The GLX4000 switch is scalable by accepting up to three modular port cards with 48 ports per card. Two port card versions are available with small form factor pluggable (SFP) transceivers – non-retimed and retimed. Each SFP transceiver is hot-swappable and provides the physical ports for various media. Different types of SFP transceivers support a variety of network configurations. Another port card version accepts Firewire (1394B) signals directly at up to1600 MB/s. Another port card accepts XFP transceivers for10 GB/s protocols.
GLX4000 switches come equipped with hot-swappable power supplies, fans and port cards to allow users to quickly add or replace parts without impacting system up-time. A Compact Flash module acts as the unit’s disk drive for the controller’s CPU and can be removed for security reasons. The GLX4000 Linux® operating system, controlling firmware, and nonvolatile port configuration data reside on the module.
