Electrical Equipment Guidelines

Follow these basic guidelines when working with any electrical equipment:

Telephone Wiring Guidelines

Use the following guidelines when working with any equipment that is connected to telephone wiring or to other network cabling:

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Port adapters and processor modules consist of printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, use a preventive antistatic strap during handling.

Following are guidelines for preventing ESD damage:

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohm.

12E/2FE Port Adapter LEDs

The 12E/2FE port adapter has an enabled LED, standard on all port adapters, and two status LEDs for each port. (See Figure 2-1.)


Figure 2-1: LEDs on the 12E/2FE Port Adapter (Horizontal Orientation Shown)


After system initialization, the enabled LED goes on to indicate that the port adapter has been enabled for operation.

The following conditions must be met before the 12E/2FE port adapter is enabled:

If any of the above conditions are not met, or if the initialization fails for other reasons, the enabled LED will not go on. Table 2-1 lists port LED status indications.


Table 2-1: 12E/2FE Port LED Indications
Port LED Status

LNK

This green LED goes on and remains on when the port is receiving a carrier signal from the network.

FDX1

This green LED remains off when the port is configured for half-duplex operation.
This LED goes on and remains on when the port is configured for full-duplex operation.

CO/FDX2

This green LED remains off when the port is configured for half-duplex operation and flashes on and off when there is a transmission collision on the network.
This LED goes on and remains on when the port is configured for full-duplex operation.

1The FDX LED is present on port  0 and port  1.
2The CO/FDX LED is present on port  2 through port  13.

12E/2FE Port Adapter Receptacles, Cables, and Pinouts

The interface connectors on the 12E/2FE port adapter are 14 individual RJ-45 receptacles. You can use all 14 receptacles simultaneously. The first two receptacles support IEEE  802.3, Ethernet, and IEEE  802.3u interfaces compliant with 10BASE-T and 100BASE-TX specifications. The remaining 12 receptacles support IEEE  802.3 and Ethernet interfaces compliant with 10BASE-T specifications.


Note Use Category  3 unshielded twisted-pair (UTP) crossover cables when connecting 10-Mbps 12E/2FE interfaces (port  2 through port  13) to a hub. Use Category  3 UTP straight-through cables when connecting 10-Mbps 12E/2FE interfaces to an end station.

Use Category  5 UTP crossover cables when connecting 10/100-Mbps 12E/2FE interfaces (port  0 and port  1) to a hub. Use Category  5 UTP straight-through cables when connecting 10/100-Mbps 12E/2FE interfaces to an end station.

12E/2FE interfaces do not support VLAN trunking.

Figure 2-2 shows the RJ-45 connectors. Table 2-2 lists the pinouts and signals for the RJ-45 connectors.


Figure 2-2: 12E/2FE RJ-45 Connections, Plug and Receptacle


Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables.

Note Referring to the RJ-45 pinout in
Table 2-2, proper common-mode line terminations should be used for the unused Category  3 and Category  5, UTP cable pairs 4/5 and 7/8. Common-mode termination reduces electromagnetic interference (EMI).

Depending on your 12E/2FE RJ-45 interface cabling requirements, use the pinouts shown in Figure 2-3 and Figure 2-4 for straight-through and crossover twisted-pair cable connections.

Crossover Cable Pinout, 12E/2FE RJ-45 Connections To a Hub


To identify the RJ-45 cable type, hold the two ends of the cable next to each other so you can see the colored wires inside the ends, as shown in Figure 2-5.


Figure 2-5: RJ-45 Cable Identification


Examine the sequence of colored wires to determine the type of RJ-45 cable as follows:

FCC Class B Compliance

The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco's installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.
