Ensure a cover plate is installed on any empty switch power supply slot. A cover plate is required for safe operation, and

to ensure proper switch cooling.

To avoid energy and mechanical hazards, never allow any partof body, jewelry, tool, or other foreign object to enter any

module or power supply slots.

Ensure that for any switch slot into which no module is installed, the cover plate is installed to cover the slot. A coverplate

is required for safe operation, and to ensure properswitch cooling. For safety, user should never have more thanone

module slot uncovered at a time while the switch is powered on.

CAUTION:

Ensure the power source circuits are properly grounded, then use thepower cord supplied with the switch to connect it to

the power source. If installation requires a different power cord than the one supplied with the switch and power supply, be

sure the cord is adequately sized for the switch's current requirements. In addition, be sure to use a powercord displaying

the mark of the safety agency that defines the regulations for power cords in user's country. The mark is an assurance that

thepower cord can be used safely with the switch and power supply.

When installing the switch, note that the AC outlet should be near the switch and should be easily accessible in case the

switch must bepowered off.

Ensure the switch does not overload the power circuits, wiring, and over current protection. To determine the possibility of

overloading the supply circuits, add together the ampere ratings of all devices installed on the same circuit as the switch

and compare the total with the rating limit for the circuit. The maximum ampere ratings are usually printed on the devices

near the AC power connectors.

Do not install the switch in an environment where the operating ambienttemperature might exceed 40°C (104°F).

Allow three to four inches of space around the sides and back of theswitch to make sure the air flow for the switch is not

restricted.

Cabling Infrastructure: Ensure the cabling infrastructure meets the necessary network specifications. See the following table for cable

types and lengths.

Port Type

Cable Type

Twisted-pair cables

10/100/1000Base-

For either 10, 100 Mb/s or 1000 Mbpsoperation:Category 5 or better, 100-ohm UTP or shielded

Twisted-pair (STP) balanced cable. For 1000 Mbps (Gigabit) operation, Category 5e cabling or

better is recommended.

Fiber optic cables

Gigabit-SX(On

Multimode fiber-optic cables fitted with LC connectors

Gigabit-LX (On

Single-mode fiber-optic cables fitted with LC connectors.

Gigabit-LX-

The multimode cables specified for the Gigabit-SX mini-GBIC may also be used, but a mode

Gigabit-LH (On

Single-mode fiber-optic cables designed forGigabit Ethernet and fitted with LC connectors.

Gigabit-LH-

LCmini-GBIC)

NOTE:

Gigabit-LH - The transmission distances are dependent on the particular fiber loss and coupling loss involved, among other factors, and can be estimated from the

optical loss budget. For distances less than 20 km, a 10 dB attenuator must be used. For distances between 20 km and 40 km, a 5dB attenuator must be used. Attenuator

can be purchased from most cable vendors.
