Hardware Overview
Ports
The following port types are supported on Foundry Stackable devices and Chassis devices.
1000BaseT Gigabit Copper (GC) Ports
The 1000BaseT Gigabit Copper (GC) ports are fully compliant with the IEEE 802.3ab standard and can provide
Gigabit throughput over standard category-5 ("Cat-5") copper wiring. The port connectors are RJ-45s, the same
as the connectors on Foundry's 10/100 modules. Thus, you can immediately deploy the GC ports without
recabling.
Packet Over SONET (POS) Ports
The POS ports use SC duplex connectors. For more information, see "Using Packet Over SONET (POS)
Modules" on page 6-1.
10BaseT/100BaseTX Ports
The 10BaseT/100BaseTX ports are auto-sensing, auto-negotiating ports with RJ-45 UTP connectors. These
ports accept category-5 Unshielded Twisted Pair (UTP) cables.
See "Connecting Network Devices" on page 2-22 for cabling pinouts and signalling specifics. If you prefer to
avoid assembling cables by hand, you can order the proper cables from Foundry Networks.
100BaseFX Ports
The 100BaseFX ports are equipped with MT-RJ connectors and operate at 100 Mbps in full-duplex mode.
1000BaseSX Ports
The 1000BaseSX ports operate in full-duplex mode and are equipped with SC connectors on fixed-configuration
modules and come as mini-GBICs for mini-GBIC modules that support this port type. Multi-mode fiber cabling is
supported.
1000BaseLX
The 1000BaseLX ports operate in full-duplex mode and are equipped with SC connectors on fixed-configuration
modules and come as mini-GBICs for mini-GBIC modules that support this port type. Both single-mode fiber
(SMF) and multi-mode fiber (MMF) cabling is supported. The 1000BaseLX ports must be connected to another
1000BaseLX port. Connection to a 1000BaseSX port is not supported.
1000BaseLH
The 1000BaseLH ports operate in full-duplex mode and are equipped with SC connectors on fixed-configuration
modules and come as mini-GBICs on mini-GBIC modules that support this port type. Single-mode fiber cabling is
supported.
NOTE: 1000BaseSX, 1000BaseLX, and 1000BaseLH ports also support auto-negotiation when the auto-gig
option is enabled on the system.
NOTE: 1000BaseSX, 1000BaseLX, and 1000BaseLH ports operate only at full-duplex.
Port Connectors
10/100BaseTX ports come with RJ-45 connectors.
100BaseFX ports come with MT-RJ connectors.
1000BaseSX, 1000BaseLX, and 1000BaseLH ports come with dual SC connectors.
1000BaseFX, 1000Base-LX, and 1000BaseLH ports also are available as mini-GBIC ports for the modules that
support mini-GBICs and these interface types.
