Features
The Cisco Nexus 5596UP switch is a top-of-rack, 10-Gigabit Ethernet and Fibre channel over Ethernet
(FCoE) switch offering up to 1920 Gigabit throughput and up to 96 ports. The switch has 48 1- and
10-Gigabit Ethernet and FCoE ports and three expansion slots. As a top-of-rack switch, all the servers
in the rack connect to the Cisco Nexus 5596UP switch, and it connects to the LAN or SAN.
The Cisco Nexus 5596UP switch has the following features:
• 48 fixed 1- and 10-Gigabit Ethernet server connection ports on the back of the switch
• Three slots on the back of the switch for optional expansion modules, which can be either a 16-port
10-Gigabit generic expansion module 2 (GEM2) or a layer 3 GEM2
• Two slots on the front of the switch for hot swap-capable power supplies, which provide
front-to-back airflow for cooling (the Cisco Nexus 5596T and 5596UP switches alternatively
support back-to-front [port-side intake] airflow)
• Four slots on the front of the switch for hot swap-capable fan modules.
• Layer 2 or Layer 3 I/O modules
• One USB port on the front of the switch
Note Hot swapping of normal air flow fans and power supplies with reverse airflow fans and power supplies
is not supported on the Cisco Nexus 5000 switches. Hot swapping of fans and power supplies is only
supported if they are replaced with the same direction parts.
Chassis
The Cisco Nexus 5596UP chassis is 2 RU or 3.47 inches (8.8 cm) tall, 17.3 inches (43.9 cm) wide, and
29.5 inches (74.9 cm) deep. It is designed to be mounted in a standard 19-inch wide rack. The front of
the switch, shown in Figure 1-1, has a USB port, four Ethernet and ports (two cross-connect ports, one
management port, and one console port), two power supplies, and four fan modules.
