shipping container if possible. Refer to Section 5, Troubleshooting, for specific return
procedures.

2.2 Product Description - Magnum 500-Series Switching Hubs

The Magnum 500-Series Switching Hubs provide 8-port switching services to
enhance the performance of 10Mb Ethernet networks by segmenting the network traffic.
They may be used with existing Cat 3 cabling and shared 10b Ethernet hubs. On models
528 and 528F, there are two Fast Ethernet switched ports additionally that provide
100Mb switching services for high speed network connections. Full speed is maintained
across all ports, even when handling the smallest 64-byte frames.

All 10Mb ports in both units can auto-negotiate to either half- or full-duplex
mode. The copper Fast Ethernet ports on Model 528 & 528F are normally set for 100Mb
with manual selection of F/H duplex, but may be optionally set for auto-negotiation.

Magnum 500-Series Switching Hubs Installation and User Guide (08/98)

Designed for use in departments with multiple workgroups, in remote offices
and in network traffic centers, the Magnum 500-Series switches are easy to install and
use. Addresses of attached nodes are automatically learned and maintained, adapting the
switching services to network changes and expansions. The Magnum 500s provide high
performance plug-and-play operation in a compact package.

Figure 2.2a: Front view Magnum 508, 528 and 528F Switching Hubs

Magnum 500-Series switching hubs are equipped with eight shielded RJ-45
ports for shielded and unshielded 10BASE-T connections. Magnum 528 switching hubs
also have two shielded RJ-45 Fast Ethernet ports for 100BASE-TX connection. Both
units include a up-link switch for crossover connection located next to 10Mb Port # 8.
Each 10Mb RJ-45 connector has two LED’s, one to indicate LK/RX (LINK / Receive)
activity and the other (FDX) for indicating full-duplex mode.

On Magnum 528 and 528F models, the 100Mb activity LEDs and the LINK
LEDs are located in the copper Fast Ethernet ports. Other LEDs indicate when auto­negotiation (copper only) is internally selected, that operating speed is 10Mb or 100Mb,
and when the operating mode is full-duplex. Magnum 528 and 528F models also have
two full/half (F/H) switches for the two 100Mb ports for manual selection of the full- or
half-duplex mode when auto-negotiation is not selected. All connectors, switches and
LED’s are located on the front panel, with the AC power connector located at the rear.

Figure 2.2.2: two@100Mb copper ports (528 model), 1@100Mb copper and
1@100Mb fiber ports (528F models), and 8@10Mb ports

All Magnum 500-Series Switching Hubs provide eight 10Mb switched ports.
All 10Mb switched ports are independently auto-negotiating for selecting to operate in
full-duplex mode, and will independently default to half-duplex mode when the 10Mb
device at the other end is half-duplex or is not an auto-negotiating device.

The two Fast Ethernet switched ports on the Magnum 528 and 528F normally
are set (by factory default) to operate at fixed 100Mb speed for guaranteed high-speed
performance. In this case, each of these two ports will run at 100Mbps at all times. The
user may select full- or half-duplex mode per-port with a manual switch for flexibility to
adapt to any type of Fast Ethernet devices. The Full / Half-duplex manual switches are
located on the front panel next to their corresponding Fast Ethernet ports.

For operation in Fast Ethernet auto-negotiating mode (copper only), internal
jumpers must be set. The “AUTO” LED will then be lit to show that auto-negotiation is
in operation. See Sections 4.4 and 3.4 for additional details.

On Magnum 528 units, there are three LED’s for each Fast Ethernet port. One
indicates operation at 100Mb speed when lit, one indicates operation at 10Mb speed
when lit (possible when auto-negotiation is enabled only, copper ports), and one is lit to
indicate full-duplex operation (when it is OFF, operation is half-duplex). A twisted pair
or fiber cable must be connected to each 100Mb port and a proper link (LK lit) must be
made with the device at the other end of the cable in order for these LEDs to provide
valid indications of operating conditions.
