Installation
66
❑
You should verify that you are using the appropriate type of
fiber optic cabling. For an AT-8016F Series, AT-8026FC, or
AT-8088/xx Series switch, refer to ”Planning the Installation”
on page 50. For an optional GBIC module, refer to the GBIC
Installation Guide. For an optional fiber optic expansion
module, refer to the Expansion Module Installation Guide.
❑
You should verify that the operating specifications of the
switch’s fiber optic port are compatible with the fiber optic
port on the remote end-node. For example, you cannot
connect a fiber optic port with a maximum distance of 2
kilometers and an operating wavelength of 1310 nm to
another fiber optic port that has a maximum distance of 40
kilometers (24.8 miles) and an operating wavelength of 1550
nm.
❑
If your network topology will contain a loop where two or
more network devices can communicate with each other over
more than one data path, do not connect the network cables
forming the loop until after you have activated the Spanning
Tree Protocol (STP) on the switch. Data loops can adversely
affect network performance. For instructions on how to
activate STP, refer to the AT-S39 Management Software
User’s Guide.
❑
If you are creating a port trunk, do not connect the cables of
the trunk to the switch until you after have configured the
trunk using the switch’s management software. Connecting
the trunk cables to the switch before you have configured the
software will result in a data loop, which can adversely affect
network performance. For instructions on how to configure a
port trunk, refer to the AT-S39 Management Software
User’s Guide.
4. If you installed a fiber optic or twisted pair expansion module,
stacking module, or GBIC module, connect the data cable to the
port on the module.
5. Apply AC power to the switch by plugging the power cord into the
AC power connector on the back panel of the unit and plugging the
other end into a wall outlet.
Warning
The power cord is used as a disconnection device. To de-energize
equipment, disconnect the power cord.
