As a top-of-rack switch, all the servers in the rack connect to the Cisco Nexus 5548UP or Cisco Nexus
5548P switch, and it connects to the LAN or SAN.
The Cisco Nexus 5548UP and 5548P switches have the following features:
•One slot on the back of the switch for a Generic Expansion Module (GEM). Two slots on the front
of the switch for hot swap-capable power supplies.
•Two slots on the front of the switch for hot swap-capable fan modules. You can insert four fans per
module, which gives you a total of eight fans.
•One slot at the front of the switch for a USB port.
•Front-to-back cooling that supports efficient data center hot and cold-aisle designs.
Chassis
The Cisco Nexus 5548 switch chassis is 1 RU, 1.72 inches (4.4 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 (48.26 cm) rack. The
switch has two power supplies and two fans modules on the front of the switch. The switch also has one
USB port (usb1:) at the front of the switch. This external USB flash memory is installed in a supervisor
module used for storing image files, configuration files, and other miscellaneous files. You can create
directories on external flash memory and navigate through these directories. You can also create and
access files.
The usb1: port usage on the Cisco Nexus 5548 switch is the same as that on other Cisco NX-OS devices.
