Page 45: Overview
Catalyst switches are a series of Ethernet switches that you can use to connect any Ethernet-enabled devices. The Catalyst 2955 switch is an Ethernet switch that mounts on a DIN rail in an industrial enclosure as well as in a standard 19-inch rack. Its components are designed to withstand extremes in temperature, vibration, and shock so that the switch can be deployed in an industrial environment.

Uplink port status LEDs Power Status LEDs The Catalyst 2955 switch can operate with one or two power supplies. Each power supply input has an associated LED that shows the power supply status. If the switch is in single-power mode and only power supply A is present and functioning, the LED for power supply B is green, and the LED for power supply A shows its status.
Page 57 Table 2-1 Note The power status LEDs show that power is not present on the switch if the power input drops below 17 V. The power status LEDs only show that power is present if the voltage at the switch input exceeds 18.5 V. The 1.5 V difference, or hysteresis, ensures that the power status LEDs do not oscillate at values near 18 V.

You can manage switches by using command-line entries. To access the CLI, connect a PC or terminal directly to the console port on the switch. If the switch is attached to your network, you can use a Telnet connection to manage the switch from a remote location.
Page 64 • You can manage switches by using an SNMP-compatible management station running platforms such as HP OpenView and SunNet Manager. The switch supports a comprehensive set of MIB extensions and MIB II, the IEEE 802.1D bridge MIB, and four Remote Monitoring (RMON) groups. For more information, see the documentation that came with your SNMP application.

Decide where you want to install the switch. Connecting the Switch to the Power Converter The Catalyst 2955 switch can be used with an optional AC/DC power converter (PWR-2955-AC=) in a nonhazardous location installation. To prevent the Catalyst 2955 switch from overheating, there must be a minimum Caution of 3 inches between any other device and the top, bottom, or sides of the switch.
