3. Building Feasible Networks
This chapter describes the network topology for hybrid 10Mbps and 100Mbps
networks, cabling requirement for connections, the interoperability between
hubs and switches and the function of bridge Up-Link port. Please turn over
the page to see the different Topologies.
3.1 Network topology for AcerHub ALH-608ds : The factors for ALH-608ds
dual-speed network implementation are:
• For stand-alone one, the ALH-608ds consists of separate 10Mbps and
100Mbps network domains with one built-in switch to inter-connect the data
in domains, as shown in Figure 3-1.
Figure 3-1 Separate domains in ALH-608ds.
• 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. The Slave hubs will provide a uplink port
with bridge functional(so called Bridge Uplink Port) that utilizes the first
connection port as well, as in Figure 3-2.
3-1
User's Manual
608-UM 1/8/99 2:34 PM ≠∂≠±21
Figure 3-2 Master and Slave hubs in stacking ALH-608ds.
Note:
1. To concern the convenience of the cross-wiring connection
between hubs, ALH-608ds provide 1 normal port (marked as "II)
and 1 cross-over port (marked as "X"). These 2 ports are wired to
each other by different wiring assignments.
2. The up-link port utilizes the first connection port with "X"
sign.When you connect to another hub by this uplink port, you
cannot simultaneously connect a PC to this port in which "II" sign is
marked . The reason being that if a PC is connected to it, the
physical signal in the cable will be corrupted.
• 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 3-3.
Figure 3-3 Auto Data looping prevention in ALH-608ds.
User's Manual
3-2
608-UM 1/8/99 2:34 PM ≠∂≠±22
• 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 3-4.
Figure 3-4 Unlimited cascading of ALH-608ds.
• All PCs with 10Mbps network adapter cards transmit data at 10Mbps and
form the 10Mbps network domain, as shown in Figure 3-5.
• 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 3-5.
Figure 3-5 Network domains and bridged uplink.
3-3
User's Manual
608-UM 1/8/99 2:34 PM ≠∂≠±23
• 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.
3.2 Interconnection to Hubs and Switches
3.2.1 Connecting to Ethernet Hubs : The factors governing hub
interconnection are:
• The hubs are only connected by uplink port. ALH-608ds 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-608ds are stacked together, users can connect to hubs by
the uplink port in slave hubs. Therefore other hubs can perform another
class-II cascading, as shown in Figure 3-6.
Figure 3-6 Connect to Ethernet Hubs.
User's Manual
3-4
608-UM 1/8/99 2:34 PM ≠∂≠±24
3.2.2 Connecting to Ethernet Switches : The factors governing hub and
switch interconnection are:
• The hubs are only connected to Ethernet switches by an uplink port. ALH608ds 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.
Figure 3-7 Connect to Ethernet Switches.
No matter if the ALH-608ds hubs are stacked together or not, the user always
can connect to Ethernet switches by the uplink port.
