Selecting a Site for the SwitchBlade x3112
Please observe the following site requirements for the switch:
The equipment rack must be safely secured so that it will not tip
over. Devices in a rack should be installed starting at the bottom,
with the heavier devices near the bottom of the rack.
The power outlet for the switch should be located near the unit and
should be easily accessible.
The power sources for multiple power supplies of the same type
should be on different A/C circuits to protect the unit from a power
circuit failure.
Use dedicated power circuits or power conditioners to supply
reliable electrical power to the network devices.
The site should provide 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.
Air flow around the unit and through the side and rear vents should
be unrestricted.
The site should provide a reliable and earth (grounded) power
supply source, preferably dedicated and filtered.
Twisted pair cabling must not be exposed to sources of electrical
noise, such as radio transmitters, broadband amplifiers, power
lines, electric motors, and fluorescent fixtures.
Switch ports are suitable for intra-building connections, or where
non-exposed cabling is required.
Do not place objects on top of the switch.
Do not expose the switch to moisture or water.
The site should be a dust-free environment.
The power cords provided with the AT-SBxPWRSYS1 and AT-
SBxPWRPOE1 Power Supplies for 100-125 VAC installations
have 20 Amp, 125 V NEMA 5-20P plugs. The plug is only
compatible with a NEMA 5-20R receptacle. See Figure 33 on page
75.
