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.
update ALH-316_324UM.qxd 11/10/99 8:42 AM ›¶›– 11 • 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.
