C H A P T E R 1 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.
Chapter 1 Overview GigaStack GBIC LEDs • Support for redundant loop configurations in a GigaStack GBIC stack For more information, see the “Minimum IOS Release for Redundant Loop Configurations” section on page 1-7 and the “Cascaded Stack Connections with a Redundant Link” section on page 2-12 • Support for IOS Release 12.0(5)XU or later for Catalyst 2900 XL and 3500 XL switches, support for Release 12.1(6)EA2 or later for Catalyst 2950 switches, and support for Release 12.

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.
Chapter 2 Installation Recommended Configuration Step 4 Secure the cable in a clip notch as shown in Figure 2-4. Securing the Cables in the GBIC Clip 32257 Figure 2-4 6 7 8 1 2 Clip installed on GBIC Step 5 Insert the GBIC into the slot. Follow the steps in the “Installing a GigaStack GBIC” section on page 2-4. Recommended Configuration All ports are set to autonegotiate the duplex mode for your GigaStack GBIC. You must keep this default setting; autonegotiation must not be disabled.

Chapter 2 Installation Creating Connections Point-to-Point Connections A point-to-point connection operates in full-duplex mode. Figure 2-6 shows an example of supporting switches with point-to-point connections.
Chapter 2 Installation Creating Connections Cascaded Stack Connections You can connect from three to nine switches in a cascaded stack configuration. The cascaded stack operates in half-duplex mode. Figure 2-7 shows the connections on some supporting switches.
Chapter 2 Installation Creating Connections Cascaded Stack Connections with a Redundant Link You can form a redundant link by connecting the open ports on the top and bottom GigaStack GBICs within the same stack, as shown in Figure 2-8.
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.
Chapter 2 Installation Power-On Self-Test Step 3 If you are using the GBIC clip to secure the GBIC cables, remove the clip from the GigaStack GBIC by pulling the tabs from the slots on the GBIC. Remove the cables from the notches in the clip. Step 4 Disconnect the cable from the GigaStack GBIC port. Warning Ultimate disposal of this product should be handled according to all national laws and regulations.
