Using the 512-Bit Rule

When configuring Fast Ethernet™ networks, use the 512-bit rule to determine
masimum cable lengths for each half-duplex collision domair.

In a half-duplex network, maximum
cable lengths are determined by the
round trip delay limitations of each Fast
Ethernet

™ collision domain. (Switches

and routers divide the network into
separate Ethernet™ collision domains.)
The 512-Bit Rule determines maximum
distances by calculating the collision
domain round-trip delay in bit-times.

To calculate a collision domain
round-trip delay in bit-times, find
the longest path between any two
terminal devices in the collision
domain. Calculate the round trip
delay by multiplying the length of
the cable (in meters) by the delay
per meter (in bit-times (BT)), then
take the sum of all cable delays
plus station (DTE), repeater, and
multi-port media converter port
delays. If the result is less than or
equal to 512 bit-times, the path is
good.

surface on rubber
foot.

• Position and

secure each
rubber foot as
shown.

3. Return E-FX-HB-xx00 to upright position.

OPERATION

Use the status LEDs to monitor E-FX-HB-xx00 operation in the network.

HUB INDICATORS

P(o)W(e)R Steady LED indicates E-FX-HB-xx00 is

connected to external AC power.

COL(lision) Flashing LED indicates network collisions.
G(lobal) F(ault) S(tatus) Steady LED indicates the presence of a

partitioned or isolated port. (A port is
partitioned automatically after a collision
occurs during 60 or more consecutive
attempts to transmit to the port; a port is
isolated if more then two consecutive false
carrier events are received.)

NOTE: The hub unpartitions/unisolates the
port when network traffic becomes normal.
The GFS LED remains illuminated until the
partition/isolation condition is corrected.)

B(ack)B(one) & 100BASE-FX INDICATORS

STAT(us) Steady LED indicates, for each port, a valid

link and no partition or isolation.
Dark LED indicates, for each port, that port

is not linked, is isolated, or is partitioned.

ACT(ivity) Flashing LED indicates, for each port,

reception of data packet(s).

Power the E-FX-HB-xx00

NOTE: When the hub is connected to an AC outlet supplying 100-240VAC at
50-60 Hz, the hub automatically powers ON

To power ON the E-FX-HB-xx00:

1. Locate power receptacle at back of E-FX-HB-xx00.

2. Plug unit end (female) of power cord into E-FX-HB-xx00 power
receptacle.

3. Plug outlet end (male) of power cord into correct voltage AC wall
socket.

4. At E-FX-HB-xx00 front, verify that P(o)W(e)R LED is illuminated.

Optionally Cascade Hubs

AT BACK

To cascade hubs by installing adapter cable(s) between stacked hubs:

1. Locate uplink adapter installed on E-FX-HB-xx00 9see page 4) and
adapter cable ACC-0201.

2. Install one end of adapter cable to UPPER connector on expansion
adapter on lowest hub in stack.

3. Install one end of adapter cable to LOWER connector on expansion
adapter on next hub in stack.

4. Continue steps 2-3 until installation is complete.

AT FRONT

To cascade hubs by installing fiber cables between hubs:

1. Locate or build 100BASE-FX compliant two-stranded fiber cable
with appropriate TX to RX connectors installed at both ends.

2. Connect male TX and RX cable connectors at one end of cable to
TX and RX female connectors, respectively, on front of one hub.

3. Connect male TX and RX cable connectors at other end of cable to
RX and TX connectors, respectively, on front of second hub.

Optionally Connect to Backplane through TX Uplink

NOTE: Refer to 512-bit rule (page 3) to keep cable lengths within acceptable
bounds.

To connect twisted-pair cable from E-FX-HB-xx00 100BASE-TX uplink
adapter to network:

1. Locate 100BASE-TX uplink adapter installed at E-FX-HB-xx00 back.
(See page 5.)

NOTE: AutoCross

™

feature on 100BASE-TX uplink adapter allows
use of either straight-through or crossover 100BASE-TX cable
configuration.

2. Locate or build 100BASE-TX compliant cables with male RJ-45 plug
connectors at both ends. (See page 14.)

3. Connect male RJ-45 plug connector at one end of cable to
E-FX-HB-xx00 100BASE-TX uplink adapter RJ-45 jack connector.

4. Connect male RJ-45 plug connector at other end of cable to RJ-45
jack connector on 100BASE-TX network device.

Optionally Connect to Backplane through FX Uplink

NOTE: Refer to 512-bit rule (page 3) to keep cable lengths within acceptable
bounds.

To connect fiber cable from E-FX-HB-xx00 100BASE-FX uplink adapter to
network:
