The maximum length of the primary-to-secondary switch interconnect is computed according
to the following tables: (all distances are in meters).
Using CAT-5e/6 100/1000Mbps cable:
Distance Between Secondary Switch
and Its Farthest AP
Max. Switch Interconnect Distance
(Copper Interconnect Cable)
150 (with EXRE)
50
Note: Beyond 100 m, copper-based cables require a range extender (EXRE).
Using fiber media cable:
Distance Between Secondary Switch
and Its Farthest AP (*)
Max. Switch Interconnect Distance
(Fiber Interconnect Cable)
400 (with EXMC)
50
50 (with EXRE)
450
(*) The total length of the copper-based cable to/from EXMC must be less than 2m.
Using mixed media types:
Distance Between Secondary Switch
and Its Farthest AP (Copper cable)
Max. Switch Interconnect Distance
(Fiber Interconnect Cable)
100
400
150 (with EXRE)
300
Distance Between Secondary Switch
and Its Farthest AP (Fiber cable) *
Max. Switch Interconnect Distance
(Copper Interconnect Cable)
400 (with EXMC)
50
(*)The total length of the copper-based cable to/from EXMC must be less than 2m.
Note: EXMC and EXRE are not to be used with uplink ports, for example, in the
case of Interconnect.
To connect an AT-EXLS-3000 pair for redundancy:
1.
Verify that both switches are running the same firmware release and that it is the newest release
that supports Resiliency.
2.
Verify both switches have a valid AT-EXLS-3000 Redundancy license.
3.
Connect the interconnect cable to the LAN2 port of the AT-EXLS-3000 primary switch and to
the LAN2 port of the AT-EXLS-3000 secondary switch.
4.
A direct cable connection between a redundant AT-EXLS-3000 pair is not mandatory: Any L2
or L3 connection is sufficient as long as each one of the switches can ping a common reference
IP address.
