Figure 8 Removing the Blank Panel
If you are installing only one expansion module in the switch, you
should install the module in slot A. While the module will work in
slot B with slot A empty, the port numbering assignments will
change if you later install a module in slot A. This could affect the
VLAN memberships on the switch and this could require you to
adjust your VLAN configurations.
For example, if you install an AT-A15/SX in slot B of an AT-9006
switch while leaving slot A empty, the switch will assign the port
number 7 to the fiber optic port on the module. If you later install
another AT-A15/SX module in slot A, the switch will automatically
reallocate port number 7 to the new module in slot A and assign
the port number 8 to the module in slot B. If the module in slot B
had been a member of a VLAN other than the Default VLAN, you
would have to reconfigure the switch's VLANs to reflect the
change to the module's port number.
3. Remove the expansion module from the packing material.
Caution
To prevent damaging the module, do not touch any of the
components on the module's circuit board. Handle the module by
its edges or the front faceplate. You should be wearing an anti-
static wristband that has been connected to a suitable earth
ground.
