2.2.3: Magnum DS8016-E model, 100Mbps -only
The Model DS8016-E is like the DS8016-A except that it’s speed is internally
fixed at 100Mbps on all ports. It is not dual-speed. It has no bridge inside. It is used for
100Mbps-only applications, and it can operate stand-alone or stacked with the other DS8016-
B and DS8016-A models.
Special orders of this model can be built with some ports fixed at 10Mb. If your
application requires a mix of fixed 100Mb and fixed 10 Mb ports, request a special quote.

Magnum DS8016 Stackable Hub
The Magnum DS8016-R is like the DS8016-B except that the front panel has
the LEDs, and all the connecting ports and power feeds are in the back. This is convenient
for rack-mounting where cabling is accessed from the rear of the rack while the operating
status LEDs are monitored from the front. Typically such arrangements are found in telco
rack installations.
The Magnum DS8016-R is dual-speed, and has a bridge module inside. The
bridge module interconnects 10 Mbps and 100Mbps domains, allowing all connected users
to talk to each other. The DS8016-R operates stand-alone, i.e., it is a non-stackable model.
In addition, the MII port in the rear of other DS8016 models is not present for the DS8016-R.
Normally the DS8016-R is quipped with an optional internal 48VDC power
supply (See Appendix A). There is an additional option of a dual-source 48V input (See
Appendix B).
The DC power feed options and the high quality and versatility make the
Magnum DS8016-R a good high-availability choice for telcos, ISPs, broadcast equipment,
medical, brokerage firm and financial facilities. In applications where downtime of the
operation is not acceptable, the DS8016-R provides a good Ethernet LAN solution.
