FEDERAL COMMUNICATIONS COMMISSION
AND INDUSTRY CANADA RADIO FREQUENCY INTERFERENCE
STATEMENTS
This equipment generates, uses, and can radiate radio-frequency energy, and if
not installed and used properly, that is, in strict accordance with the manufacturer’s
instructions, may cause inter ference to radio communication. It has been tested
and found to comply with the limits for a Class A computing device in accordance
with the specifications in Subpart B of Part 15 of FCC rules, which are designed
to provide reasonable protection against such interference when the equipment
is operated in a commercial environment. Operation of this equipment in a residential area is likely to cause interference, in which case the user at his own expense
will be required to take whatever measures may be necessary to correct the i
nterference.
Changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.
This digital apparatus does not exceed the Class A limits for radio noise emis sion
from digital apparatus set out in the Radio Interference Re gulation of Industr y
Canada.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant
les limites applicables aux appareils numériques de classe A prescrites dans le
Règlement sur le brouillage radioélectrique publié par Industrie Canada.
CE Mark Warning
This equipment complies with the requirements relating to electromagnetic compatibility, EN 55022 class A for I TE, the essential protection requirement of Council

3. Installation
3.1 Selecting a Site for the Equipment
CAUTION: Before you install the switch, we strongly recommend that you:
1. Place the extender within an appropriate ventilation environment. Allow at least
1" (2.5 cm) of space around the unit.
2. Position the extender and the relevant components away from sources of
electrical noise such as radios, transmitters, and broadband amplifiers.
3. Place the extender away from environments beyond the recommended moisture
specifcation (10–90% humidity).
3.2 Desktop Installation
1. Install the ex tender on a level surface that can support the weight of the unit and
the relevant components.
2. Plug the female end of the provided power cord to the extender and plug the
male end to the power outlet.
3.3 Rackmount Installation
To mount the switch in a rack:
1. Disconnect all the cables from the extender.
2. Place the unit right-side -up on a hard, flat surface with the front facing you.
3. Place a mounting bracket (not included) over the mounting holes on one side of
the unit.
4. Insert the screws and fully tighten with a screwdriver.
5. Repeat the t wo previous steps for the other side of the unit.
6. Insert the unit into the rack and secure with screws (not included).
7. Reconnect all the cables.
3.4 Installing Network Cables
1. Use crossover or straight-through cable to connect the switch with PCs,
other switches, hubs, and/or routers. All the ports on the extender support
Auto-MDI/MDI-X.
2. Use CAT3, 4, 5, or 5e UTP/STP cables to make a valid connection and obtain
optimal performance. Table 3-1 lists what cables work with each network speed.
