Description
The Magnum
DS80 and DS80F Dual-Speed Personal Hubs extend the very popular Personal
Hub line with a new 10/100 Personal
Hub with a built-in filter-and-forward Switch for connecting both 10Mb
and 100Mb users. The DS80F also offers two switched 100Mb ports--one
of which may be full-duplex fiber-ST or fiber-SC--multi-mode or single-mode.
The DS80 family offers the performance of a 100Mb switched fiber link
upstream with the convenience of dual-speed 10/100 copper ports for
the workplace LAN, all in one compact unit about the size of a paperback
book.
The built-in filter-and-forward switch for the hub ports
enables communication between the 10Mb and the 100Mb domains. This
switch has an auto-learning 8K address table and 1MB dynamically allocated
packet buffer.
Overview
- Compact office-hub
packaging brings 100Mb Fiber backbone connectivity to the workplace.
No media converter needed.
- Top-mounted LEDs
make status monitoring easy.
- Provides six 10/100Mb
dual-speed RJ-45 ports for users, one 10/100Mb switched RJ-45 port
for a server or for users, and one switched 100Mb Fiber FDX "backbone" port.
- 100Mb Ethernet
Fiber connectors maybe multi-mode SC, ST, MTRJ, or single-mode
(either 20km or 40km "long-haul") SC type.
- 8-port all copper
model available
- Comes with a durable
metal enclosure, metal mounting clips, and external power supply
for either 115vac or 230vac power.
- Internal cooling
design uses the metal case as a heat sink, enabling operation to
50°C ambient.
| DS880-A |
Dual Speed 10/100 Stackable Hub with eight RJ-45
ports, each auto-sensing for 100Mb or 10Mb operation. Stackable
up to four units high. Includes stacking cable, internal
auto-ranging power supply, cooling fan, and metal brackets for
rack-mounting. |
| DS880-B |
Same as Magnum DS880-A, but includes an internal switch that
bridges the two traffic domains, filtering and selectively forwarding
packets between the 100Mb and the 10Mb domains, filtering and selectively
forwarding packets between the 100Mb and the 10Mb domains. Stack
with up to three DS880-A units. One DS880-B unit per stack
supports all ports at 100Mb and 10Mb communicating with each other. The
internal switch has 2MB dynamic store-and-forward packet buffers
and 8K node addresses, self-learning. |
| DS80F-MSC-d, i* |
Dual Speed 10/100 8-port office hub with
one full-duplex 100Mb switched fiber port (multi-mode SC-Type connector),
one "N-way" switched RJ-45 port, and six half-duplex
10/100 auto-negotiating ports. Includes store-and-forwarding
switching that filters and forwards data moving between the two
switch ports, and among the 10/100 user ports. The internal
switch has 8K node addresses and 512KB packet buffers. External
power supply, metal brackets for mounting. |
| DS80F-MST-d, i* |
Same as DS80F-MSC but with multi-mode ST-type fiber port
connector. |
| DS80F-MTRJ-d,I* |
Same as DS80F-MSC but with multi-mode MTRJ-type fiber
port connector. |
| DS80F-SSC-d, i* |
Same as DS80F-MSC but with 20km single-mode SC-type fiber
port connector. |
| DS80F-SSCL-d, i* |
Same as DS80F-SSC but with "40km long reach" single-mode
SC fiber connector. |
| DS80C-d, i* |
Dual Speed 10/100 8-port "copper" office hub with two
10/100 N-way switched ports and six half-duplex 10/100 auto-negotiating
ports. Includes store-and forward switching that filters
and forwards data moving between the two switched ports, and among
the 10/100 user ports. The internal switch has 8K node
addresses and 512KB packet buffers. External power supply,
metal brackets for mounting, |
