The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: 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.

Modifying the equipment without Cisco???s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.

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:

???Turn the television or radio antenna until the interference stops.

???Move the equipment to one side or the other of the television or radio.

???Move the equipment farther away from the television or radio.

???Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Overview

The GigaStack GBIC (model WS-X3500-XL) adds port density and high-performance connectivity to supporting switches. When installed in a supporting switch, the GigaStack GBIC supports Gigabit connections in a cascaded stack or point-to-point configuration. The GigaStack GBIC autonegotiates the duplex setting of each port to maximize the bandwidth for your configuration.

Features

This section describes the GigaStack GBIC features:

???Half-duplex stacking using only one GBIC slot for each switch

Stack up to nine switches to form an independent backbone that can be managed with a single IP address. This stack gives the appearance of a single large switch for network management purposes. For this kind of connectivity, see the ???Example 1: Cascaded Stack Connection??? section on page 1-9.

???Full-duplex connectivity between two switches

You can also form a point-to-point link between two switches. The GigaStack GBIC supports one full-duplex link (in a point-to-point configuration) or up to eight half-duplex links (in a stack configuration) to other Gigabit Ethernet devices. For this kind of connectivity, see the ???Example 2: Point-to-Point Connection??? section on page 1-10.

Avoiding Electrostatic Discharge

Avoiding Electrostatic Discharge

Before you install the GigaStack GBIC, ground yourself by touching the metal part of the chassis to avoid electrostatic discharge (ESD). You should also keep the GigaStack GBIC in its antistatic shielded bag until you are ready for installation.

Installing a GigaStack GBIC

Gigabit Ethernet switches are shipped without the GigaStack GBIC. However, you can install the GBIC into GigaStack GBIC slots, as shown in Figure 2-1.

Install a GigaStack GBIC as follows:

Step 1 Remove the GigaStack GBIC from its protective packaging.

Step 2 If you want to use the GigaStack cable connector (hereafter referred to as the clip), see the ???Attaching the GBIC Clip??? section on page 2-6.

Step 3 Grip the sides of the GBIC with your thumb and forefinger, and insert it into the GBIC slot on a switch front panel, as shown in Figure 2-1, or the

Catalyst 2900 XL 1000BASE-X module slot, as shown in Figure 2-2.

The GigaStack GBIC is keyed to prevent incorrect insertion.

Step 4 Slide the GigaStack GBIC through the flap covering the opening into the slot until you hear a click. The click means the GigaStack GBIC is locked into the slot.

Chapter 2 Installation

Attaching the GBIC Clip

Attaching the GBIC Clip

Each GigaStack GBIC ships with a removable clip that can be attached to provide extra security against accidental cable removal. If you use the clip, you must attach it before inserting the GBIC into the slot.

Attach the clip as follows:

Step 1 Attach the clip to the GBIC by carefully inserting the clip tabs into the slots on either side of the GBIC, in the orientation shown in Figure 2-3. Slide the clip toward the port side of the GBIC.

Figure 2-3 Attaching the GBIC Clip

Step 2 Insert the cable connector into the GBIC port according to your configuration.

Step 3 Swing the GBIC clip up toward the GBIC so that the alignment bump in the clip seats in the indentation on the GBIC bottom.

Chapter 2 Installation

Creating Connections

Table 2-1 Available GBIC Ports in a Point-to-Point Configuration

Note The GigaStack GBIC supports setting a trunk to IEEE 802.1Q or Inter-Switch Link (ISL) encapsulation. All GigaStack GBIC interfaces in the cascaded stack should be configured as trunk interfaces (switchport mode trunk interface configuration command) and to use the same encapsulation method (switchport trunk encapsulation {isl | dot1q} interface configuration command). For more information on these commands, refer to the command reference for your switch.

For more information, see the ???Point-to-Point Connections??? section on page 2-10, the ???Cascaded Stack Connections??? section on page 2-11, and the ???Cascaded Stack Connections with a Redundant Link??? section on page 2-12.

Chapter 2 Installation

Removing a GigaStack GBIC

Caution A loop causes excessive collision errors on the port and can cause the link to become unstable. This instability decreases performance on the links, and communication between the switches in the stack is adversely affected.

If a Catalyst switch is connected through its GigaStack GBIC to another switch???s GigaStack GBIC that does not support loop detection, the GBIC LEDs turn these colors:

???The GigaStack GBIC LED on the switch without loop detection turns green almost immediately.

???The GigaStack GBIC LED on the switch with loop detection flashes green for 15 seconds and then turns green.

As a result, all GBIC links are enabled if no loop is created. If a loop is present, the software does not detect it, excessive collisions occur on these ports, no traffic passes through the stack, and the GigaStack GBIC LEDs remain green.

To avoid problems with loop configurations, make sure that all switches in your stack are running the appropriate IOS release as shown in Table 1-5 on page 1-8. For more information, see the ???Minimum IOS Release for Redundant Loop Configurations??? section on page 1-7. For switch software upgrade information, refer to the release notes for your switch.

Removing a GigaStack GBIC

Remove a GigaStack GBIC as follows:

Step 1 Release the GigaStack GBIC from the slot by simultaneously squeezing the two plastic tabs (one on each side of the GigaStack GBIC).

Step 2 To remove, slide the GigaStack GBIC out of the slot. A flap drops down to protect the internal connector.

Power-On Self-Test

All supporting switches perform a power-on self-test (POST) on the GigaStack GBIC. When you insert the GigaStack GBIC into the switch or module slot, the port LED on the switch or module turns amber while STP checks for possible loops and then turns green. When you insert a GigaStack GBIC cable into the GBIC port, the GigaStack GBIC port turns green if there is network connectivity; no additional configuration is needed. For more information about the LED meanings, see the ???GigaStack GBIC LEDs??? section on page 1-2 and the ???GBIC Module Slot LEDs??? section on page 1-3.
