3.3 Network topology for AcerHub ALH-316ds/324ds
The factors for ALH-316ds/324ds dual-speed network implementation are:
• For stand-alone one, the ALH-316ds/324ds consists of separate 10Mbps
and 100Mbps network domains with one built-in switch to inter-connect
the data in domains, as shown in Figure 3-2.
316ds/324ds
Figure 3-2 Separate domains in ALH-316ds/324ds.

›¶›– 10
• The hub will be divided into Master and Slave hubs when they are
stacked together. The upper most hub is the Master hub, and other hubs
are Slave hubs. The Master hub continues to use the built-in switch but
the switch in the Slave hubs will be disabled, as in Figure 3-3.
Figure 3-3 Master and Slave hubs in stacking ALH-316ds/324ds.
Note: 1. To concern the convenience of the cross-wiring connection
between hubs, ALH-316ds/324ds provide 1 cross-over port
(marked as"X").
2. The up-link port utilizes the first connection port with "X"
sign.When you connect to another hub by this uplink port.
• The built-in switches in slave hubs will be disabled automatically to avoid
data looping from multiple inter-connections of hubs, as shown in Figure
3-4.
Figure 3-4 Auto Data looping prevention in ALH-316ds/324ds.

• By way of an uplink port with a Bridge function, the limitations on
100Mbps hub count(maximum 2) can be eliminated. The hub count is
unlimited and cable length between hubs can reach 100meters, as
shown in Figure 3-5.
Figure 3-5Unlimited cascading of ALH-316ds/324ds.
• All PCs with 10Mbps network adapter cards transmit data at 10Mbps
and form the 10Mbps network domain, as shown in Figure 3-6.
• PCs with 10/100Mbps network adapter cards will auto-negotiate and
switch the network speed to 100Mbps. They transmit data at 100Mbps
and form the 100Mbps network domain, as shown in Figure 3-6.
Figure 3-6 Network domains and bridged uplink.
• The data in 10Mbps or 100Mbps domain will be inter-connected by
internal built-in switch in the Master hub consequently.
• All hubs delivering data by the shared-bus always work on half-duplex
mode; that is, data can be sent or received at one time in one direction.

3.4 Interconnection to Hubs and Switches
3.4.1 Connecting to Ethernet Hubs : The factors governing hub
interconnection are:
• The hubs are only connected by uplink port. ALH-316ds/324ds will
automatically transmit at 10Mbps network speed when connecting to
10Mbps Ethernet hubs and 100Mbps network speed if connected to
100Mbps hubs.
• If multiple ALH-316ds/324ds are stacked together, users can connect to
hubs by the bridge uplink port in master/slave hubs. , as shown in Figure
3-7.
Figure 3-7 Connect to Ethernet Hubs.
3.4.2 Connecting to Ethernet Switches : The factors governing hub and
switch interconnection are:
• The hubs are only connected to Ethernet switches by an uplink port.
ALH-316ds/324ds will automatically work at 100Mbps network speed
when connected to 10/100Mbps Ethernet switching ports and it will work
at 10Mbps network speed if connected to 10Mbps switching ports.
