Stackable Ethernet Hubs
User Manual
GENERAL DESCRIPTION
The FlexCenter 200 is a family of 12/24 port dual speed 10/100 and 100 stackable
workgroup Ethernet hub repeaters. They feature two optional interface modules used
for stacking and uplink interfaces to multimode and single-mode fiber hubs, switches
or workstations. This User’s Manual describes the following base models:

4584 100Fx, Fiber, ST/SM, SD, 100-200 m / 328-656 ft.
4590 STK, Stack Module
The FlexCenter’s 12/24 RJ45 ports provide 10Base-T or 100Base-Tx unshielded
twisted pair (UTP) wiring. Its fiber interface modules provide 100Base-Fx multimode
or single-mode SC or ST connectivity options for a variety of applications. The stack-
ing module provides cable connection between stacked hubs.
The FlexCenter monitors and reports port activity. It detects operational devices
connected and displays their connection via a per-port green Link / Partition (L/P)
LED. If a port violates transmission rules, it is disconnected automatically (parti-
tioned) and the L/P LED starts flashing indicating the “Partition” error status. The port
is reconnected only after normal behavior is restored. The per-port speed is indi-
cated by a second per-port LED that flashes while not connected to a device, turns on
“solid” when detecting a 100 station and turns “off” when detecting a 10 station.

Application 5. Single Wiring Closet / Multiple Hubs
This application depicts a single-wiring-closet-based network. It is a typical stacking
application of the FlexCenter 200. In this case six hubs are stacked, accommodating up
to 150 stations (144 ports plus six modules).
Application 6. Multiple Wiring Closets / Multiple Hubs
This case depicts two stacks of hubs connected via a fiber uplink. Since an extended-
distance-bridge-based module is used, full-duplex operation is possible for distances of 2
km (1.2 mi.) using multimode fiber, and 58 km (35 mi.) using single-mode fiber.
