Positioning and Installing the Switch
Allow adequate ventilation The switch contains two fans to air-cool the internal circuitry. The air
is drawn in from the left of the unit and expelled through the outlet
grills on the right side and the rear.
To ensure correct airflow, leave 100 mm (4 inches) free space on both
sides and behind the switch. Do not allow the intake or outlet grills to
become blocked.
On a desktop To install the switch in a desktop environment:
1 Find the four rubber feet in the pack that contains the rack
mounting kit.
2 Remove the backing strip from each of the four feet.
3 Attach the four rubber feet to the underside of the switch (to
ensure that the switch stands firmly).
4 Place the switch on a stable, flat surface.
5 Ensure that the air intake (on the left) and fan outlets (on the
right side and rear) are not blocked.
Warning The switch’s lifetime and operational reliability can
be seriously degraded by inadequate cooling.
Rack requirements Install the switch in a standard rack in accordance with IEC297 (or
similar); if the minimum outside measurements of the rack are 600 x
600mm (23.5 x 23.5inches), you must allow 190mm (7.5 inches) of
space at the rear.
Mounting kit The switch is delivered with a kit to attach it to a standard 19-inch
equipment rack (with side support rails). The kit contains two mount-
ing brackets and four screws (for attaching the brackets to the sides
of the switch).
Tools required for
positioning in a rack
In addition to the mounting kit, you need the following items to
mount the switch in a rack:
Standard 19-inch rack with side support rails.
3 mm screwdriver.

C H A P T E R 1 Intel Express 520T Switch

Customer-supplied screws for securing the switch in the rack.
Mounting screws are not provided because the required sizes
may vary from rack to rack.
In an equipment rack To mount the switch in a standard equipment rack:
1 Attach the mounting bracket marked “Left” to the left-hand side
of the switch, and attach the mounting bracket marked “Right”
to the right-hand side of the switch, using the four screws pro-
vided.
Make sure that you attach the mounting brackets to the correct
sides. Otherwise the switch will not align correctly in the
equipment rack.
2 If the four rubber feet prevent the switch from standing firmly
on the equipment rack’s side support rails, remove them.
3 Set the switch in the equipment rack, and make sure there is
adequate space for air flow around the switch (see “Allow ade-
quate ventilation” in “Positioning and Installing the Switch”, p.
7).
4 Screw the mounting brackets securely to the equipment rack.
Ambient temperature If the switch is installed in a closed or multi-rack assembly, the oper-
ating ambient temperature of the rack environment may be greater
than the ambient temperature of the room. Make sure that the temper-
ature of the rack environment does not exceed the recommended op-
erating temperature for the switch.

Installing a Module
Introduction You can increase the connectivity options of your switch by installing
a module.
Warning Modules are not designed to be installed in, or removed
from, the switch while it is in operation. You must
power off the switch before attempting to install or
remove a module.
Static-free working area The module’s printed circuit board is an Electrostatic Sensitive De-
vice and should be handled only in a static-free working area; other-
wise, the printed circuit board may fail or be degraded.
Avoiding damage to the
circuit board
If you remove the plate covering the slot on the front of the switch,
for example, to install or remove a module, follow this procedure to
avoid damage to your printed circuit board:
Warning Do not remove the plate unless the switch is discon-
nected from the main power supply.
1 Disconnect the switch from the main power supply.
2 Ground the switch before you handle the printed circuit board.
3 Connect yourself to a non-painted/non-isolated part of the
grounded switch (for example the back panel) using a wrist
strap with 1M resistance to ensure that you carry the same
electrostatic charge as the enclosure.
4 Remove the plate covering the slot.
Installing a module To install a module:
1 If the switch is already operational, disconnect it from the main
power supply.
2 Follow the instructions in “Avoiding damage to the circuit
board” above.
3 Unscrew the screws of the plate covering the slot on the front of
the switch. Save these screws and plate.
4 Insert the module into the slot (following the instructions in the
module’s User Guide). Place your thumbs just beneath the
screws on the front panel of the module and push in the module.
Secure it using the retaining screws.

Removing the module
To remove a module:
1 If the switch is already operational, disconnect it from the main
power supply.
2 Follow the instructions in “Avoiding damage to the circuit
board” above.
3 Unscrew the screws securing the module.
4 Pull the module gently to disengage the connectors fully from
the socket on the motherboard. Slide the module out com-
pletely.
5 Cover the empty module port with the plate and secure using
the screws.
Connecting Other Devices
Introduction Incorrect cabling is often the cause of network configuration prob-
lems
Use shielded cables Shielded cables normally comply with EMC and FCC emission lim-
its.
Only use unshielded cables when it is explicitly specified in the in-
stallation manual of the device in question.
Cables for the LAN Ports Ports on the switch are wired MDI-X, so use the following cable:
If you connect the switch to a... Then use a...
Workstation or server Straight-through cable 1:1
Device with MDI-X ports (for exam-
ple another Intel switch or hub)
Crossover cable
Device with MDI ports Straight-through cable 1:1
