• Transceivers

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.

Figure 1-1 Front View of the Cisco Nexus 5596UP Switch

The management and console ports are in a 2 x 2 stacked RJ-45 jack. Figure 1-2 shows a close-up view of these ports. For information about the connector port LEDs, see Table D-1.

Figure 1-2 Management and Console Ports

The rear of the Cisco Nexus 5596UP chassis, shown in Figure 1-3, has 48 fixed 10-Gigabit Ethernet data ports on the bottom and three slots for optional expansion modules on top.

Figure 1-3 Rear View of the Cisco Nexus 5596UP Switch

Note The L1/L2/Mgmt1 ports are not usable. They are disabled at this time.

Expansion Modules

Expansion modules allow the Cisco Nexus 5596UP switch to be configured as cost-effective 10-Gigabit Ethernet switches and as I/O consolidation platforms with native Fibre Channel connectivity.

The Cisco Nexus 5596UP switch has three slots that can be used for the following optional expansion modules:

• 4-port QSFP expansion module
• 16-port Universal (Fibre Channel and Ethernet) GEM (N55-M16UP) that provides 8-, 4-, 2-, or 1-Gbps Fibre Channel and 1- or 10-Gigabit Ethernet ports
• Layer 3 GEMs (N55-M160L3 and N55-M160L3-V2) provide 160 Gbps of Layer 3 services. The N55-M160L3-V2 uses a newer version of the Layer 3 ASIC that enables higher table sizes in a future software release from 8K host entries to 16K host entries or from 4K multicast routes to 8K multicast routes (IPv4).

You can hot swap the expansion modules during operations, except the Layer 3 GEMs. You must power down the switch before you can insert or remove the Layer 3 GEMs.

This section includes the following topics:

• 4-port QSFP+ GEM
• 16-port Universal GEM2
• Layer 3 GEM

4-port QSFP+ GEM

The QSFP+ GEM (N55-M4Q), shown in Figure 1-4, is a generic expansion module (GEM) that provides 16x10 Gigabit Ethernet SFP+ in a 4 x QSFP+ form factor. This module is a field-replaceable unit (FRU) that you can hot swap during operations.

Figure 1-4 4-Port QSFP+ GEM

16-port Universal GEM2

The 16-port Universal GEM2, shown in Figure 1-5, has 16 8-, 4-, 2-, or 1-Gbps Fibre Channel or 1- and 10-Gigabit Ethernet ports. This module is a field-replaceable unit (FRU) that you can hot swap during operations.

Figure 1-5 16-Port Universal GEM2

See Figure 1-7 to see how ports are grouped and numbered on the Fibre Channel plus Ethernet expansion module.

Layer 3 GEM

The Layer 3 GEMs (N55-M160L3 and N55-M160L3-V2), shown in Figure 1-6, provide 160 Gbps of Layer 3 services. The expansion modules are field-replaceable units (FRUs). The N55-M160L3-V2 uses a newer version of the Layer 3 ASIC that enables higher table sizes in a future software release from 8K host entries to 16K host entries or from 4K multicast routes to 8K multicast routes (IPv4).

The Layer 3 GEMs are not hot swappable and can be inserted and removed only when the switch is powered down.

Note When a Layer 3 I/O module is inserted into a Cisco Nexus 5500 Series switch that does not have any other I/O modules, you cannot use port-channel numbers 127 and 128 as these port-channel numbers are used by the switch for internal communication. However, if port-channel numbers 127 and 128 have already been used before a Layer 3 I/O module is inserted into the switch, new port-channel numbers will be used by the switch for internal communication.

Figure 1-6 Layer 3 GEM2

Ports

Each port on the Cisco Nexus 5596UP switch is numbered, and groups of ports are numbered based on their function. The ports are numbered top to bottom and left to right. The 48 fixed ports support 8-, 4-, 2-, or 1-Gbps Fibre Channel transceivers and 1- or 10-Gigabit Ethernet transceivers.

Figure 1-7 shows how ports are numbered and grouped by function for both the fixed ports and the Fibre Channel plus Ethernet expansion module ports.

Figure 1-7 Port Numbering of Fixed Ports and Fibre Channel Plus Ethernet Expansion Module Ports

Power Supply

The Cisco Nexus 5596UP uses a front-end power supply. The chassis has slots for two power supplies. The Cisco Nexus 5596UP 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 (FAF) Airflow and DC Power Supply is now supported for the Cisco Nexus 5596T. For details see the Cisco Nexus 5500 Datasheet.

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 5596UP 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 5596UP supports the reverse air flow fan tray (N5596UP-FAN-B).

Figure 1-12 shows a fan module.

Caution All of the power supply and fan modules in the same chassis must use the same airflow direction or an error will occur with possible over heating and shut down of the switch. If you power up the switch with more than one airflow direction, you must power down the switch and replace the modules with the wrong airflow direction (modules not taking in coolant air from the cold aisle) before powering up the switch.

The Cisco Nexus 5548 switch supports the multimode 850-nm, 4-Gbps SFPs with 150-m reach (see Table 1-6 ).

Cables

On the Cisco Nexus 5500 Platforms, you can use an innovative Twinax copper cable that connects to standard SFP+ connectors for in-rack use and on the optical cable for longer cable runs.

For in-rack or adjacent-rack cabling, the Cisco Nexus 5500 Platform supports SFP+ direct-attach 10-Gigabit Ethernet copper, which integrates transceivers with Twinax cables into an energy efficient, low-cost, and low-latency solution. SFP+ direct-attach 10-Gigabit Twinax copper cables use only 0.1 W of power per transceiver and introduce only approximately 0.25 microsecond of latency per link.

For longer cable runs, the Cisco Nexus 5500 Platform supports multimode, short-reach optical SFP+ transceivers. These optical transceivers use approximately 1 W per transceiver and have a latency of less than 0.1 microsecond.

Table 1-7 shows details of the cables supported.
