Cisco NIB N55-M16UP Cisco Network Module

Product Specification

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 The N55-M160L3-V2 uses a newer version of the Layer 3 ASIC that enables higher table sizes in a future software release from 8K host entries to 16K host entries or from 4K multicast routes to 8K multicast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.

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 The N55-M160L3-V2 uses a newer version of the Layer 3 ASIC that enables higher table sizes in a future software release from 8K host entries to 16K host entries or from 4K multicast routes to 8K multicast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.

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.

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.

Figure 1-8 shows an AC power supply. For more information on the LEDs, see Table D-1.

Figure 1-11 NXA-PDC-1100W

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.
