3012 & 3024 Stackable Hubs The Magnum 3000 Stackable Hubs provide 12 or 24 shielded RJ-45 Ethernet ports, plus a configurable bonus ports. SNMP management is available as an option. Users can stack up to 20 units in any combination, normally rack-mounted. The Magnum 3000 series offers many options not typically available in standard 10BASE-T managed stackable hubs. A rear bonus port may be configured with different media--bridge and repeater port options.
Garrett Communications has developed a 48 Volt DC option that is available for the Magnum 3012 and 3024. This is a solution already widely applied in the telecommunications industry and will allow a firm to maintain operations in the event of a power failure. A 48VDC dual-source option is also available. Magnum 3000 Stackable Hubs have also been tested and are NEBS Level 3 Certified.
The Magnum DS880 Stackable Hubs provide eight RJ-45 ports per hub--each port speed-sensing for 100 or 10Mb. Essentially providing two hubs in one, the DS880 enables small- to medium-sized networks to mix 100Mb ports for high-bandwidth applications with economical 10Mb ports. The DS880 stacks of up to 4 units for a maximum of 32 Ethernet ports--each 10/100 dual speed.
New network chip technology enables the Magnum DS880 Dual Speed Hubs to identify and accept either 100Mb or 10Mb signals on a per-port basis. Each port auto-senses and can change from 10Mb to 100Mb at any time without affecting other ports.
GarrettCom has developed a 48 Volt DC option that is available for the Magnum DS880-A and DS880-B. This is a solution already widely applied in the telecommunications industry and will allow a firm to maintain operations in the event of a power failure. A 48VDC dual-source option is also available. Magnum DS880 Dual-Speed Stackable Hubs (Models: DS880-A-NEBS & DS880-B-NEBS) have also been tested and are NEBS Level 3 Certified.
Internal Power Supply (AC, -48VDC, 24VDC). Provides five 10/100Mb hub ports, plus 10 or 100 switched port on DS60s for connection to another Ethernet domain. Fiber port on DS60F may be multi-mode SC, 20km single-mode, or 40km long-reach Plug-and-play operation, for easy installation when adding 100Mb ports to either a 10Mb or a 100Mb Ethernet network. Very low (Class B) EMI. Comes with a durable metal enclosure, table-top or wall mounting. NEBS Compliant
The Magnum 1000 Workgroup Hubs provide an inexpensive, flexible solution to workgroup networking, smoothly connecting into the central network. Bridge-isolation for high performance workgroups is optional on all models. The Magnum 1000 comes in models supporting 8, 16, or 24 front-mounted shielded RJ-45 ports. An additional mixed-media bonus port is available on the rear panel for an optional Port Module. One front panel port is configurable to "uplink" to another hub or concentrator to create stackable hubs.
H5O: 4 RJ-45 ports and 1 up-link; External power source 115 or 230VAC. H80: 8 RJ-45 ports. Expand the number of 10Mb RJ-45 ports in a multi-system environment. Durable metal enclosure. Conformal Coating (optional). DIN-Rail mounting kit (optional).
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.
