/3500 XL Connectors and Cables Identify the switch chassis or expansion module part number. Use this table in order to match up the part number with the type of connector and cable used. Note: This guide does not cover the WS-C2912-LRE-XL or WS-C2912-LRE-XL switches. Refer to the Long-Range Ethernet Ports section of Product Overview (Catalyst 2900 Series XL switches) for more information on cabling and specifications. Note: Some Catalyst 3500XL switches support the GigaStack GBIC, which requires a Cisco proprietary cable of either CAB-GS-50CM or CAB-GS-1M. 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: Catalyst 2900/3500XL, 2940, 2950, 3550 and 3750 Series Switch Power Supplies and Cables Catalyst 2900/3500, 2940, 2950, 3550 and 3750 switches require standard 110V, 15 Amp AC input Power. Refer to these Hardware Installation Guides for the detailed power specifications: RJ-21 to RJ-45 Pin-Out Pattern All Catalyst family 10/100TX telco switching modules incorporate industry-standard RJ-21 connectors and require compatible Category 5 cabling systems to achieve 100 Mbps data rates. 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.
