CHAPTER
TWO
PRECAUTIONS FOR PRODUCT SERVICE AND USE
This section discusses considerations you must take before installing, using, or servicing FXT 5000 Series edge fil-
ers.
2.1 Unpacking and Handling FXT Equipment
To prevent damage to the edge filer or components, carefully unpack and handle the FXT Series edge filer and com-
ponents.
Inspect the boxes that the edge filer or component was shipped in and note whether there is any damage. If the ship-
ment shows evidence of damage, file a damage claim with the carrier that delivered it.
2.2 Restricted Access
The FXT Series edge filer nodes must be installed in a restricted-access location. A restricted-access location is de-
fined as a location that can be accessed only by use of a tool, lock and key, or other means of security and is con-
trolled by the authority responsible for the location. Anyone entering the restricted-access location, or installing or
replacing modules in an FXT Series node, must be trained in the potential hazards associated with the FXT Series
node, including but not limited to exposure to hazardous energy levels when the cover is removed, when modules
have been removed, or when modules are being replaced.
2.3 Preventing Condensation
Condensation can occur when exposing a colder product to a warmer and/or more humid environment.
If an item has been moved from an environment that is colder and less humid than the current installation and oper-
ating environment, allow it to reach the same temperature as the current environment before unpacking it, and before
installing it or powering it on.
If you notice condensation on any part of the item, Avere Systems recommends waiting a minimum of 24 hours for it
to acclimate before installation and use.

FXT 5000 Series Field Service Guide
2.4 Electrical Considerations
This section lists guidelines for safe electrical handling of the FXT Series edge filer node.
2.4.1 Electrical Code Compliance
To avoid the possibility of an electrical shock hazard, the electrical installation of an FXT Series edge filer and its as-
sociated rack(s) and power distribution units (PDUs) must comply with all applicable local, state, and national elec-
trical codes and regulations. Contact a qualified electrician if you are unsure about proper electrical installation.
2.4.2 Earth Grounding
• The building site, rack, and PDU electrical receptacles powering the FXT Series edge filer must be properly
grounded during the lifetime of the installation.
• The earth-ground connection for the rack must be designed and installed specifically for the rack, and must
not rely solely on unintentional grounding connections made through FXT Series nodes and other equipment
installed into the rack.
• The Avere FXT Series node has been approved for use only with TN-type earth grounding systems. It has not
been approved for use with IT-type earth grounding systems. Do not connect the node to any non-TN type of
earth grounding system.
• To avoid the possibility of an electrical shock hazard, the FXT Series edge filer must be properly connected to
earth ground during the lifetime of the installation. The edge filer receives its earth ground connection through
the AC power cords. To ensure the integrity of the ground connection, observe the following guidelines:
–Use only power cords with a grounding plug.
–Inspect the ground pins of each power cord before initial use.
–Never remove or disable the grounding pin on a power cord or use an adapter that might affect the in-
tegrity of the ground connection.
2.4.3 AC Mains Disconnect
• The AC power cords serve as AC mains disconnect for the FXT Series edge filer and therefore must remain
readily accessible during the lifetime of the installation.
• The FXT Series edge filer is provided with multiple power cords, and has a power-on/standby-type power
switch. This switch does not function as an AC mains disconnect. To disconnect all power for maintenance
or an electrical emergency, remove all power cords.
4 Chapter 2. Precautions for Product Service and Use

FXT 5000 Series Field Service Guide
2.4.4 Power Supply Replacement
The power supply units for FXT series nodes have detachable power cords. Disconnect the power cord at the power
supply unit before removing the power supply unit from the node. When installing a power supply unit, insert the
unit into the node before connecting the power cord.
When running on a single power supply unit, the node has an increased probability of losing all power as a result of
the single unit failing. Always replace a failed power supply unit as soon as possible after failure.
2.4.5 Hazardous Energy Levels
• To avoid potential injury, remove all chains, rings, watches, and other metal jewelry before performing main-
tenance on powered-on equipment. Burns and other injuries can be caused by the flow of current through a
metallic object if the metallic object comes in contact with powered circuits.
• When replacing externally accessible components while power is applied to the node, never reach into the
empty space created by the removed components, because hazardous energy levels may be present.
2.5 Racked FXT 5000 Series Nodes
To avoid the potential of serious injury and equipment damage, observe the following precautions before installing
nodes into racks or before removing them from racks:
• Ensure that the node’s weight is fully supported by two people at all times while it is being installed into or
removed from a rack.
• The rack installation must be designed to remain stable while supporting the full weight of the installed equip-
ment in its maximum extended position.
• Follow the rack manufacturer’s recommendations and use the appropriate load calculator if available when
designing and installing rack systems.
• Contact the rack manufacturer or an engineering consultant if you require assistance determining the stability
of the rack for its intended purpose.
• For single-rack installations, specify and install stability options such as ballast kits, bolt-down kits, and exten-
sible or permanent stabilizing mechanisms.
• In multiple-rack installations, specify and install a multirack tie-kit option. If the multirack tie kit is not suf-
ficient to guarantee stability, then install ballast kits, bolt-down kits, and extensible or permanent stabilizing
mechanisms.
• Unless the rack installation is designed otherwise, extend only one piece of equipment from the rack at a time.
• Install the first piece of equipment into the bottom of the rack, with future equipment installed above that.
2.5. Racked FXT 5000 Series Nodes 5

FXT 5000 Series Field Service Guide
• For installing multiple pieces of equipment at the same time, first install the heavier equipment at the bottom,
then install the lighter equipment sequentially above that.
• Rack-mounted equipment should not be used as a shelf, work space, step, or seat.
2.6 General Precautions
Observe the following precautions to prevent injury to yourself and damage to the FXT Series edge filer.
2.6.1 Service Area Clearance
To permit service personnel to perform maintenance procedures on the FXT Series edge filer, a minimum of 24
inches of clearance must be provided in front of and behind the immediate area being serviced.
2.6.2 California Perchlorate Warning
This product contains chemicals known to the State of California to cause cancer, birth defects or other reproductive
harm.
The following notice is provided in accordance with California Code of Regulations Title 22, Division 4.5, Chapter
33, Best Management Practices for Perchlorate Materials.
This product includes a lithium manganese dioxide battery that contains a perchlorate substance.
Perchlorate Material – special handling may apply. See www.dtsc.ca.gov/hazardouswaste/perchlorate.
2.6.3 Two-Person Lift
A bare node without accessories and outer rails weighs 33 pounds (15.0 kilograms). For ease of installation it is rec-
ommended to use two people to lift and install the node into the rack. When lifting a node, handle it in such a way
that the weight is evenly distributed and stabilized. Be sure to comply with any personal lifting limits that may be in
effect for your locale.
2.6.4 CMOS Battery Replacement
DANGER OF EXPLOSION IF BATTERY IS INCORRECTLY REPLACED. REPLACE ONLY WITH THE SAME
OR EQUIVALENT TYPE RECOMMENDED BY THE MANUFACTURER. DISPOSE OF USED BATTERIES
ACCORDING TO THE MANUFACTURER’S INSTRUCTIONS.
6 Chapter 2. Precautions for Product Service and Use

FXT 5000 Series Field Service Guide
ATTENTION: IL Y A DANGER D’EXPLOSION S’IL Y A REMPLACEMENT INCORRECT DE LA BATTERIE,
REMPLACER UNIQUEMENT AVEC UNE BATTERIE DU MÊME TYPE OU D’UN TYPE ÉQUIVALENT
RECOMMANDÉ PAR LE CONSTRUCTEUR. METTRE AU REBUT LES BATTERIES USAGÉES CONFOR-
MÉMENT AUX INSTRUCTIONS DU FABRICANT.
The motherboard battery maintains clock and CMOS settings when the node is without power for any reason. Con-
tact Avere Global Services if you suspect that the motherboard battery needs to be replaced.
2.7 Laser Radiation
CLASS 1 LASER PRODUCT
FXT Series nodes that contain optical networking ports may emit invisible laser radiation from those ports. When
no fiber-optic cable is connected, do not stare into the open apertures. In addition, install protective covers over any
optical ports that will not have a cable connected.
2.8 Thermal Considerations
• FXT Series nodes use front-to-back cooling airflow. If the FXT Series node is installed in a rack, the installer
is responsible for ensuring that adequate airflow is available through the rack to effectively cool the node.
• Environmental ambient temperature requirements apply to the area immediately around the node. For a node
installed into an enclosed rack or a rack with perforated doors, the ambient temperature requirement applies to
the area inside the rack or door, immediately around the node.
• Operating the FXT Series node in a rack with open EIA U spaces can cause unintended airflow paths and as-
sociated temperature inconsistencies. To maintain proper airflow and temperatures, cover all open rack spaces
with blank panels.
• Ensure that the node cover is in place when the node is operating to assure proper airflow and cooling. Ther-
mal damage to the system can occur if this practice is not strictly followed.
• Do not remove disk drives or power supply units unless a replacement component is immediately available.
If you remove a replaceable component, replace it before putting the unit back into service to ensure proper
airflow and cooling. Damage to the system can occur if this practice is not strictly followed.
2.9 Electrostatic Discharge (ESD) Precautions
An ESD event occurs when two objects with different electrical charges come into contact with each other. Elec-
tronic devices can be severely damaged by ESD.
When handling electronic modules such as disk drives, printed circuit boards (PCBs), and power supplies, observe
the following basic ESD precautions to prevent damage.
2.7. Laser Radiation 7

FXT 5000 Series Field Service Guide
• If possible, perform any maintenance at an approved ESD-safe workstation.
• Do not unpack or install electronic modules without using a properly grounded wrist or heel strap.
• Keep all electronic modules such as power supplies, PCBs, and disk drives in their original ESD-protective
packaging until you are ready to install them.
• Handle all electronic modules carefully. Do not touch connectors, contacts, or component leads.
• Ensure that electronic modules do not come into contact with insulators such as clothing and plastics.

FXT 5000 SERIES EDGE FILER OVERVIEW
The Avere FXT Edge Filer solution uses a cluster of network-attached storage (NAS) devices, called nodes, to in-
crease file operation performance between back-end storage (NAS devices or cloud storage) and clients.
Each node is a server that runs Avere OS software. Physical nodes in the FXT 5000 Series contain and use multiple
types of storage media.
If a part fails, any combination of the following will happen:
• An alert will appear on the Avere Control Panel software monitoring system
• An LED will light on the node chassis
• An audible alarm will sound from the node
For more information on alerts, refer to the Avere Control Panel Dashboard Guide
(http://library.averesystems.com/#operations).

3.2 Attaching a Console to an FXT 5000 Series Node
You will need to attach a console to the node’s serial port in certain situations, including these:
• The Avere Control Panel becomes unresponsive and SSH terminal access to the cluster or individual nodes
fails
• To monitor a node’s boot process after replacing both system drives
The serial port on the FXT 5000 Series node is configured as follows:
• Speed: 115200 baud
• Data bits: 8
• Stop bits: 1
• Parity: None
• Flow control: None
To attach the console:
1. Locate the serial (COM1) port on the rear of the node
2. Use a null modem cable to connect the COM1 serial port to a terminal configured for ANSI-115200-8N1.
3. Log in to the console.

3.4 Controls and LED Status Lights
This section gives details about the buttons and LED indicators on the FXT 5000 Series.
3.4.1 Control Panel Buttons
Each FXT 5000 Series node has two buttons, which appear on the front right control panel section.
Front Control Panel
Power Button
The power button can be used to turn the node on and off.
The power button should never be used to power off a system unless absolutely necessary. All system
shutdowns should be done from the Avere Control Panel interface so that the cluster can properly recon-
figure itself when restarting.
In some circumstances the user might have no other choice but to use the power button to power off a
node. In that case, follow this procedure:
1. Press and release the power button once, and wait. The system will attempt to perform an orderly
shutdown, which can take several minutes.
If you do not see evidence of the node shutting down within five minutes, try the next step.
2. If the node does not power down from the single button press, press and hold the power button for
at least 3 seconds. The system will shut down immediately.
Unit Identifier (UID) Button
Push the UID button on the front of the chassis to activate or deactivate the unit identifier LED.
