SpecificationItem
15 lbs. (6.80 kg) fully loadedWeight
16 Fibre Channel 4 GB / 2 GB / 1 GB ports (upgradeable in
4-port increments, full-duplex, auto-negotiating for compatibility
with existing 2Gb and 1Gb devices), 4 Fibre Channel 10 GB
XPAK MSA-compliant ports (full-duplex), 1 Ethernet 10/100 BaseT
with RJ45 port
Ports per chassis
• Supports all topologies, including: stack, cascade, cascaded
loop, and mesh with E_Port
• Supports multiple links between switches
• In-order delivery of frames in all Multi-switch and multi-link
configurations
• Adaptive Trunking and Intelligent Path Selection on all 10Gb
ports
Multi switch fabrics
All ports can assume the following states:
• F_port: Fabric
• FL_port: Fabric loop (public loop)
• E_port: Switch-to-switch
• Ports are auto-discovering, self-configuring
Fabric port types
• Hot-pluggable, industry-standard SFPs (Small Form Pluggable)
for 4Gb ports
• Hot-pluggable, industry-standard XPAK optics or copper
stacking cables for 10Gb ports
Media type
