Warning Before you install, operate, or service the system, read the Site Preparation and Safety Guide. This guide contains important safety information you should know before working with the system.


Read Safety Notices

Read the following safety notices before installing the SN 5420 storage router.


Warning Ultimate disposal of this product should be handled according to all national laws and regulations



Warning The device is designed to work with TN power systems.



Warning Only trained and qualified personnel should be allowed to install or replace this equipment.



Warning Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord.



Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected.



Warning The plug-socket combination must be accessible at all times because it serves as the main disconnecting device.



Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 10A international) is used on the phase conductors (all current-carrying conductors).



Warning When installing the unit, the ground connection must always be made first and disconnected last.



Warning This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use.



Warning Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.



Warning During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself.



Warning The safety cover is an integral part of the product. Do not operate the unit without the safety cover installed. Operating the unit without the cover in place will invalidate the safety approvals and pose a risk of fire and electrical hazards.



Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place.



Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals.



Warning A voltage mismatch can cause equipment damage and may pose a fire hazard. If the voltage indicated on the label is different from the power outlet voltage, do not connect the chassis to that receptacle.



Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables.



Warning Class 1 laser product.



Warning Because invisible laser radiation may be emitted from the aperture of the port when no cable is connected, avoid exposure to laser radiation and do not stare into open apertures.


Site Planning

Planning the proper location and layout of your equipment rack or wiring closet is essential for successful storage router operation. Equipment placed too close together or in an inadequately ventilated area can cause system overtemperature conditions. In addition, poor equipment placement can make system panels inaccessible and difficult to maintain.

To ensure normal operation and avoid unnecessary maintenance, plan your site configuration and prepare your site before installation.

Table A-1 lists the operating and nonoperating environmental site requirements for the storage router. Within specified environmental ranges the system can continue to operate; however, a measurement that approaches the minimum or maximum of a range indicates a potential problem. You can maintain normal operation by anticipating and correcting environmental conditions before they exceed the maximum operating range.

Verify the site power for the type of device you are installing. Power requirements are useful for planning the power distribution system needed to support the storage router. Heat dissipation is an important consideration for sizing the air-conditioning requirements for an installation. See Table A-1 for power and heat ratings for the storage router.


Caution To prevent a loss of input power, verify that the total maximum load on the circuit supplying power to the power supply is within the current ratings of the wiring and breakers.

Installing Chassis Feet

This section explains how to install the chassis feet. The chassis feet are rubber push-rivet feet that are pressed into rivet holes on the bottom of the storage router chassis. If you want to rack-mount the chassis, skip this section and proceed to the next section, "Rack-Mounting the SN 5420 Storage Router".

Before placing the storage router on a desktop, shelf, or other flat, secure surface, follow these steps to install the rubber feet:


Step 1 Locate the four push-rivet rubber feet that were shipped with the chassis. (See Figure 2-1.)

Figure 2-1 Identifying Push-Rivet Rubber Feet

Step 2 Place the storage router upside down on a smooth, flat surface.

Step 3 Position a push-rivet rubber foot over one of the rivet holes and insert the rivet bottom into the hole. (See Figure 2-2). Press down on the rivet head until the rivet snaps into the hole. Repeat this step to install the remaining three feet.
