The GigaStack GBIC allows you to 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. 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. The GigaStack GBIC can add port density to a 3500 XL or 2900 XL network. You can install the GigaStack GBIC in a 3500 XL switch or into a 1000BASE-X module that resides in a modular 2900 XL switch. When installed in a 3500 XL switch or a 2900 XL module, the GigaStack GBIC supports 1000BASE-X connections. The GigaStack GBIC autonegotiates the duplex settings of each port to maximize the bandwidth for your configuration.
The maximum distance for a GigaStack GBIC-to-GigaStack GBIC connection is 1 meter. The GigaStack GBIC requires Cisco proprietary signaling and cabling. For more information on cabling, see the section entitled "Cabling Guidelines."
