4 SAN Switch Rack Mount Kit Installation Instructions
Rack Stability
Rack stability protects personnel and equipment.
WARNING: To reduce the risk of personal injury or damage to the
equipment, be sure that:
■The leveling jacks are extended to the floor.
■The full weight of the rack rests on the leveling jacks.
■In single rack installations, the stabilizing feet are attached to the rack.
■In multiple rack installations, the racks are coupled.
■Only one rack component is extended at any time. A rack may become
unstable if more than one rack component is extended for any reason.

Installation and Safety Guidelines
Read the following sections for installation guidelines. Install the SAN Switch in
one of the following ways:
■As a stand-alone unit on a flat surface.
■In an Electronics Industries Association (EIA) cabinet (like the HP 9000
Series Rack).
■In an HP System/e rack.
Selecting an Operating Location
To ensure correct operation of the switch, the location where the switch is in use
must meet the following requirements:
■Adequate supply circuit, line fusing, and wire size, as specified by the
electrical rating on the switch nameplate.
■An air flow of at least 300 cubic feet per minute, available in the immediate
vicinity of the switch.
■If installing the switch in the HP 9000 Series, or comparable EIA rack:
— All equipment installed in the rack should have a reliable branch circuit
ground connection, and should not rely on a connection to a branch
circuit, such as a power strip.
— The rack should be balanced and the installed equipment should be within
the rack’s weight limits. Ensure the rack is mechanically secured to insure
stability in the event of an earthquake.
Cooling Requirements
Cooling air is drawn into the switch chassis by the fans mounted on the rear of the
chassis. The air is expelled through vents in the front (port side) of the chassis,
next to the HP logo. HP recommends installing the switch so that air intake and
exhaust for all components in the rack is flowing in the same front-to-back
direction.
Note: HP highly recommends mounting the switch in a cabinet or rack so that the fans
reside in the front of the cabinet, and the ports (cables) reside in the rear of the cabinet.

6 SAN Switch Rack Mount Kit Installation Instructions
Follow these guidelines to ensure proper air flow, and prevent component
overheating:
■To ensure adequate cooling, install the switch with the non-port side,
which contains the air intake vents, facing the cool-air aisle.
■Verify a minimum of 47 cubic feet/minute (79.8 cubic meters/hour) of air
flow is available to the air intake vents on the non-port side of the switch.
■Verify that the ambient air temperature does not exceed 40° Celsius (104°
Fahrenheit) while the switch is operating.
Caution: Do not block air vents. The switch uses ambient air for cooling.
Power Requirements
The AC power source must meet these requirements:
■Primary AC Input 100–240 VAC (switch auto-senses input voltage) 47–63 Hz
■Correctly wired primary outlet, with circuit protected by a circuit breaker and
grounded in accordance with local electrical codes
■Adequate supply circuit, line fusing, and wire size, as specified by the
electrical rating on the switch nameplate
■Voltage capability of 85–264 VAC
■Input voltage frequency of 47–63 Hz
■Power capability of 75 W maximum
Rack Mount Checklist
Verify that the rack and the area around the rack meets the following
requirements:
■The cabinet must be a standard EIA cabinet.
■Plan a cabinet space that is 1.5 rack units high (2.6 inches; 6.7 cm), 19 inches
(48.3 cm) wide, and at least 23 inches (68.6 cm) deep.
■Ground all equipment in the cabinet through a reliable branch circuit
connection, and maintain ground at all times. Do not rely on a secondary
connection to a branch circuit, such as a power strip.

7SAN Switch Rack Mount Kit Installation Instructions
■Ensure that air flow and temperature requirements are met on an ongoing
basis, particularly if the switch is installed in a closed or multi-rack assembly.
■Verify that the additional weight of the switch does not exceed the cabinet’s
weight limits or unbalance the cabinet in any way.
■Secure the cabinet to insure stability in case of unexpected movement.
Note: For proper air flow, the SFP media side of the switch must face the rear of the
rack. This mounting allows air to enter from the front of the rack and to exhaust at the
rear of the rack, similar to other rack-mounted equipment. This prevents switch
overheating.

15SAN Switch Rack Mount Kit Installation Instructions
6. For the SAN Switch 2/32 and SAN Switch 2/16, perform step a. For the SAN
Switch 2/8, perform step b.
Caution: Do not use any other screws other than the fourteen that are
provided. Use of any longer lengths can cause damage to internal
components.
Note: The inner rails work for all three SAN switches—SAN Switch 2/32, SAN Switch
2/16, and SAN Switch 2/8. The mounting holes in the inner rails are marked with 32,
16, and 8. Use the appropriately labeled mounting holes when installing the inner rails
on a switch. For example, to install the inner rails on the SAN Switch 2/32, use the
mounting holes labeled with 32.
When viewing a rack from the front, the left rails are used in the left side of the rack and
the right rails are used in the right side of the rack. The rails must match up—right inner
with right outer and left inner with left outer. Note that the SAN switch mounts in the
rack with its front, the port side, facing the back of the rack. The rear of the switch, the
AC side, faces the front of the rack.

16 SAN Switch Rack Mount Kit Installation Instructions
a. Assemble the two inner rails (one on each side) to the switch using the
appropriate number (from step 5) of #8-32 x 3/16-inch Phillips pan-head
screws as shown in Figure 7.
Note: The rail kit provides fourteen #8-32 x 3/16-inch screws for assembling the inner
rails. Each switch requires a different number of these screws. For example, Figure 7
shows the an inner rail being attached to the SAN Switch 2/16 with five screws.
Attaching both inner rails requires ten screws.
Figure 7: Assembling the inner rails
Note: For factory integration only, tighten the #8-32 x 3/16-inch Phillips pan-head
screw with thread lock and torque between 6 to 8 inch-pounds.

17SAN Switch Rack Mount Kit Installation Instructions
b. For the SAN Switch 2/8, assemble the two inner rails (one on each side)
to the switch and plenum using the appropriate number (from step 5) of
#8-32 x 3/16-inch Phillips pan-head screws as shown in Figure 8.
Note: The plenum is only a required part of this installation when the SAN Switch 2/8
is installed in the HP System/e rack. The plenum is not needed if the switch is installed
in an HP 9000 Series or comparable EIA rack.
Verify that the plenum (part number A7346-00001) is preinstalled on the SAN Switch
2/8 before proceeding. The plenum is required for the SAN Switch 2/8 rack mount
only, as it allows air to dissipate at the rear of the rack, preventing overheating.
If the plenum is not preinstalled on the SAN Switch 2/8, refer to the
HP StorageWorks
SAN Switch 2/8 Version 3.1.x Installation Guide
for complete plenum installation
instructions.
