AT -A45/xx Series Expansion Module
The AT-A45/xx series of expansion modules
provide optional uplink ports for AT-8000
Series, AT-8500 Series and AT-8600 series Fast
Ethernet switches. Hot-swappable, they plug
into the expansion slot(s) on the front of the
switches without having to power OFF the
switch.Their modularity offers flexibility in build-
ing or expanding your network. A maximum of
two expansion modules can be installed in a
switch, depending on the number of slots on
the model.

Allied Telesis Allied Telesis
The AT-A45/SC-SM15 singlemode transceiver
is a high-performance module for bi-directional
serial optical data communications, operating at
a nominal wavelength of 1310nm.The transmitter
section uses a multiple quantum well laser and is
class 1 laser-compliant according to international
Safety Standard IEC-825.The receiver section
uses a planar InGaAs PIN photodiode for low
dark current and excellent responsivity.
The AT-A45/SC and AT-A45/MT multimode
transceivers are ideal for the 2km multimode
fiber backbone.The transmitter section utilizes
1300nm Surface Emitting InGaAsP LEDs.
AT -STACKM Expansion Module
The optional AT-STACKM module provides
a Gigabit Ethernet connection between compati-
ble AT-8000 Series Fast Ethernet switches for
improved network performance.The AT-STACKM
modules can be installed without powering off
the switches. A maximum of two stack modules
can be installed in a switch.
Note: The GBIC module for the AT-A47 expansion
module is sold separately. Refer to the GBIC module
Installation Guide or contact your Allied Telesis sales
representative for additional information on available
GBIC modules.
