1Installation
This section describes how to install and configure for first-time use:
• The QLogic 12000 switches in a network environment.
Planning the Installation
The 12000 is designed to be installed in an existing 19-inch equipment rack or
server rack.
NOTE:
These switches are designed for a four-post server cabinet. Do not mount in
a two-post telco cabinet.
Racks should conform to conventional standards. Use the American National
Standards Institute (ANSI)/Electronic Industries Association (EIA) standard
ANSI/EIA-310-D-92 and International Electrotechnical Commission (IEC) 297
Racks should meet the following mechanical recommendations:
• Four-post, 19" rack to facilitate easy maintenance
• Universal mounting rail hole pattern identified in IEC Standard 297
• Mounting holes flush with the rails to accommodate the chassis
NOTE:
Operation is subject to the following conditions:
Use a rack grounding kit and a ground conductor that is carried back to earth or to
another suitable building ground. Ground the equipment rack to earth ground.
Provide enough room to work on the equipment. Clear the work site of any
unnecessary materials. Make sure the equipment will have enough clearance for
front and rear access.

Cable Requirements
Cable Distances
When planning the location of the switches, consider the distance limitations for
signaling, EMI, and connector compatibility. It is recommended that the user does
not exceed specified transmission rate and distance limits.
Cable Guidelines
NOTE:
Building and electrical codes vary depending on the location. Comply with
all code specifications when planning the site and installing cable.
When running cable to the equipment, consider the following:
• Do not run cables where they can be stepped on or rolled over.
• Be sure cables are intact with no cuts, bends, or nicks.
• If the user is making a cable, ensure that the cable is properly crimped.
• Provide proper strain relief for IB cables.
• Support cables using a cable manager mounted above connectors to avoid
unnecessary weight on the cable bundles.
• Bundle cable using velcro straps to avoid injuring cables.
• Keep all ports and connectors free of dust.
• Untwisted Pair (UTP) cables can build up Electrostatic Discharge (ESD) charges
when being placed into a new installation. Before installing category 5 UTP
cables, discharge ESD from the cable by plugging it into a port on a system that
is not powered on.
• When required for safety and fire rating requirements, plenum-rated cable can
be used. Check the local building codes to determine when it is appropriate to
use plenum-rated cable, or refer to IEC standard 850.

Installation

Cable Handling and Bend Radius
Provide proper strain relief by adhering to the following guidelines:
For copper cable, the temporary 90-degree bend can never be more than 0.5
inches tighter than the values listed above for any assembly. This is the absolute
minimum sustained bend radius for each cable AWG size. This measurement is
the distance from the switch panel to the point where the cable makes a
90-degree bend. In other words, this number includes the distance from the
connector stand-off from the panel surface.

Figure 1-2 Fiber Optic Bend Radius
Uninterruptible Power Supply
Consider the following when selecting Uninterruptible Power Supply (UPS)
equipment:
• The minimum amperage requirements for a UPS:
• Calculate VA (Volt-Amps): Locate the voltage and amperage requirements
for each piece of equipment (usually located on a sticker on the back or bottom
of the equipment). Multiply the numbers together to get VA.
• Add the VA from each piece of equipment together to find the total VA
requirement. Then add 30% to determine the minimum amperage
requirements for the UPS.
• Transition time (the time necessary for the UPS to transfer from utility power to
full-load battery power).
• The longest potential time period the UPS might be required to supply backup
power.
• Whether or not the UPS unit also provides online protection.

Installation Tasks Checklist
To perform the actual switch installation, the site implementation engineer must
perform the following tasks, which are detailed in this section.
CAUTION!
Be sure to review the safety information before starting the installation and
during the installation process (refer to Appendix B).
1. Check the installation site to verify the installation of cabinet power feeds, rails,
and grounding.
2. Unpack the equipment and inspect for any shipping damage. Any shipping
damage should be reported to the shipping company.
3. Verify that the equipment shipped matches the packing list.
4. Mark the rack and install the mounting rails.
5. Physically install the switch in the rack.
Tools and Equipment Required
• An ESD wrist strap
• A #2 Phillips screwdriver
• An M6 HEX nut wrench
• Pen (felt-tip) to mark the mounting holes
• Lifting device (e.g., pallet jack) for the 12800-360 and 12800-180
Check the Installation Site
The switches are designed to be installed in an existing server cabinet (not a telco
cabinet), where it can be mounted in a standard equipment rack.
Be sure of the following:
• The cabinet has a full earth ground to provide reliable grounding.
• There is enough room to work on the equipment.
• The equipment will have enough clearance for front and rear access.
• The IB cables can be accessed easily.
• Water or moisture cannot enter the switch.
• The ambient temperature stays between 50° - 113°F (5° - 40° C).
• Cabinet doors do not interfere with front-to-back air flow.
The cabinet should have its own switchable power distribution. If the switch has two
power supplies, it is suggested that a cabinet with dual power distribution units is
used.

It is recommended that cabinet anti-tip devices are used. This is especially true if
installing or removing a switch in the upper half of the cabinet when the lower half
is empty.
Mark the Rack
Allow enough vertical space in the rack for each specific switch installation.
1. Determine the location in the rack of the bottom of the switch.
2. Mark the upper (if applicable) and lower mounting positions on the vertical rails
on the front of the rack.
3. Mark the upper (if applicable) and lower mounting positions on the vertical rails
on the back of the rack.

This section describes the rack mounting instructions for the 12200 and 12300:
Four Post Standard-Depth Rack Installation
In a standard-depth rack, the distance between the front and back mounting posts
is ~28" (700mm). Mounting rails for the 12200 and 12300 are adjustable to
accommodate racks with 26"-33" between mounting posts.
Mounting Hardware Kit Contents:
• One pair of mounting rails adjustable for 26"-33" installation range
• One pair of hat rails, left and right
• #6-32 screws
• M6 cage nuts
•M6screws
Installation
1. Install the hat rails on each side of the switch using three (3) #6-32 screws per
rail. Torque screws to 8in-lb. A typical installation is shown in Figure 1-3. On
the 12300, hat rails are installed with mounting ears towards the power supply
side of the switch. On the 12200, hat rails are installed with mounting ears
towards the port side of the switch.

2. Install eight (8) cage nuts into rack posts, two (2) cage nuts per post. Install the
mounting rails and fasten to cage nuts using six (6) M6 screws. Torque screws
to 30in-lb. Do not install two (2) screws in lower locations on equipment
installation side of the rack until the switch is installed in the rack. Note the
