available on the second switch. Note: The Eth.1 (M) port on the expansion LAN switch is
reserved for connection to the main CPU.
Choose the cable length based on the distance from the main frame to the expansion frame.
0.6 meter (Motorola p/n FKN8561A) - This cable is used for local connection of the
main CPU to the expansion switch, or connection of the first LAN switch to the
second, if such exists.
2 meter (Motorola p/n FKN8562A)
3 meter (Motorola p/n FKN8563A)
The main CPU must be connected to the Eth1 (M) port only. If an additional switch is
used, the Eth2 port on first switch should be connected to the Eth1 (M) port on the
second switch.
No devices or equipment other than the main CPU or expansion modules may be
connected to the expansion LAN switch ports.
In systems with several expansion frames, the ACE3600 STS can be used to provide automatic
switch connection configuration. The following physical connections are assumed:
A system with one expansion frame is connected directly to the main CPU.
A system with 1-7 frames (frame IDs 1-7) is connected via one switch (to expansion
LAN switch ports Eth2-Eth8 respectively.)
A system with 1-13 frames is connected via two switches (frame IDs 1-6 connected to
expansion LAN switch 1 ports Eth3-Eth8 respectively and frame IDs 7-13 connected
to expansion LAN switch 2 ports Eth2-Eth8 respectively.)
If the expansion frames are not physically connected as described above, the switch connection
must be manually configured in the STS Switch Connections dialog. For more information,
see the ACE3600 STS User Guide.
