3. Hardware Port & Slot Layout

Rear Panel Fixed Ports

1. 48 × 10/100/1000BASE-T RJ45 Host Ports
   Auto-sensing 1G copper interfaces compliant with IEEE 802.3ab Gigabit Ethernet. Supports lossless FCoE transport over CAT5e/CAT6 cabling via IEEE DCB PFC/ETS standards; all Layer 2, SAN and security policies are enforced centrally on the parent switch, not the FEX itselfCisco Russ....
2. 4 × SFP+ 10G Fabric Uplink Ports (Yellow Labeled)
   Wire-speed 10G Ethernet uplinks for fabric connectivity to the upstream parent switch. Supports SFP+ optical transceivers (SR, LR, ER), passive Twinax DAC cables and dedicated FET-10G fabric extender transceivers. Multiple uplinks can be bundled into LACP port-channels for load balancing and link failure redundancyManualsLib.

Front Panel Redundant FRU Slots

1. Two independent hot-swappable AC power supply bays (N+1 redundant deployment supported)
2. Two independent hot-swappable fan tray slots (dual-fan redundancy eliminates single cooling point of failure)
