|
Warning Only trained and qualified personnel should be allowed to install or replace this equipment. |
|
Warning Connect the unit only to DC power source that complies with the safety extra-low voltage (SELV) requirements in IEC 60950 based safety standards. |
|
Caution You must connect the switch only to a DC-input power source that has an input supply voltage from 18 to 30 VDC. If the supply voltage is not in this range, the switch might not operate properly or might be damaged. |
|
Caution The switch must be installed with 2 A-branch-circuit protection. |
|
Caution This installation must comply with all applicable codes. |
To wire the switch to the optional AC/DC converter, proceed to the "Connecting the Switch to the AC/DC Converter" section.
To wire the switch to a DC-input power source, follow these steps:
Step 2 Identify the positive and return feed positions for the power and relay connector. The positive DC power input for power supply A is labeled 24V A, and the return for power supply A is labeled RTN A. For power supply B (the redundant power supply), the positive DC power input is labeled 24V B, and the return is labeled RTN B.
Step 3 Measure two strands of twisted-pair copper wire (18 to 20 AWG) long enough to connect to the DC power source.
Step 4 Using an 18-gauge wire-stripping tool, strip each of the two twisted pair wires coming from each DC-input power source to 0.25 inch (6.3 mm) ± 0.02 inch (0.5 mm). Do not strip more than 0.27 inch (6.8 mm) of insulation from the wire. Stripping more than the recommended amount of wire can leave exposed wire from the power and relay connector after installation.
Step 5 Insert the exposed DC-input power source wires into the power and relay connector, as shown in Figure 2-7. Make sure that you cannot see any wire lead. Only wire with insulation should extend from the connector.
Step 6 Use a ratcheting torque flathead screwdriver to torque the power and relay connector captive screw (above the installed wire lead) to 4.5 in-lbs. (72 ozf-in.). (See Figure 2-8.)
|
Caution Do not overtorque the power and relay connector captive screws. The recommended maximum torque is 4.5 in-lbs. |
|
Note If you are connecting a second power supply, repeat Step 4 through Step 6 for the DC-input (24V B) and return (RTN B) for power supply B. |
Figure 2-9 shows the completed DC-input wiring for two power supplies on a power and relay connector.
|
Note If you plan to connect external alarm devices to the alarm relays, proceed to the "Wiring the External Alarm Device Relays" section. Otherwise, proceed to the next step. |
Step 7 Proceed to the "Add the Ferrite to the Power and Relay Connector Wiring" section for instructions on how to attach the ferrite to the power and relay connector wiring.
The Catalyst 2955 switch can be used with an optional AC/DC power converter (PWR-2955-AC) in a nonhazardous location installation.
|
Caution The AC/DC power converter (PWR-2955-AC) can only be used in a nonhazardous location installation. For instructions on how to install the AC/DC power converter on a DIN rail, refer to the instructions that came with the device. |

Step 2 Locate the power and relay connector (see Figure 2-5).
Step 3 Identify the positive and return feed positions for the power and relay connector. The positive DC power input for power supply A is labeled 24V A, and the return for power supply A is labeled RTN A. For power supply B (the redundant power supply), the positive DC power input is labeled 24V B, and the return is labeled RTN B.
Step 4 Measure two strands of twisted-pair copper wire (18 to 20 AWG) long enough to connect to the AC/DC power converter.
Step 5 Using an 18-gauge wire-stripping tool, strip both ends of each of the two twisted pair wires coming from the power source to 0.25 inch (6.3 mm) ± 0.02 inch (0.5 mm). Do not strip more than 0.27 inch (6.8 mm) of insulation from the wire. Stripping more than the recommended amount of wire can leave exposed wire from the power and relay connector after installation.
Step 6 Insert the exposed power source wires into the power and relay connector, as shown in Figure 2-7. Make sure that you cannot see any wire lead. Only wire with insulation should extend from the connector.
Step 7 Use a ratcheting torque flathead screwdriver to torque the power and relay connector captive screw (above the installed wire lead) to 4.5 in-lbs. (72 ozf-in.). (See Figure 2-8.)
|
Caution Do not overtorque the power and relay connector captive screws. The recommended maximum torque is 4.5 in-lbs. |
Step 8 Connect the other end of the twisted-pair wire to the AC/DC converter terminal block. For instructions on how to wire the AC/DC converter terminal block, refer to the documentation that accompanied the device.
|
Note If you are connecting a second power supply, repeat Step 3 through Step 8 for the input (24 V B) and return (RTN B) for power supply B. |
Figure 2-9 shows the completed wiring for two power supplies on a power and relay connector.
|
Note If you plan to connect external alarm devices to the alarm relays, proceed to the "Wiring the External Alarm Device Relays" section. Otherwise, proceed to the next step. |
Step 9 Proceed to the next section, "Add the Ferrite to the Power and Relay Connector Wiring" for instructions on how to attach the ferrite to the power and relay connector wiring.
Before you connect the power and relay connector to the front panel, follow these steps to add a ferrite to the power and relay connector wiring.
|
Note If you plan to connect external alarm devices to the alarm relays, first proceed to the "Wiring the External Alarm Device Relays" section. |
Step 2 Loop the cable around the ferrite and back through the center to secure the ferrite. See Figure 2-11 for details.
Step 3 Proceed to the "Attach the Power and Relay Connector to the Switch" section for instructions on how to attach the power and relay connector to the front panel of the switch.
Follow these steps to attach the power and relay connector to the front panel of the switch.
|
Caution Secure the wires coming from the power and relay connector so that they cannot be disturbed by casual contact. For example, use tie wraps to secure the wires to the rack. |
Step 2 Use a flathead screwdriver to tighten the captive screws on the sides of the power and relay connector.
Follow these steps to power on the switch:
After the power is connected, the switch automatically begins POST, a series of tests that verifies that the switch functions properly.
|
Note The uplink port status LEDs provide system and status information during POST. On the Catalyst 2955C-12 and Catalyst 2955S-12, the uplink ports are labeled 13 and 14. On the Catalyst 2955T-12, the uplink ports are labeled 1 and 2. |
When the Catalyst 2955C-12 and Catalyst 2955S-12 begin POST:
When the Catalyst 2955T-12 begins POST:
If POST completes successfully on the Catalyst 2955C-12 and Catalyst 2955S-12:
If POST completes successfully on the Catalyst 2955T-12:
If POST fails on the Catalyst 2955C-12 and Catalyst 2955S-12:
If POST fails on the Catalyst 2955T-12:
If your switch fails POST, see "Troubleshooting," to determine a corrective action.
|
Note Call Cisco Systems immediately if your switch does not pass POST. |
While the switch powers on, the power status LEDs are green or red, showing the presence or absence of power supplies (see Table 1-1 for details). During POST, the power status LEDs are green. After POST completes successfully, the power status LEDs are green if both power supplies are functioning normally and the switch has been configured to operate in dual power mode.
If the switch is configured to operate in single power mode operation, only the primary power status LED turns green. If the primary power supply is not functioning normally or is not present, the power status LED turns red. Refer to the switch configuration guide for details on single and dual power mode operation.
On a Catalyst 2950 switch, you can use the MODE button to recover the switch password. The Catalyst 2955 switch has no MODE button, so the boot loader compensates by using break key detection to stop the automatic boot sequence for password recovery.
On the Catalyst 2955C-12 and Catalyst 2955S-12 switches, during the initial appearance of the boot loader prompt on the console after POST, uplink port 13 LED blinks green, and uplink port 14 LED is off. On the Catalyst 2955T-12 switch, during the initial appearance of the boot loader prompt on the console after POST, uplink port 1 LED blinks green, and uplink port 2 LED is off.
|
Note Refer to the switch software configuration guide for details on the Catalyst 2955 switch password recovery process. |
After successfully running POST, follow these steps.
Step 2 Disconnect the cables.
Step 3 Decide where you want to install the switch.
The alarm relays on the Catalyst 2955 switch are normally open (NO). To connect an external alarm device to the relays, you must connect two relay contact wires to complete an electrical circuit. Because each external alarm device requires two connections to a relay, the Catalyst 2955 switch supports a maximum of two external alarm devices.
After you have completed the wiring for the DC power connections, follow these steps to wire the switch to an external alarm device:
|
Note This procedure is optional. |
Step 2 Use a wire stripper to remove the casing from both ends of each wire to 0.25 inch (6.3 mm) ± 0.02 inch (0.5 mm). Do not strip more than 0.27 inch (6.8 mm) of insulation from the wires. Stripping more than the recommended amount of wire can leave exposed wire from the power and relay connector after installation.
Step 3 Insert the exposed wires for the external alarm device into the wire entry holes for the alarm relay contacts, as shown in Figure 2-13.
Step 4 Use a ratcheting torque flathead screwdriver to torque the power and relay connector captive screw (above the installed wire leads) to 4.5 in-lbs. (72 ozf-in.). (See Figure 2-14 for details.)
|
Caution Do not overtorque the power and relay connector captive screws. The recommended maximum torque is 4.5 in-lbs. |
Step 5 Repeat Step 1 through Step 4 to connect the input and output wires of an additional external alarm device.
Figure 2-15 shows the completed wiring for two power supplies and two external alarm devices on a power and relay connector.
|
Note See the "Add the Ferrite
to the Power and Relay Connector Wiring" section for
