◆“Data Center Deployment” on page 13
System Overview
The AS6700-32X / AS6701-32X switch is an high-capacity top-of-rack switch. It is
designed for data centers with extended bandwidth demands that require a dense
concentration of 40 Gigabit Ethernet (40G) links within a 1U footprint. The switch
provides 20 40G QSFP+ ports and two expansion slots that enable the addition of
two six-port 40G QSFP+ expansion modules. The switch also includes dual load-
sharing power supply units that are hot-swappable.
The switch includes models that run Edge-Core’s Data Center Switch Software
(DCSS) and those that use the Open Network Installer Environment (ONIE), which
supports the installation of compatible independent network operating system
(NOS) offerings.
The DCSS switch software supports a full set of Layer 2 switching, data center
bridging, and Layer 3 routing features. The switch can be deployed as a top-of-rack
(TOR) or distributed spine switch to form a network fabric that can reduce
infrastructure expenses and power consumption in the data center. This network
fabric can be used to interconnect tens of thousands of servers delivering cloud
computing services.
The switch further offers an option of front-to-back (F2B) or back-to-front (B2F)
airflow cooling for rack deployment with either blade servers or other switches,
allowing cool aisles to be maintained without creating “hot loops.”

Data Center Deployment
The switch is designed for high-availability data center environments with a high
40G port density and switching capacity. The switch includes redundant, hot-
swappable, load-sharing AC PSUs, and a hot-swappable multiple-fan fan trays
where the direction of the cooling airflow can be set to either port-to-power or
power-to-port options. Meeting the network scaling requirements of enterprise
and cloud data centers, the switch can be deployed as a top-of-rack switch or as
part of a distributed spine network, providing full line-rate switching at Layer 2 or
Layer 3 across all ports.
Figure 3: Cloud Data Center Deployment
In many data center configurations, Ethernet connections link servers and data
networks, and Fibre Channel connections link servers to storage networks. This
switch enables the creation of a converged network, which supersedes Fibre
Channel and employs lossless Ethernet connections between FCOE storage,
servers, and other data network switches.

Rack Cooling The top-of-rack switch is a high-performance, high-density unit that generates a
substantial amount of heat. When mounted in a rack with other equipment, it is
important that the switch has the same airflow direction to avoid “hot loops” in the
data center ailses. Hot loops increase cooling requirements since warm air is drawn
into rack devices instead of cool air.
Most rack-mounted blade servers draw cool air from the front and expel hot air at
the rear. The top-of-rack switch includes two fan trays that have a front-to-back
(F2B) airflow direction that maintains cool ailses in the data center.

When mounted in a rack with other network equipment that may have a back-to-
front (B2F) airflow direction, the top-of-rack switch includes two fan trays that
reverse the airflow direction through the switch. This enables flexible deployment
options for the switch in the data center.

General Installation Guidelines
– 17 –
General Installation Guidelines
Be sure to follow the guidelines below when choosing a location.
◆The installation location should:
■be able to maintain its temperature within 0 to 40 °C (32 to 104 °F) and its
humidity within 10% to 90%, non-condensing.
■provide adequate space (approximately five centimeters or two inches) on
all sides for proper air flow.
■be accessible for installing, cabling and maintaining the device.
■allow the status LEDs to be clearly visible.
◆Make sure twisted-pair cable is always routed away from power lines,
fluorescent lighting fixtures and other sources of electrical interference, such as
radios and transmitters.
◆Make sure that the unit is connected to a separate grounded power outlet and
is powered from an independent circuit breaker. As with any equipment, using
a filter or surge suppressor is recommended. Verify that the external power
requirements for the switch can be met as listed under “Power Supply Units” on
page 27.
Installation Precautions
Warning: This switch uses lasers to transmit signals over fiber optic cable. The
lasers are compliant with the requirements of a Class 1 Laser Product and are
inherently eye safe in normal operation. However, you should never look directly at
a transmit port when it is powered on.
Warning: When selecting a fiber QSFP+ device, considering safety, please make
sure that it can function at a temperature that is not less than the recommended
maximum operational temperature of the product. You must also use an approved
Laser Class 1 QSFP+ transceiver.
Caution: Before installing your switch, first review all the safety statements and
guidelines in the Regulatory and Safety Information document.
Caution: The switch includes plug-in fan trays that are installed into its chassis. All
installed fan trays must have a matching airflow direction. That is, all fan trays must
have a front-to-back (F2B) airflow direction, or all fan trays must have a back-to-
front (B2F) airflow direction. Each fan tray includes a label that indicates its airflow
direction.

Chapter 2 | Installation Overview
Switch Installation Tasks
– 18 –
Caution: Installing the switch in a rack requires two people: One should position
the switch in the rack, while the other secures it using the mounting screws.
Caution: The earth connection must not be removed unless all supply
connections have been disconnected.
Switch Installation Tasks
Follow these tasks to install the switch in your network. For full details on each task,
go to the relevant chapter or section by clicking on the reference link.
Note: The chapters in this guide are organized in the same sequence as the
installation tasks. For detiled installation procedures, it is recommended to read
chapters 3 through 6 in sequence.

Rack Mount Guidelines
When rack mounting the switch, pay particular attention to the following factors:
◆ Rack Types: You can use any standard EIA 19-inch equipment rack with either
two or four posts. The bracket hole pattern should be spaced 1U (1.75 in. or
4.45 cm) apart.
◆ Rack Stability: Whenever possible, secure the rack to the building ceiling or
floor, particularly if you are located in a region where earthquakes are common.
◆ Rack Planning: When installing equipment in a rack, first plan how units can
be best arranged. Try to always mount the heaviest equipment at the bottom
of the rack.
◆ Temperature: Since the temperature within a rack assembly may be higher
than the ambient room temperature, check that the rack-environment
temperature is within the specified operating temperature range. See “Switch
Cooling Requirements” on page 22.
◆ Mechanical Loading: Do not place any equipment on top of a rack-mounted
unit.
◆ Circuit Overloading: Be sure that the supply circuit to the rack assembly is
not overloaded.
◆ Grounding: Rack-mounted equipment should be properly grounded.

Chapter 3 | Switch Chassis
How to Install the Switch in a Rack
– 20 –
Rack Cooling When mounting the switch in an enclosed rack or cabinet, be sure to check the
following guidelines to prevent overheating:
◆Make sure that enough cool air can flow into the enclosure for the equipment it
contains.
◆Check that the rack or cabinet allows the hot air to exit the enclosure (normally
from the top) without circulating back into equipment.
◆If the enclosure has sides or doors with ventilation holes, make sure they are
not blocked by cables or other obstructions.
◆Route cables within the rack or cabinet to maximize the airflow.
◆When possible, do not completely fill the rack or cabinet with equipment, allow
some unused space within the enclosure for better airflow.
How to Install the Switch in a Rack
Before you start to rack-mount the switch, be sure to have the following items
available:
◆Four mounting screws for each device you plan to install in a rack—these are
not included. Be sure to use the rack mounting screws that are supplied with
the rack.
◆A screwdriver (Phillips or flathead, depending on the type of screws used).
To rack mount the switch, follow these steps:
Caution: Installing the switch in a rack requires two people: One should position
the switch in the rack, while the other secures it using the mounting screws.
1. Attach the brackets to the device using the screws provided in the Rack
Mounting Kit.
