Chapter 1 Overview
Cisco Nexus 5500 Platform Switches
Power Supply
The Cisco Nexus 5596T uses a front-end power supply. The chassis has slots for two power supplies.
The Cisco Nexus 5596T switch is fully functional with one power supply, but you can include a second
power supply for power redundancy.
Table 1-1
lists the power supplies that you can order with the Cisco Nexus 5596UP and 5596T switches.
Note
Front-to-Back (port-side exhaust) airflow and DC power supplies are now supported for the Cisco Nexus
5596T. For details see the
Cisco Nexus 5500 Datasheet.
Figure 1-8

Figure 1-9

, and
Figure 1-11
show the power supplies that can be ordered with
the Cisco Nexus 5596UP and 5596T switches. For more information on the LEDs, see
Table D-1 on
page D-2
.
Note
Never leave a power supply slot empty. If you remove a power supply, replace it with another one. If you
do not have a replacement power supply, leave the non functioning one in place until you can replace it.
Fan Module
The Cisco Nexus 5596T switch has four fan modules. Although the switch can function when a fan stops
functioning within a fan module, if a whole fan module stops functioning, you must replace the fan
module. The Cisco Nexus 5596T supports either front-to-back (port-side exhaust) or back-to-front
(port-side intake) airflow (all fan and power supply modules must support the same direction of airflow).
Transceivers
The Cisco Nexus 5596T switch supports both SFP and SFP+ Ethernet transceivers and SFP Fibre
Channel transceivers.

SFP+ Transceivers
The enhanced SFP+ 10-Gigabit Ethernet transceiver module is a bidirectional device with a transmitter
and receiver in the same physical package. It has a 20-pin connector on the electrical interface and
duplex LC connector on the optical interface.
