Selecting a Site for the SwitchBlade x8106
Please perform the following procedure to determine the suitability of the 
site for the chassis:
1. Verify that the equipment rack is safely secured so that it will not tip 
over. You should install devices starting at the bottom of the rack, with 
the heavier devices near the bottom.
2. Verify that the power outlets for the chassis are located near the unit 
and are easily accessible.
3. Verify that the power sources are on different A/C circuits to protect 
the unit from a power circuit failure.
4. Verify that the site has dedicated power circuits or power conditioners 
to supply reliable electrical power to the network devices.
5. Verify that the site allows for easy access to the ports on the front of 
the chassis so that you can easily connect and disconnect the network 
cables, as well as view the unit’s LEDs.
6. Verify that the site allows for adequate air flow around the unit and 
through the cooling vents. The ventilation direction for the main section 
of the chassis is from left to right (when facing the front of the chassis), 
with the fan module drawing air out of the chassis. The power supplies 
have fans that draw air from the front to the back.
7. Verify that the site has a reliable and earth (grounded) power supply 
source, preferably dedicated and filtered.
8. Verify that the twisted pair cabling is not exposed to sources of 
electrical noise, such as radio transmitters, broadband amplifiers, 
power lines, electric motors, and fluorescent fixtures.
9. Verify that the site protects the chassis from moisture, water, and dust.
Here are other guidelines to consider:
Switch ports are suitable for intra-building connections, or where 
non-exposed cabling is required.
Do not place objects on top of the chassis.
The power cords provided with the AT-SBxPWRSYS1 and AT-
SBxPWRPOE1 AC Power Supplies for 100-125 VAC installations 
have 20 Amp, 125 V NEMA 5-20P plugs. The plugs are only 
compatible with NEMA 5-20R receptacles. See Figure 28 on page
