  • Page 9: Chapter 1 Product Overview

    Product Overview The Catalyst 2975 of switch is a stackable Ethernet switch to which you can connect devices like Cisco IP Phones, Cisco Wireless Access Points, workstations, and other network devices such as servers, routers, and other switches. The switch supports stacking through Cisco stack technology. Unless otherwise noted, the term switch refers to a standalone switch and to a switch stack.

  • Page 10: 10/100/1000 Poe Ports

    The switch delivers 15.4 W of PoE on any 24 of the 48 ports, or any combination of the ports deliver an average of 7.7 W of PoE at the same time, up to a maximum switch power output of 370 W. On a per-port basis, you can control whether or not a port automatically provides power when an IP phone or an access point is connected.

    The RPS is in standby mode or in a fault condition. See the RPS documentation for more information about the standby mode and fault conditions. The power supply in a switch has failed, and the RPS is providing power to the switch (redundancy has been allocated to this device).
  • Page 13 LED is off even if the powered device is connected to the switch port. Green PoE is on. The port LED is green only when the switch port is providing power. Alternating PoE is denied because providing power to the powered device will green and exceed the 370-W switch power capacity.
  • Page 14 (stack member) If your switches are stacked and you press the Mode button on any switch in the stack, all the switches change to display the same selected mode. For example, if you press the mode button on the stack master to display SPEED, all the other stack members display SPEED.
  • Page 15 Stack LEDs are amber when the ports are down. SFP module port LEDs 51 and 52 on the switch show the status for stack ports 1 and 2, respectively. If the port LEDs are green on all the switches in the stack, the stack is operating at full bandwidth. If any port LED is not green, the stack is not operating at full bandwidth.

    • Cisco IOS CLI You can fully configure and monitor the switch and switch cluster members from the CLI. You can access the CLI by connecting your management station directly to the switch console port or by using Telnet from a remote management station. See the switch command reference on Cisco.com for more information.

    The sequence in which the switches are first powered on might affect the switch that becomes the • stack master. If you want a particular switch to be the stack master, power on that switch first. This switch • becomes the stack master and remains the stack master until a master re-election is required. After 1 minute, power on the other switches in the stack.

    Switch POST Results As the switch powers on, it begins the power-on self-test (POST), a series of tests that runs automatically to ensure that the switch functions properly. It might take several minutes for the switch to complete POST.

    • For copper connections, determine if a crossover cable was used when a straight-through was required, or the reverse. Enable auto-MDIX on the switch, or replace the cable. See the for recommended Ethernet cables. Link Status Verify that both sides have link. A single broken wire or one shutdown port can cause one side to show link, but the other side does not have link.

    Clearing the Switch IP Address and Configuration If you have configured a new switch with a wrong IP address, or if all of the switch LEDs start blinking when you are trying to enter Express Setup mode, you can clear the configured IP address. The switch returns to the factory default settings.

    Reinstall any modules, and make cable connections. Turn on the replacement switch. The replacement switch has the same configuration for all the interfaces as the failed switch and functions the same as the failed switch. If you had manually set the member numbers for any members in the stack, you need to manually assign the replacement switch with the same member number as the failed switch.
