1.2 Ordering Information

Magnum DS8016 Dual-Speed Stackable Hubs

Magnum DS8016-A:

auto-sensing for 100Mb or 10Mb operation. Stackable up to three units high,
with all ports in one stack operating as two separate traffic domains, one domain
at 100Mb/s and one domain at 10Mb/s. Includes stacking cable, internal auto­ranging power-supply, cooling fan, and metal brackets for shelf or wall
mounting.

Magnum DS8016-B:

module that bridges the two traffic domains, filtering and selectively forwarding
packets between the 100Mb and the 10Mb domains. Stacks up to two DS8016­A units. One DS8016-B unit stack supports all ports at 100Mb or 10Mb
communicating with each other. The internal switch has 2Mb dynamic store­and-forward packet buffers and 8K node addresses.

Magnum DS8016-E:

Dual-Speed 10/100 Stackable Hub with sixteen RJ-45ports, each

Same as Magnum DS8016-A but includes an internal switch

Same as Magnum DS8016-A but all ports operate at 100Mbps

only(not dual speed-speed). Each port will auto-negotiate with an attached
10/100device for 100Mbps speed and half-duplex mode only. May be used in
DS8016 stacks, same as Model DS8016-A.

Magnum DS8016-R:

Same as Magnum DS8016-B but with all ports on the rear side
and all of the LEDs are on front panel. No stacking. Normally used with 48V
DC dual source power supply, mounted in telco racks.

RMB-23W: Set of two mounting brackets that extend a standard 19” DS8016 hub

for mounting in a 23” -wide telco rack, 1U high.

Magnum DS8016 Dual-Speed Stackable Hubs Installation and User Guide (07/06)

2.2 Product Description - General

Magnum DS8016 Dual-Speed hubs have sixteen RJ-45 ports, each 10/100Mb auto­sensing *. Each port can independently identify (via IEEE 802.3u auto-sensing) and accept
either 100Mb or 10Mb Ethernet signals, adapting to match the best speed of the connected
device. There are two internal traffic domains in Magnum DS8016 hubs, one for the 100Mb
traffic and one for the 10Mb traffic. The 100Mb users share the 100Mb domain’s bandwidth
and the 10Mb users share the 10Mb domain’s bandwidth.

* Note:

the “special 100Mb-only” model DS8016-E is not dual-speed. See Section 2.2.3 below.

Any DS8016 port can connect into either the 100 or the 10Mb traffic domain, and
can also change from one traffic domain to the other at any time without affecting the speed
of other ports. The automatic per-port speed-sensing is continuous (it takes place at LINK
enable, see section 4.2 for details), allowing the connected devices to change speed at any
time without impairing the operation of the other ports and connected devices.

Figure 2.2 a : Magnum DS8016s are functionally both a 10Mb and a 100Mb hub in one

As Magnum DS8016 Dual-Speed units are stacked, the two shared traffic domains
automatically expand to support all of the ports in the stack. Any combination of 10Mb and
100Mb ports, up to the maximum of 48 ports (3 units) in one stack, can be in use at any time.

Some DS8016 models, the Magnum DS8016-B and DS8016-R, include an internal
bridge or switch module which interconnects the 10 Mb and the 100Mb traffic domains. This
enables all users on a DS8016-B or -R hub or a DS8016 stack, whether 100Mb or 10Mb, to
talk to each other. The internal switch of the DS8016’s filters and selectively forwards
packets between the 10Mb and the 100Mb domains, maintaining peak performance in each
domain unaffected by local traffic in the other domain. The internal bridge is self-learning,
with large address table capacity for up to 8K node addresses. As networked nodes are
added or removed or move from one speed domain to the other, the DS8016-B’s (or DS8016­R’s) internal switch automatically keeps track.
