Front-Panel Description Chapter 1 Product Overview GBIC Module Slots The Cisco Gigabit Interface Converter (GBIC) module slots support the following modules to provide flexibility in media and distance options: • 1000BaseSX GBIC module for fiber connections of up to 550 meters. • 1000BaseLX/LH GBIC module for fiber connections of up to 10 kilometers. • 1000BaseZX GBIC module for fiber connections of up to 100 kilometers. • GigaStack GBIC module for creating a 1-Gbps stack configuration of up to nine Catalyst 3500 XL switches. The GigaStack GBIC supports one full-duplex link (in a point-to-point configuration) or up to nine half-duplex links (in a stack configuration) to other Gigabit Ethernet devices. Using the required Cisco proprietary signaling and cabling, the maximum distance for a GigaStack GBIC-to-GigaStack GBIC connection is 1 meter. You can install up to two GBICs in the Catalyst 3512, 3524, 3524-PWR and 3548 XL switches and up to eight GBICs in the Catalyst 3508G XL switch. Note GBIC modules are not factory-installed on these switches, but you can order GBIC modules separately. Figure 1-7 and Figure 1-8 show how a GBIC module is inserted into a GBIC module slot on the switch. Refer to the documentation that came with your GBIC module for complete GBIC module information. 1-10 Catalyst 3500 Series XL Hardware Installation Guide 78-6456-03
