Installation

This chapter describes how to install and remove the GigaStack GBIC.

The GigaStack GBIC can be installed while the switch is running and requires no configuration. You can manage GBIC ports as you would manage fixed ports on the switch. The web-based Visual Switch Manager (VSM) is a graphical interface for monitoring and controlling port features, and you can use the console port or Telnet to access the IOS command-line interface.

Inspecting the Packing List

Before you install a GigaStack GBIC, ensure that the following items are included in the package:


Figure 2-1: Package Contents


If anything is missing, contact your Cisco Systems customer service representative.

Note You can order a 1-m cable separately.

EMC Regulatory Statements

Avoiding Electrostatic Discharge

Before you install the GigaStack GBIC, ground yourself by touching a piece of metal to avoid electrostatic discharge (ESD). You should also take the following precautions to prevent damage to the GigaStack GBIC:

Installing a GigaStack GBIC

Gigabit Ethernet devices are shipped without the GigaStack GBIC installed. You can install the GBIC into GigaStack GBIC slots, as shown in Figure 2-2.

Note The GigaStack GBIC is not hot-swappable.

To install a GigaStack GBIC, do the following:

Step 1 Remove the GigaStack GBIC from its protective packaging.

Step 2 If you want to install the GigaStack cable connector (referred to hereafter as the clip) before inserting the GBIC into the switch, see "Installing the GBIC Clip" section.

Note You can attach the clip to the GigaStack GBIC either before or after you insert the GBIC into the switch.

Step 3 Grip the sides of the GBIC with your thumb and forefinger, and insert it into the GBIC slot on the front panel of the gigabit Ethernet switching module, as shown in Figure 2-2.

Note 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.

Installing the GBIC Clip

Each GigaStack GBIC now ships with a removable clip that can be attached to provide extra security against accidental cable removal. Install the clip as follows:

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


Figure 2-4: Attaching the GBIC clip


Note You can attach the clip to the GigaStack GBIC either before or after you insert the GBIC into the switch.

Step 2 Insert the cable connector into the GBIC receptacle 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 bottom of the GBIC.

Step 4 Secure the cable in the notches on the clip. Refer to Figure 2-4.


Figure 2-5: Securing the Cables in the GBIC Clip


Step 5 If you have not already done so, insert the GBIC into the switch.

Recommended Configuration

All ports are set to autonegotiate the duplex mode for your GigaStack GBIC. We recommend that you keep this default setting.

Connecting to GigaStack GBIC Ports

Insert the connector in the GigaStack GBIC receptacle, as shown in Figure 2-6.

Note The GigaStack GBIC LED is amber while Spanning Tree Protocol discovers the topology and searches for loops. This takes about 30 seconds. The port status LED then turns green.

Note Always use a GigaStack cable to connect GigaStack GBIC to any device. See the section "GigaStack GBIC Cabling" in the "Connectors and Cables" appendix for more information.

Creating Connections

You can create these configurations:

In a point-to-point configuration or stack configuration, the GigaStack GBIC can use the following ports to connect to other devices when inserted into the following devices:


Table 2-1: Point-to-Point Configuration
Device Available Port

3500 XL switches

1 or 2

1000BaseX module

1 or 2

For more information, see "Point-to-Point Configuration" and "Cascade Stack Configuration."

Point-to-Point Configuration

A point-to-point connection operates in full-duplex mode. Figure 2-7 shows a combination of 3500 XL switches and 1000BaseX modules in modular 2900 XL switches that establish a point-to-point connection.


Figure 2-7: Point-to-Point Configuration



Cascade Stack Configuration

You can connect from three to nine switches in a cascade stack configuration. The stack configuration operates in half-duplex mode. Figure 2-8 shows the various connections.


Figure 2-8: Stack Configuration Example


You can form a redundant link by connecting the open ports on the top and bottom GigaStack GBICs within the same switch, as shown in Figure 2-9.


Figure 2-9: Examples of Redundant-Link Stack Configuration



For more information about stacking configuration guidelines, see "Loop Configuration Support."

Removing a GigaStack GBIC

To remove a GigaStack GBIC, do the following:

Step 1 If you are using the GBIC clip to secure the GBIC cables, remove the clip from the GigaStack GBIC.

Step 2 Disconnect the cable from the GigaStack GBIC connector.

Step 3 Release the GigaStack GBIC from the slot by simultaneously squeezing the two plastic tabs (one on each side of the GigaStack GBIC).

Step 4 Slide the GigaStack GBIC out of the gigabit Ethernet module slot. A flap drops down to protect the gigabit Ethernet module connector.

Warning Ultimate disposal of this product should be handled according to all national laws and regulations.

Power-On Self-Test

All 3500 XL switches and modular 2900 XL switches perform a power-on self-test (POST) on the GigaStack GBIC if you insert it before you power-on the switch. These switches do not run POST on the GigaStack GBIC if you insert it after the switches power on.

When you insert a GigaStack GBIC into the switch or module slot, the port LED on the switch or module turns green. When you insert a GigaStack GBIC cable into the GBIC port, the GigaStack GBIC port turns green. This means that there is connectivity. For more information on the meaning of LEDs, see "Overview." For information about POST and troubleshooting, see "Troubleshooting."
