The Magnum DS60s will filter and forward the packets to / from port 6 and the other ports, thereby giving more bandwidth to each domain for maximum network performance. -
Page 11: Magnum Ds60F Ds Hubs Plus, With Fiber Switched Port
Magnum DS50 / DS60s Dual Speed Hubs DS60s are “plug and play” units enclosed in a lightweight, compact, rugged metal enclosure suitable for office, lab and industrial sites. The DS50 / DS60s are available for horizontal or vertical mounting (see Section 3.1). -

(no media converter is required !) and supporting long (up to 40km) fiber cable distances for installation versatility. Port 6 (the fiber port) has an “F - H” user-selectable manual switch. When set in the “F” position, it forces full-duplex mode. When set in the “H” position, it forces half-duplex mode, still at 100Mbps speed. -

10BASE-T port or as a 100BASE- TX port. The speed may depend upon the attached unit’s speed. See section 4.3 for more details about the 10 or 100 switch. This switched port offers great flexibility in connecting the DS60C . . . as an additional 10/100Mb segment . -
Page 14: Ports 1-5: 10/100 Mb/S Shared Ports For Ds50 / Ds60
The up-link switch for Port 1 is located on the left side and enables port 1 to either connect to a user station or to cascade with another hub or switch. See section 4.4 for more details about up-link. -
Page 15: Bridge Logic Between The 10 Mbps And 100Mbps Domains
Up-link Switch for Cascading The unit has an up-link switch located next to Port # 1 of the hub. It enables the port’s cable to cascade to another shared hub or switching hub port. (See Section 4.4 for more details about up-link). -
Page 16: Frame Buffering And Latency
When the Switch detects that its free buffer queue space is low, the Switch sends industry standard (full-duplex only) PAUSE packets out to the devices sending packets to cause “flow control”. - Page 17 (when operating at half-duplex only). When the Switch detects that its free buffer queue space is low, the Switch prevents more frames from entering by forcing a collision signal on all receiving half-duplex ports in order to stop incoming traffic.

Page 19: Applications
Magnum DS50 / DS60s Dual Speed Hubs Applications The Magnum Dual-speed Hub Plus is designed to provide dual speed (10/100Mbps) connectivity. Pictured below, a Magnum DS50 Dual-speed Hubs serves a small office with mixed speed requirements. Some users operate at 100Mbps, and some users and utility devices (such as print servers) run at 10Mbps. - Page 20 Magnum DS50 / DS60s Dual Speed Hubs To add more 10/100Mb stations, another 10/100Mb workgroup can be added using a DS60C hub. By placing the Magnum DS60C Dual-speed Hub Plus in the middle, it acts as a bridge separating the 10Mb and the 100Mb traffic domains and provides each department with full bandwidth.

Magnum DS50 / DS60s Dual Speed Hubs INSTALLATION This chapter provides instructions for installing the Magnum DS50 / DS60 Dual- speed Hub Plus. Locating the Magnum DS50 / DS60 Dual-speed Hubs Plus The location of the Magnum DS50 / DS60 Dual-speed Hub Plus is dependent on the physical layout of the network and the workgroup to be bridge-isolated. -
Page 23: Optional Mounting Methods, Din-Rail And E-Stand
Magnum DS50 / DS60s Dual Speed Hubs Each Magnum DS50 / DS60 Dual-speed Hub Plus is shipped with two mounting brackets (and screws), to allow the unit to be mounted in nearly any desired orientation or position. The brackets are attached to the unit’s case with one of the metal screws for each bracket. -
Page 24: Connecting Twisted Pair (Rj-45, Cat 3 Or Cat 5, Unshielded Or Shielded )
For Port # 1 or 1SW, if the LINK LED is not illuminated, move the switch which has a cross-over or up-link for linking to another hub or Switch. -
Page 25: Connecting Single-Mode Fiber Optic
Magnum DS50 / DS60s Dual Speed Hubs The LINK LED for the fiber connector will illuminate when a proper connection has been established at both ends (and when power is ON in the unit). If LINK is not lit after cable connection, the normal cause is improper cable polarity. Swap the fiber cables at the fiber connector to remedy this situation. -
Page 26: Connections To Nics Which Support Auto-Negotiation, Rj-45 Ports
3.2.5 Connections to NICs which support Auto-Negotiation, RJ-45 ports The copper ports of Magnum DS50 / DS60s will function properly with NICs (Network Interface Cards) which support Auto-Negotiation, and the Fast Link Pulse (FLP) coding for the 100BASE-TX signaling system. When connecting a NIC to a DS50 / DS60, it may be necessary to reload the NIC drivers on the user device if the NIC has been communicating with a protocol other than 100BASE-TX (such as 10BASE-T). - Page 27 Magnum DS50 / DS60s Dual Speed Hubs Each Fast Ethernet device component also has an associated BT delay, which depends on the physical signaling system employed. Table 3.2b shows each Fast Ethernet device component and the associated BT delay. Note that there is only one DTE pair associated with any device-to-device path.
- Page 28 Magnum hubs, 100 is the BT delay for the TX DTE pair, and a safety margin of 0 was used. (Note the internal switch on port 6 does not enter into this calculation of one collision domain’s cable lengths. If used, port 6 of the Magnum DS60C when set to 100Mb has a PDV of 50BT, the same as a NIC or node.).

Full duplex and Auto-negotiation mode at 10 or 100Mbps for the switched copper port can be done through the manual switch underneath the port it controls. Similarly the Fiber switched port at 100Mbps can be set at Full duplex as well as Half-duplex through the manual switch underneath the port it controls. -

Magnum DS50 / DS60s Dual Speed Hubs will be forwarded to the appropriate port, and will not be sent to the other ports where it is not needed. Traffic needed for maintaining the operation of the network (such as occasional multi- cast packets) is forwarded to all ports. -
Page 34: F-H) Manual Switch, Port 6 For Ds60F
After switching from Full fixed to auto-negotiation or vice versa, it is necessary that the unit be powered down and back up to reset the internal buffers of the switch. Even though it is not always required, powering down and up will enable proper packet handling in all cases for both segments of the network. -
