Features
The Cisco Nexus 5548UP switch is a 10-Gigabit Ethernet and FCoE switch that offers up to 960-Gbps
throughput and up to 48 ports. The switch has 32 fixed 1- or 10-Gbps SFP+ Ethernet and FCoE ports and
one expansion slot. The expansion slot supports GEMs that offer 16 10-Gigabit Ethernet ports, eight
10-Gigabit Ethernet ports and eight 10-Gigabit FCoE ports, or 16 10-Gigabit Ethernet/FCoE ports. This
switch has an orange label with “Cisco Nexus 5548UP” above the Cisco logo on the front of the chassis.
The Cisco Nexus 5548P switch is a 10-Gigabit Ethernet switch that offers up to 960-Gbps throughput
and up to 48 ports. The switch has 32 fixed 1- or 10-Gbps SFP+ Ethernet and FCoE ports and one
expansion slot. The expansion slot supports GEMs that offer 16 10-Gigabit Ethernet ports or eight
10-Gigabit Ethernet ports and eight 10-Gigabit FCoE ports. This switch has a gray label with “Cisco
Nexus 5548P” above the Cisco logo on the front of the chassis.
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 (port-side exhaust) cooling that supports efficient data center hot and cold-aisle
designs. The Cisco Nexus 5548UP alternatively supports back-to-front (port-side intake) cooling
(all fan and power supply modules in the same chassis must support the same direction of airflow).
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.
(For details, see the chapter, “Using the Device File Systems, Directories, and Files” in the
NX-OS
Fundamentals Configuration Guide
for your software release.)
Thirty-two fixed 10-Gigabit Ethernet ports and expansion modules are at the rear of the switch. The front
of the switch has an indicator LED, management ports, 2 fan modules and 2 power supplies as shown in
Figure 1-16
