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.

500.book Page 7 Thursday, September 2, 1999 1:17 PM

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 1MΩ 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
