1.Overview
Congratulations on your purchase of the AcerHub 616ds. The AcerHub ALH-
616ds is a 16-port dual-speed fast Ethernet repeater hub for connection with
multiple PCs to a workgroup LAN (Local Area Network) environment to
sharenetwork resources.
1.1 Product goal
AcerHub ALH-616ds provides high-speed and easy access to the LAN and
Intranet both for SOHO (Small Office/ Home Office) and corporations. Itallows
data transmission at speeds of 10 Mbps or 100Mbps, depending if theconnected
device is running at 10Mbps or 100Mbps. Besides the high-speed data
access, the AcerHub ALH-616ds also supports one uplink port for Class-II
cascading connection between hub stacks. The uplink port will support the
bridge function that permits a distance of 100 meters for data transmission
in Class-II cascading and eliminates the repeater count limitation in IEEE
802.3u specifications. It will be easy to construct your own LAN with ALH616ds by this explicit expanding capability of data transmitting distances and
user accounts.
Installation of AcerHub ALH-616ds is relatively simple and all you have to
dois plug the cables from the adapter cards to the ports, check the LEDs
and you can start networking.
1.2 Product Features
AcerHub ALH-616ds provides the following features:
• 16-port dual-speed hub, each port is a 10/100 Mbps dual-speed connection
with network speed auto-detection
• Fully complies with IEEE 802.3 and 802.3u specifications
• Built-in switching function to connect 10 and 100Mbps network domains
• Stackable function to provide maximum stacking of 5 sets as a single hub
count by SCSI-II cables
• In slave hub mode, an uplink port with bridge function which provides
scalable network expansion.(This function is very useful in constructing a
large network,refer section 3.1 for details.)
• Built-in switch auto-disable function to avoid data looping when stacking
• External switching power supply for lower power consumption and heat
emission
• Compact design for SOHO desktop environment for easy networking
