Page 15: Frame Buffering And Latency
Magnum 4K8 Switches are constantly adapting internally to provide maximum network performance with the least dropped packets. 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 16 (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.

Extended Temperature Operation The Magnum 4K8 has been tested for operation at temperatures of –5’C to 55’C. NEBS-certified models have been tested to a greater range per NEBS Level 3 requirements. For details, email mktg@garrettcom.com www GarrettCom com Installation and User Guide... -
Page 18: Applications
Speed characteristic of the 4K8 Switches enables them to inter-connect a series of subnets (one subnet per 4K-Series Switch) in a LAN traffic center. The subnet connections may be via either optional fiber or twisted pair cabling, and may be 100Mbps or 10 Mbps speed and full-or half-duplex mode. - Page 19 Example 2: In another situation similar to Example 1 above, a central Switch is needed to provide for a 8-segment 100Mb fiber Fast Ethernet backbone with switched copper support for 1 high speed local servers and 5 personal network setup for each different departments.

Page 20: 3.0 Installation
The location of a Magnum 4K8 Switch is dependent on the physical layout of the network. Typically the Switch is placed in a central wiring location where groups of network devices need to be connected in order to communicate with each other. These Switches are typically rack mounted in a wiring closet see Section 3.3.2 below), but... -
Page 21: Connecting Ethernet Media
Connecting Ethernet Media The Magnum 4K8 Switches are specifically designed to support all standard Ethernet media types within a single Switch unit. This is accomplished by using a family of Fiber-port Modules (FPMs) which can be individually selected and configured per-port. See Section 2.4 for a description of the FPMs. -
Page 22: Connecting Fiber Optic Sc-Type, "Snap-In
Connecting Twisted Pair (RJ-45,CAT3, CAT5, Unshielded or Shielded) The RJ-45 ports of the Magnum 4K-Series can be connected to the following two media types: 100BASE-TX and 10BASE-T. CAT 5 cables should be used when making 100BASE-TX connections. When the ports are used as 10BASE-T ports, CAT 3 may be used. -
Page 23: Rack-Mounting
Rack-mount installation requires special 19” rack-mounted brackets and screws (included with each 4K8 unit). The brackets attach to the front sides of the Switch, which is then fastened into a standard 19” RETMA rack. The 23” brackets and ETSI brackets are also available (optional) for rack- mounting of Magnum 4K Series Switches. -

Remove front-top chassis above. Step 2. The figure here illustrates the basic layout of an individual FPM card. - Page 27 Step 4. Once FPM cards have been installed, the chassis cover should be replaced. 3.4.3 Removing FPM Cards from Magnum 4K8 Switches To properly remove an FPM card from a 4K8 Switch, follow the 3 steps below. Step 1. Remove chassis cover Caution: Be sure the power cord is unplugged.

Switching Functionality A Magnum 4K-Series provides switched connectivity at Ethernet wire-speed among all of its ports. The Magnum 4K-Series supports10/100Mbs for copper media and 10 or 100Mb separate traffic domain for fiber port to maximize bandwidth utilization and network performance. All ports can communicate to all other ports in a Magnum 4K8, but local traffic on a port will not consume any of the bandwidth on any other port. -

The Magnum 4K-Series Fast Ethernet bonus copper port# 9 can be set for either fixed 100Mb speed or for 10/100 F/H N-way auto-negotiation per the IEEE802.3u standard. - Page 31 When operating in 100Mb half-duplex mode, cable distances and hop-counts may be limited within that collision domain. The Path Delay Value (PDV) bit-times must account for all devices and cable lengths within that domain. For Magnum 4K-Series www GarrettCom com...

Duplex mode. The purpose of flow-control is to reduce the risk of data loss if a long burst of activity causes the switch to save frames until its buffer memory is full. This is most likely to occur when data is moving from a 100Mb port to a 10 Mb port, and the speed difference makes the 10Mb port unable to keep up. -

Chapter 5 for specific return procedures. Product Description An important feature of the Magnum 4K-Series is the use of Fiber- Port Modules (FPMs) for flexible mixed-media connectivity to RJ-45 and fiber media. Since the Magnum 4K-Series Switches have dual-speed capability for copper ports, the fiber-port interfaces are designed to support all standard Ethernet media types at 10 or 100Mps speed. -
