3. Hardware Port & Slot Layout

Rear Panel Fixed Ports

1. 32 × 100M/1G/10GBASE-T RJ45 Host Ports
   Auto-sensing triple-speed copper interfaces compliant with IEEE 802.3an 10GBASE-T and IEEE DCB lossless standards (PFC, ETS). Supports lossless FCoE transmission over CAT6a/CAT7 cabling up to 30 meters. All Layer 2, SAN and security policies are enforced centrally on the parent switch, not the FEX itself.

   Wire-speed 40G Ethernet/FCoE uplinks for high-capacity leaf-spine fabric connectivity to upstream parent aggregation/spine switches. Each QSFP+ port breaks out to four independent 10G channels via splitter cables, expanding total uplink 10G capacity to 16 ports. All four uplinks can be bundled into LACP port-channels for load balancing and full link redundancy.

Front Panel Redundant FRU Slots

1. Two independent hot-swappable AC power supply bays (1+1 redundant deployment supported)
2. Three independent hot-swappable fan tray slots (2+1 redundant cooling architecture to eliminate single cooling failure points)
