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 loadsharing 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.”

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.

Switch Cooling Requirements
Wherever the switch is located, be sure to pay close attention to switch cooling
requirements. The location should be well ventilated and provide unrestricted air
flow at the front, back, and sides of the switch. If the air flow is insufficient, it may
cause the switch to overheat and possibly fail.
The switch includes five removable fan trays located in the rear of the switch. The
fan tray options may have either a front-to-back (F2B) airflow direction or a back-tofront (B2F) airflow direction. For proper switch cooling, all installed fan trays must
have a matching airflow direction.
The following figure shows the airflow through the switch.

Switch Cooling Requirements
| Switch Chassis
Fan Trays The fan trays are an important part of the switch air cooling system. Five fan trays
must be installed in the switch at all times. If a fan should fail, the fan tray must be
replaced as soon as possible.
The fan trays installed must have a matching airflow direction. You must only
install fan trays that are either all front-to-back airflow or back-to-front airflow:
◆ ES6622BTS-FANTRAY (front-to-back airflow)
◆ ES6622BTSR-FANTRAY (back-to-front airflow)
The airflow direction of the fan tray is indicated by labels attached to the fan tray
(see Figure 10 on page 23).
Caution:
All installed fan trays must have a matching airflow direction. Installing a
front-to-back (F2B) tray with a back-to-front (B2F) fan tray may result in overheating
and subsequent damage to the switch.
Each of the removable fan trays, located at the rear of the switch, include dual inline fans and support fan speed control. The fan speed is dynamically controlled as
a function of temperature: the higher the internal temperature, the faster the speed
of the fans. The fan trays do not include LED indicators.
The following figure shows a fan tray being installed into the switch.

Power Supply Units
The switch supports hot-swappable power supply units (PSUs). You can install up
to two PSUs with matching airflow direction in the switch. The PSUs operate in a
load-sharing mode and provide 1+1 redundancy.
Note:
1+1 redundancy is a system where a switch power supply is backed up by
another switch power supply in a load-sharing mode. If one power supply fails, the
other power supply takes over the full load of the switch.
The AC Power Supply Units require power from an external AC power supply that
can meet the requirements as listed in Table 3. A standard AC power socket is
located on the rear panel of the PSU. The power socket is for the AC power cord.

Management Overview
Switch models that run Edge-Core’s DCSS software have it pre-loaded on the
switch. Switch models that use the Open Network Installer Environment (ONIE)
have the software installer pre-loaded on the switch, but no switch software image.
The user should refer to network operating system (NOS) installer and NOS
documentation for details on available options and set up for ONIE.
The DCSS switch models include a management agent that allows you to configure
or monitor the switch using its embedded management software. To manage the
switch, you can make a direct connection to the console port (out-of-band), or you
can manage it through a network connection (in-band) using Telnet, Secure Shell
(SSH), a web browser, or SNMP-based network management software.
The switch’s Management port (RJ-45) provides a dedicated management channel
that operates outside of the data transport network. This makes it possible to
reconfigure or troubleshoot the switch over either a local or remote connection to
the Management port when access through the data channel is not possible or
deemed insecure.
For a detailed description of the switch’s DCSS software features, refer to the
Administrator’s Guide.

Cable Labeling and Connection Records
When planning a network installation, it is essential to label the opposing ends of
cables and to record where each cable is connected. Doing so will enable you to
easily locate inter-connected devices, isolate faults and change your topology
without need for unnecessary time consumption.
To effectively manage a network’s physical deployment, follow these guidelines:
◆ Clearly label the opposing ends of each cable.
◆ Using your building’s floor plans, draw a map of the location of all network-
connected equipment. For each piece of equipment, identify the devices to
which it is connected.
◆ Note the length of each cable and the maximum cable length supported by the
switch ports.
◆ For ease of understanding, use a location-based key when assigning prefixes to
your cable labeling.
◆ Use sequential numbers for cables that originate from the same equipment.
◆ Differentiate between racks by naming accordingly.
– 41 –

Copper Cabling Guidelines
| Port Connections
◆ Label each separate piece of equipment.
◆ Display a copy of your equipment map, including keys to all abbreviations at
each equipment rack.
Copper Cabling Guidelines
The RJ-45 management port on the switch supports automatic MDI/MDI-X pinout
configuration, so you can use standard straight-through twisted-pair cables to
connect to any other network device (PCs, servers, switches, routers, or hubs).
The connection requires an unshielded twisted-pair (UTP) or shielded twisted-pair
(STP) cable with RJ-45 connectors at both ends.

10BASE-T
Category 3 or better 100-ohm UTP 100 m (328 ft) RJ-45
To ensure proper operation when installing the switch into a network, make sure
that the current cables are suitable for 10BASE-T, 100BASE-TX, or 1000BASE-T
operation. Check the following criteria against the current installation of your
network:
◆ Cable type: Unshielded twisted pair (UTP) or shielded twisted pair (STP) cables
with RJ-45 connectors; Category 5, 5e or better cable for 1000BASE-T
connections, Category 5 or better for 100BASE-TX connections, and Category 3
or better for 10BASE-T connections.
◆ Protection from radio frequency interference emissions
◆ Electrical surge suppression
◆ Separation of electrical wires (switch related or other) and electromagnetic
fields from data based network wiring
◆ Safe connections with no damaged cables, connectors or shields

1000BASE-T Cable Requirements
All Category 5 UTP cables that are used for 100BASE-TX connections should also
work for 1000BASE-T, providing that all four wire pairs are connected. However, it is
recommended that for all critical connections, or any new cable installations,
Category 5e (enhanced Category 5) or Category 6 cable should be used. The
Category 5e and 6 specifications include test parameters that are only
recommendations for Category 5. Therefore, the first step in preparing existing
Category 5 cabling for running 1000BASE-T is a simple test of the cable installation
to be sure that it complies with the IEEE 802.3-2008 standards.
Fiber Cabling Guidelines
The switch includes 20 slots for 40G QSFP+ fiber-optic transceivers.
Note that all 40GBASE fiber optic ports can operate in a single-lane mode at
40 Gbps full duplex, or in a four-lane mode at 10 Gbps full duplex.

How to Connect to QSFP+ Fiber Optic Ports
| Port Connections
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.
1. Remove and keep the port’s protective cover. When not connected to a fiber
cable, the cover should be replaced to protect the optics.
2. Check that the fiber terminators are clean. You can clean the cable plugs by
wiping them gently with a clean tissue or cotton ball moistened with a little
ethanol. Dirty fiber terminators on fiber cables will impair the quality of the
light transmitted through the cable and lead to degraded performance on the
port.
3. Connect one end of the cable to the QSFP+ port on the switch and the other
end to the QSFP+ port on the other device. Since QSFP+ connectors are keyed,
the cable can only be attached in the correct orientation.

4. As a connection is made, check the Link LED on the switch to be sure that the
connection is valid.
Direct Attach Cable (DAC) is a method of connecting SFP+/QSFP+ interfaces
without using optics and fiber cable. A fixed length of twinax copper cable is
terminated at each end with physically-compliant SFP+/QSFP+ transceivers that do
not include all their normal electronic and optical components. The result is a low
cost, low-latency, 10/40G Ethernet solution for short distances, ideal for
connections within the data center.
A 40G DAC connection is also known as twinax copper or 10GBASE-CR4. DAC
copper cables are available in pre-terminated fixed lengths up to 7 m (22.9 ft).
When operating in four-lane mode, a 40G QSFP+ port can also connect to four 10G
SFP+ ports using a DAC breakout cable.

A Troubleshooting
Diagnosing LED Indicators
Table 16: Troubleshooting Chart
Symptom Action
Sys LED is Off
Alarm LED is flashing Red
Port Link LED is Off
PSU LED is on Red
Fan Tray LED is on Red
◆
Check connections between the PSUs, the power cord, and the wall
outlet.
◆
Check if the PSU LED is on red. If required, replace the PSU.
◆
Contact your dealer for assistance.
◆
Check for a fan tray failure. If required, replace any fan tray as soon
as possible.
◆
Check for a PSU failure. If required, replace the PSU as soon as
possible.
◆
Power cycle the switch to try and clear the condition.
◆
If the condition does not clear, contact your dealer for assistance.
◆
Verify that the switch and attached device are powered on.
◆
Be sure the cable is plugged into both the switch and
corresponding device.
◆
Verify that the proper cable type is used and its length does not
exceed specified limits.
◆
Check the attached device and cable connections for possible
defects. Replace the defective cable if necessary.
◆
Replace the PSU as soon as possible.
◆
Replace the fan tray as soon as possible.
System Self-Diagnostic Test Failure
If the Sys LED indicates a failure of the system power-on-self-test (POST), you can
use a console connection to view the POST results. The POST results may indicate a
failed component or help troubleshoot the problem. For more information on
connecting to the console port and using the CLI, refer to the Administrator’s Guide.
Note a POST failure normally indicates a serious hardware fault that cannot be
rectified or worked around. If you encounter a POST failure, you should contact
your dealer for assistance.

Power and Cooling Problems
If a power indicator does not turn on when the power cord is plugged in, you may
have a problem with the power outlet, power cord, or PSU. However, if the switch
powers off after running for a while, check for loose power connections, power
losses or surges at the power outlet. If you still cannot isolate the problem, the PSU
may be defective.
Installation
Verify that all system components have been properly installed. If one or more
components appear to be malfunctioning (such as the power cord or network
cabling), test them in an alternate environment where you are sure that all the
other components are functioning properly.

In-Band Access
You can access the management agent in the switch through a connection to any
port using Telnet, a web browser, or other network management software tools.
However, you must first configure the switch with a valid IP address, subnet mask,
and default gateway. If you have trouble establishing a link to the management
agent, check to see if you have a valid network connection. Then verify that you
entered the correct IP address. Also, be sure the switch port has not been disabled.
If it has not been disabled, then check the network cabling that runs between your
remote location and the switch.
Note:
It is recommended that you use the out-of-band Management port as
described in the section:“How to Connect to the Mgmt Port” on page 39.
