    Refer to page... Overview PoE (Power over Ethernet) Support Connectivity Management Standards Compatibility LANVIEW Diagnostic LEDs Overview The C3G124‐24P and C3G124‐48P are stackable switches that can be adapted and scaled to  help meet your network requirements. These switches provide a management platform  and an uplink to a network backbone for a stacked group of up to eight C3 switches.  You can also use a redundant DC power supply with these switches to help prevent  downtime due to an internal power supply failure in the switch or AC power source. You can install the switch on a flat surface or into a standard 19‐inch rack with user‐ supplied mounting hardware, and configure the switch functions using the WebView™  application, CLI switching commands, and/or SNMP. C3G124-24P Stackable Switch The C3G124‐24P (Figure 1‐1) has several types of front panel port connections, which  include: • Twenty‐four RJ45 ports (10/100/1000 Mbps, 1000BASE‐T copper ports) that also  support PoE for connections to IEEE 802.3af compliant PDs (powered devices).

    Note: The Mini-GBIC ports cannot be active simultaneously with their corresponding 10/100/1000BASE-T ports. For example, if SFP port 24 establishes a link first on the C3G124-24P, the 10/100/1000BASE-T built-in RJ45 port 24 is not available and vice-versa. • Rear panel connectors for high‐speed connections in a stack configuration.

Power over Ethernet (PoE) refers to the ability to provide 48 Vdc power to a powered  device using the same Ethernet cabling that provides data. Modern Ethernet  implementations employ differential signals over twisted pair cables. This requires a  minimum of two twisted pairs for a single physical link. Both ends of the cable are  isolated with transformers blocking any DC or common mode voltage on the signal pair.  PoE exploits this fact by using two twisted pairs as the two conductors to supply a direct  current. One pair carries the power supply current and the other pair provides a path for  the return current. While several proprietary legacy implementations of PoE have been  deployed by LAN equipment vendors, in 2003 the IEEE published the IEEE 802.3af‐2003  specification, which is part of the 802.3 suite of standards. The switch is fully compliant with the IEEE 802.3af standard. It supports the standard  resistor‐based detection method, as well as AC disconnect capability. The switch is also  capable of supplying 7.5 watts of power to all ports simultaneously. Support is also  provided for the 802.3af‐defined maximum of 15.4 watts. Each PD (Powered Device) has a PDC (Powered Device Classification) that is transmitted  to the switch for power management purposes. Table 1‐1 on page 1‐5 lists the  classifications and the associated power ranges.

  • Page 39: Connecting High-Speed Stacking Cables

    Connecting High-Speed Stacking Cables Connecting High-Speed Stacking Cables The stack of switches can be connected in a ring or daisy chain topology. In a ring  topology all the switches are connected. The only difference in the cable connections in a  daisy chain topology is that one cable is not installed. Up to 8 switches can be stacked together using high‐speed stacking cables. You can add  switches and reach up to a maximum of 384 Ethernet ports per stack. The high‐speed  stacking cables allow the entire stack to operate with a single IP address.  The high‐speed stacking cables are optional items and must be ordered separately. The  C3G124‐24P and C3G124‐48P support three types of SecureStack stacking cables: • C2CAB‐SHORT cable to connect two adjacent switches in the stack. If the stack is in a  configuration where the adjacent switches are too far apart for the SHORT cables, the  LONG cable can be used for the connections. • C2CAB‐LONG cable to connect from the top switch to the bottom switch in the stack.  You need only one C2CAB‐LONG cable per stack. • C2CAB‐5M cable to connect from the top switch to the bottom switch in the stack  when these two switches are physically located in seperate mounting racks and  require a longer cable reach. Figure 3‐7 shows an example of a four‐high stack connected in a ring topology. All  STACK DOWN and STACK UP connectors are used in the installation. The high‐speed  stacking cable (1) connections are from the STACK DOWN connector (2) of one switch to  the STACK UP (3) connector of the next switch up in the stack. A high‐speed stacking  cable connection from the STACK DOWN (4) connector of the switch at the top of the  stack to the STACK UP (5) connector at the bottom of the stack completes the ring  connection. In a daisy chain topology, the last cable connection is not made.

  • Page 41 Configuring Switches in a Stack Once installed in a stack, the switches behave and perform as a single switch. As such,  you can start with a single switch and add more switches as your network expands. You  can also mix different products in the family in a single stack to provide a desired  combination of port types and functions to match the requirements of individual  applications. In all cases, a stack of switches performs as one large product, and is  managed as a single network entity. When switches are installed and connected as described back in “Connecting High‐Speed  Stacking Cables” on page 3‐11, the following occurs during initialization: • The switch that will manage the stack is automatically established and is referred to as  the Manager switch. • All other switches are established as Member switches in the stack.  • The hierarchy of the switches that will assume the function of backup manager is also  determined in case the current manager malfunctions, is powered down, or is  disconnected from the stack.  • The Console port on the manager switch remains active for out‐of‐band (local) switch  management, but the Console port on each member switch is deactivated. This  enables you to set the IP address and system password using a single Console port.  Now each switch can be configured locally using only the manager’s Console port, or  in‐band using a remote device and the CLI set of commands described in this section.  For procedures used for various types of connections to the Console port, refer to  “Connecting to Console Port for Local Management” on page 3‐18. Once a stack is created (more than one switch is interconnected), the following occurs: Switch (unit) IDs are arbitrarily assigned on a first‐come, first‐served basis. Switch IDs are saved against each module. Then, every time a board is power‐cycled,  it will initialize with the same switch ID. This is important for port‐specific  information (for example: ge.4.12 is the 12th Gigabit Ethernet port on switch  number 4). The management election process uses the following precedence to assign a  management device: Previously assigned/elected management switch b.

To connect an MT‐RJ cable to a fixed MT‐RJ connector of a Mini‐GBIC, refer to Figure 3‐18  and proceed as follows: Remove the protective covers (not shown) from the front panel MT‐RJ fiber‐optic port  (port 46 in this example) and from the connectors on each end of the cable. Note: Leave the protective covers in place when the connectors are not in use to prevent contamination. Caution: Do not touch the ends of the fiber-optic strands, and do not let the ends come in contact with dust, dirt, or other contaminants.
