Cisco Nexus 6001 Switch

This section describes the Cisco Nexus 6001 switches (N6K-C6001-64P and N6K-C6001-64T) and their components. This section includes the following topics:

Features

The Cisco Nexus 6001 Switch is a compact 1RU (1 Rack Unit), high-performance, low-latency 10/40-Gigabit Ethernet and Fibre Channel over Ethernet (FCoE) switch. It runs the industry-leading Cisco NX-OS Software operating system, providing features and capabilities that are widely deployed. There are two versions of the device, a Small Form-Factor Pluggable (SFP+) version (N6K-C6001-64P) and a 10G BASE-T (N6K-C6001-64T) version.

The Cisco Nexus 6001 switch has the following features:

  • 48 fixed SFP+ ports on the back of the switch.
  • Four Quad Small Form-Factor Pluggable (QSFP+) ports on the back of the switch.
  • Two slots on the front of the switch for hot swap-capable power supplies, which provide front-to-back and back-to-front airflow for cooling.
  • Three slots on the front of the switch for hot swap-capable fan modules.
  • A management and console interface on the front of the switch.

Chassis

The Cisco Nexus 6001 switch chassis is 1 RU, 1.75 inches (4.4 cm) tall, 17.3 inches (43.9 cm) wide, and 30 inches (76.2 cm) deep. The front of the switch is shown in Figure 1-1.

Power Supply

The Cisco Nexus 6001 switch uses a front-end power supply. The chassis has slots for two redundant power supplies. Power Supply options need to be configured with the base chassis. It needs minimum of one power supply to operate. OIR is supported on the power supplies and the power supplies are hot swappable. The Cisco Nexus 6001 supports front-to-back (port-side exhaust) and back-to-front airflow (port-side intake). Table 1-1 lists the power supplies that you can order with a Cisco Nexus 6001 switch.

Note The Cisco Nexus 6001 AC power supplies support both 110 and 220-volt (V) inputs.



Caution 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 Modules

The Cisco Nexus 6001 has three individual fan modules supporting four fans per module. Fan modules are hot-swappable. Fan modules operate in a 3+1 redundancy mode. If a fan fails, the unit can run indefinitely with only 3 operational fans. Fan options need to be configured with the base chassis. The Cisco Nexus 6001 switch supports front-to-back and back-to-front airflow.OIR is supported on the fan tray. Table 1-2 lists the fans that you can order with a Cisco Nexus 6001 switch.

Cisco Nexus 6004 Switch

This section describes the Cisco Nexus 6004 Switches (N6K-C6004-96Q and N6004-B-24Q) and their components. This section includes the following topics:

Features

The Cisco Nexus 6004 offers the industry’s highest 10 and 40 Gigabit Ethernet and Fibre Channel over Ethernet (FCoE) port density in a compact energy-efficient form factor, with integrated Layer 2 and Layer 3 features at wire speed and low latency of approximately 1 microsecond for any packet size. With a choice of front-to-back or back-to-front airflow options, the switch is designed for a broad range of traditional data center and large-scale virtualized cloud deployments. The Cisco Nexus 6004 switches are 4RU switches. The N6K-C6004-96Q is a 96-port,10/40-Gigabit Ethernet and Fibre Channel over Ethernet (FCoE) switch and has the following features:

  • 48 fixed ports on the back of the switch
  • Four slots on the back of the switch for expansion modules.
  • Six slots on the front of the switch for hot swap-capable power supplies, which provide front-to-back and back-to-front airflow for cooling
  • Four slots on the front of the switch for hot swap-capable fan modules.
  • One console management port on the front of the switch.
  • One USB port on the front of the switch.

The Cisco Nexus 6004 Extensible Fixed (EF) version (N6004-B-24Q) offers eight line-card expansion module (LEM) slots to support a total of 96 ports of 40 Gbps throughput in a fully populated system. It provides low-cost entry point for small-scale deployments. Each LEM supports 12 ports of 40 Gigabit Ethernet in a QSFP form factor. Each 40 Gigabit Ethernet port can also be split into four line-rate 10 Gigabit Ethernet ports using QSFP breakout cables. this Cisco Nexus 6004 chassis along with the LEMs offers incredible flexibility for scaling deployments, making it the only fully extensible fixed 10 and 40 Gigabit Ethernet platform in the industry.

Chassis

The Cisco Nexus 6004 switch chassis is 4 RU, 6.97 inches (17.7 cm) tall, 17.3 inches (43.9 cm) wide, and 30 inches (76.2 cm) deep.

It is designed to be mounted in a standard 19-inch wide rack. The front of the switch, shown in Figure 1-3, has a console management port and USB port, six power supplies, and four fan modules.

Expansion Modules

Expansion modules allow the Cisco Nexus 6004 switch to be configured as a cost-effective 10/40/100-Gigabit Ethernet switch and as an I/O consolidation platform with native Fibre Channel connectivity.

The Cisco Nexus 6004EF switch has eight slots, and the Cisco Nexus 6004 switch has four slots, that can be used for the following expansion modules:

  • N6K-C6004-M12Q: Hot swappable linecard expansion module (LEM) that provides 12x 40-Gigabit Ethernet/FCoE QSFP ports.
  • N6004X-M20UP: Hot swappable LEM that provides 20x 1/10-Gigabit Ethernet/FCoE SFP+ and 8/4/2-Gigabit Fibre Channel ports for the Cisco Nexus 6004EF switch.
  • N5696-M4C: Hot swappable LEM that provides 4x 100-Gigabit Ethernet ports for the Cisco Nexus 6004EF switch.

You can hot swap the expansion modules during operations.


Caution You must power off the module before removing the module from the system for hot swap.

Figure 1-6 shows the N6K-C6004-M12Q expansion module.

Figure 1-6 12 Port 40 Gbps Linecard Expansion Module

 

N6004X-M20UP

The Unified Port LEM (N6004X-M20UP) for the Cisco Nexus 6004EF switch provides up to twenty 1/10 Gigabit Ethernet and FCoE ports using the SFP+ interface or up to twenty ports of native Fibre Channel connectivity using 8/4/2-Gbps SFP+ and SFP interfaces. The use of 1/10 Gigabit Ethernet or 8/4/2-Gbps Fibre Channel on a port is mutually exclusive but can be selected for any of the twenty physical ports per module.


Note The Cisco Nexus N6004X-M20UP LEM requires NX-OS Release 7.0(1)N1(1) or later.


N5696-M4C

The Cisco Nexus 5696-M4C LEM is a 4-port 100G LEM that provides 100 Gigabit Ethernet ports for the Cisco Nexus 6004EF switch. Each 5696-M4C offers 4 CXP optical module connections, which provide a total bandwidth of 400Gbps. The port interface supports CXP optical PMD modules such as CXP-100G-SR10 and CXP-100G-SR12. You can configure a total of 8 100G LEM modules in a Cisco Nexus 6004EF switch to provide a total of 32 CXP 100 Gigabit Ethernet connections.

Note The Cisco Nexus 5696-M4C LEM requires a minimum of 4 operating power supplies when installed.



Note The Cisco Nexus 5696-M4C LEM requires NX-OS Release 7.1(0)N1(1b) or later, and BIOS version 2.8.0 or later (included in the NX-OS release).


Ports

All the individual ports on the Cisco Nexus 6004 switch are numbered and groups of ports are numbered based on their function. Depending on how it is configured, there are 96 ports on the Cisco Nexus 6004 switch. The ports are numbered from top-to-bottom and from left-to-right. The fixed ports are grouped together and the modular ports are grouped together.

For the M4C LEM, port 1 and 2 are on the left and port 3 and 4 are on the right.

Figure 1-8 shows how ports are numbered and grouped by function.

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 6004 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 6004 switch supports the front to back airflow (N6K-C6004-FAN-F) and back to front airflow (N6K-C6004-FAN-B).

Figure 1-10 shows a fan module.

The bicolor status LED indicates fan tray health. Green indicates normal operation, while amber indicates a fan failure. For more information about LEDs, see Table D-1 .


Caution You must order all fan modules and power supplies in the same chassis so that they have the same direction of airflow with coolant air entering the chassis from the cold aisle and exhausting to the hot aisle.

Airflow

Power supplies and fan modules should be selected depending on the desired air flow direction.
