1 Qualified and Approved Switches for Avid
NEXIS
This document provides Avid NEXIS Administrators with a single reference regarding the
implementation, configuration and troubleshooting of Avid
capable Ethernet switches for use as the Avid Production Network (APN) switch for the following
Avid platforms:
• Avid NEXIS | PRO (1 x 10GbE)
• Avid NEXIS | E2 (2 x 10GbE per Controller)
• Av id NEXIS | E2 SSD (2 x 40GbE per Controller)
• Avid NEXIS | E4 (2 x 10GbE per Controller)
• Avid NEXIS | E5 (2 x 40GbE per Controller)
• Avid NEXIS | E5 NL (2 x 10GbE per Controller)
• Avid NEXIS | SDA (2 x 10GbE per Controller)
You cannot mix an Avid NEXIS | PRO in the same shared storage system as an Avid NEXIS E-Series
n
Engine or an Avid NEXIS | SDA.
Avid has the following designations for Ethernet switches that can provide suitable performance for
Avid NEXIS storage:
• Qualified
Fully qualified for a broad range of applic ations. Qualified sw itches are typically p art of the Avid
engineering and test labs and part of ongoing testing.
®
qualified, approved, and architecturally
•Approved
Approved for deployment as detailed in the Avid ISIS / NEXIS & Media Central Network
Requirements Document. (Approved switches are typically tested at a customer site as part of a
specific commissioning engagement.)
All of the listed switches support using the 802.3ad Link Aggregation Control Protocol (802.1ax),
which is supported on any Avid NEXIS E-Series Engine and the Avid NEXIS | SDA running Avid
NEXIS v7.0 or higher. The Avid NEXIS | PRO does not support using LACP.
Refer to the switch vendor’s documentation for specifics.
The switches in each table are listed in alphabetical order. If a switch cannot connect directly to an
Avid NEXIS system it can still be used as a down-linked (subordinate) edge switch.

Connecting the Engine to a Switch
To connect the Avid NEXIS to a switch, you will need one or two transceivers or direct attach
(T winax) cables per Controller (if using redundant Controllers), depending on whether you are using
link aggregation.
To connect the Storage Controller(s) to one or more switches:
1. Insert a supported transceiver module or cable into the left port on each Controller if not using
LACP, or both ports, if using LACP.
2. Insert the appropriate cables into the modules.
Connecting the Engine to a Switch
3. Connect the other end of the cables to the appropriate ports on your switch or switches.
Flow Control in Avid Production Networks
If you are experiencing poor read performance even when using tools like Avid PathDiag or Avid
Benchmark Utility, check the switch port to see if the client is sending a large number of Pause
frames. These are usually reported as “Throttles” in the input statistics for the interface on most
switches, but can also be reported as “802.3x Pause Frame s .”
If this occurs, check whether the switch port is configured to honor Rx Flow Control (make sure
FlowControl Rx is enabled). If not, en able Rx Flow Control and reset the port or client to see if the
issues persist. If they do, contact Avid.
Flow control is enabled by default on all the currently supported switches (except Dell S4048-ON).
Enabling Flow Control on the Dell S4048-ON
By default, Flow Control is disabled on the Dell N etworking switch S4048-ON . To use this switch in
an Av id NEXIS environment, you must enable Flow Control. Consult the Dell Networking switch
documentation for information on how to log into the switch, then enter these commands:
To enable Flow Control on the Dell S4048-ON:
1. S4048#configure
2. S4048(conf)#int range tengigabitethernet 1/1 - 1/48
3. S4048(conf-if-range-te-1/1-1/48)#flowcontrol rx on tx off
4. S4048(conf-if-range-te-1/1-1/48)#exit
5. S4048(conf)#int range fortyGigE 1/49 - 1/54

8. S4048(conf)#exit
9. S4048#exit
Configuring Switches for LACP
In Avid NEXIS v7.0 and higher, the Engines and Avid NEXIS | SDA support enabling LACP on the
Ethernet ports on the Controllers. See the A vid NEXIS Administration Guide for more information on
enabling LACP on the Controllers.
Configuring Switches for LACP
c
Before enabling LACP on the Engines or A vid NEXIS | SDA, make sur e both Ethernet ports on

Configuring LACP (MLAG) on a Dell Networking S4810 Switch
This procedure describes how to group links into port channels and use the port channel interface to
send and receive traffic from the Avid NEXIS. If the Engine or Avid NEXIS | SDA has two
Controllers, the ports on each Controller must be in a separa te port channel.
In this example, ports 0/28 and 0/34 are connected to the 10GbE ports on the Controller in th e Avid
NEXIS Engine.
To configure LACP (MLAG) on a Dell S4810:
1. Identify an unused port channel. (The Dell S4810 supports up to 128 port channels).

Network Considerations
Carefully plan for space, environmental, and power requirements for your Avid hardware. This
section contains topics related to setting up your Avid network environment.
Computer Names
A hostname must comply with RFC 952 and RFC 1123 standards. For example, you cannot use an
underscore in a hostname. For more information, see the Microsoft Knowledge Base article “Naming
Conventions in Active Directory for Computers, Domains, Sites, and OUs.”
Verify Entries on the DNS Server
Make sure that you correct any errors in DNS entries for name to IP resolution. The Avid network
can become sluggish and unstable if there are incorrect entries in the DNS server for any of the
computers in the Interplay environment. Symptoms include excessive CPU usage by the Interplay
Framework Lookup service and Interplay Diagnostics. The tree view in the Interplay Service
Configuration or Health Monitor may also fail to populate if there are incorrect DNS entries.
14
Network Considerations
Configure the DNS Server to Support Reverse Lookup
Make sure that the DNS server is configured to support Reverse Lookups. If not, Interplay
Framework cannot resolve IP addresses to host names. Symptoms include; tree views fail to populate
in the Interplay Service Configuration, Interplay Diagnostics, and Health Monitor.
Non-DNS Environments
In a non-DNS environment you must configure a host file on all systems, including Avid Low Res
Encode systems. This is necessary so that the Interplay Framework can list the systems in its client
applications such as the Interplay Service Configuration or Health Monitor.
Computers with Multiple Network Interfaces
Computers that have multiple network interfaces in use must be entered in DNS so that all
IP addresses have the same hostname.
If you have multiple network interfaces on a computer and one is not used, use the Device Manager
to disable the interface. Otherwise, the computer might have problems communicating with the
Interplay Framework. If multiple network interfaces are used, adjust the binding order and local
specific routes to ensure the intended operation. Use the Advance setting in the Network adapter
properties to change the priority order on the network interfaces.
Configuring an Avid Shared Storage System
On an Avid Production Network, to support client s that are not routed, you must configure a Layer 3
switch to route between subnetworks.
Know Where Your Subnets Are on the Network
Create a system diagram that identifies the subnets on your Avid network environment. Avid
recommends you use Classless Inter-Domain Routing (CIDR) IP ranges of contiguous addresses
instead of non-contiguous ranges VLAN 16, 17, 18, 19.
Time Synchronization
If you already have a system in place to maintain Time Sync on your network, you can continue to
use that system. Avid Interplay prov ides the Interplay Framework Time Synchron iza tio n servi ce to
perform the same task. Avid has created a detailed guide on synchronizin g many Avid products.
Search for “A Guide to Time Synchronisation for Avid Interplay Systems” posted on the Avid
Knowledge Base at www.avid.com/US/support.
The Avid Time Synch ronization Servi ce enables time synchr onization be tween dif ferent machines in
a workgroup. The Time Synchronization Service can operate in either Master mode or Slave mode.
In Master mode, the service retrieves a reference time from a configured time source and
redistributes it to the Slave services within the workgroup. The time source c an be the local PC c lock,
an NTP server, or a timecode card installed in a server, such as the CaptureManager server. In Slave
mode, the Time Synchronization Service listens for time notifications from the workgroup and
(optionally) sets the local PC clock to match.
15
Network Considerations
It is important to use only one time synchronism mechanism to set the local PC clocks in the
Interplay environment. If a Time Synchronization Slave service is configured to set the local PC
clock and it detects that some other mechanism (such as Windows 32 Time Services) changes the
local clock, then the T ime Syn c Slave service will disable itself to avoid the local clock fro m jumping
back and forth. The Time Sy nc slave will also post a Warning in the Health Monitor.

The maximum length for optical Ethernet cables is limited by the core diameter (measured in
microns) and modal bandwidth (in units of MHz*km).
Avid supports multi-mode fiber (MMF) cable using 850 nm transceivers (1000BASE-SX short
distances). For specifications see the ISO 11801 structured cabling document.
Avid supports single-mode fiber cable using 1310 nm transceivers (long distances)
When connecting to the 10 Gb port, make sure that:
c
– The cable has the required modal bandwidth for the distance of the run.
– All multimode cables between a switch port and the other end of the cable run are
of the same diameter (for example, 50/125 um or 62.5/125 um).
Single mode transceivers are a Class 1 laser product per IEC 60825-1 Amendment
w
2(2001) and IEC 60825-2 1997. Operating this product in a manner inconsistent
with intended usage and specification may result in hazardous radiation exposure.

4 Requirements
The Avid hardware components are fully rack-mountable. They are comp atible with an y standa rd 19inch video racks using either NEMA or EIA mounting-hole layouts.
Electrical Requirements
Consider installing a separately derived power system for your Avid shared storage hardware. This
ensures that you can control the hardware grounding, with all grounds brought to a single point, and
that uncontrolled equipment, such as coffee makers or floor polishers, cannot be plugged into the
same power source as the Avid shared storage hardware.
If you do not create a separately derived power system, make sure the power outlets are from the
same distribution panel. This helps prevent the occurrence of ground loops that can be caused by
plugging equipment into power sources wi th different ground potentials.
If you run more than one power line because you have more than one UPS, make sure the power
lines come from the same distribution panel.
w
n
Have all the electrical work at your site done by a licensed electrician. All the electrical changes
must meet country, state, and local electrical codes.
As you choose the location for your Avid shared storage hardware, keep these electrical requirements
in mind:
• Make sure there is adequate, dedicated power for the UPSs that are part of your Avid shared
storage workgroup.
Avid recommends the use of UPSs, appropriately sized for your Avid shared storage workgroup, or
conditioned power in your computer room environment. This provides protection against sudden
power surges or losses that could cause you to lose files or experience data corruption.
• Make sure your location is away from major electrical equipment such as motors, air
conditioners, or elevators.
• Make sure the location is not subject to electrostatic buildup.
• Plug only your Avid hardware into the power strips. Do not plug i n cof fee make rs, radios, li ghts,
or other non-Avid devices.
The following table shows the electrical speci ficat ions for the Avid qualifie d and approv ed switches.
Make sure your site meets these specifications.
Environmental Requirements
The Avid NEXIS and Interplay hardware and switches are intended for use computer-room
environments. They are not intended for use on top of desks or in open of fic e envi ron ment s. When
you select a location, make sure that the location meets the following requirements:
• A sturdy, level floor, not subject to vibration.
• Away from high-traffic areas.
• Clean and free from dust, smoke, or other airborne contaminants.
• No significant temperature changes. Choose a location where the temperature doe s not vary
more than 18°F (7.78°C) per hour.
• No significant humidity changes. A location with approximately 40 percent humidity can
prevent problems stemming from electrostatic discharge.
• Adequate space in front of and behind the rack. You must be able to connect cables and service
parts of your hardware. It also needs adequate airflow for cooling.
