The GigaStack GBIC uses the following Cisco proprietary cables. See Figure 1-4 and Table 1-3 for more information.
The maximum distance for a GBIC-to-GBIC connection is 1 meter. The GigaStack GBIC requires Cisco proprietary signaling and cabling. For more information about cabling, see Appendix B, "Connectors and Cables."
Figure 1-4 GigaStack GBIC Cables
The 50-cm cable comes with the GigaStack GBIC. You can order additional cables.
Table 1-4 lists the switches and the module supporting the GigaStack GBIC.

1 The
1000BASE-X module provides one switched 1000-Mbps port in half-duplex,
full-duplex, or autonegotiation mode for a GigaStack GBIC. The port
supports the IEEE 802.3Z 1000BASE-X standard.
Switches and Module Supporting the GigaStack GBIC
To ensure support for redundant loop configurations when using the GigaStack GBIC in a cascaded stack configuration, make sure that every switch in the stack is running at least the minimum IOS Release listed in Table 1-5.
Note All switches in a series must run the same software version. For example, if the stack includes only Catalyst 2900 series XL and 3500 series XL switches, they must run Release 12.0(5)XU or later. If the stack includes a mixture of Catalyst 2900 series XL, 3500 series XL, 2950, and 3550 switches, all the 2900 XL and 3500 XL switches must run Release 12.0(5)XW or later, all the Catalyst 2950 switches must run Release 12.1(6)EA2 or later, and all the Catalyst 3550 switches must run Release 12.1(4)EA1 or later.
For more information, see the "Cascaded Stack Connections with a Redundant Link" section. For switch software upgrade information, refer to the release notes for your switch.
This section contains examples that use the GigaStack GBIC as a Gigabit uplink to aggregate traffic in a switched and shared network.
Figure 1-5 shows the GigaStack GBIC cascaded in a half-duplex stack configuration.

Figure 1-6 shows the 3500 XL switch aggregating traffic by using a GigaStack GBIC as a full-duplex, point-to-point uplink connection.
