Page 10: Chapter 2 Hardware Installation
Chapter 2 Hardware Installation SNMP Media Converters can be installed as either managed or unmanaged devices. Hardware installation information for both is included in this chapter. If the SNMP Media Converter is to be a managed device, refer to the SNMP Software Installation Manual (included with an SNMP Master Module) for information regarding software installation. -
Page 11: Installing An Unmanaged Snmp Media Converter
Power supplies are available in 90/240 VAC or -48 VDC power versions. If the chassis is shipped with only one power supply module, a blank bracket covers the slot where a second power supply module can be installed. To install a power supply module in an SNMP Telco Chassis or SNMP 6-Slot Chassis, remove the blank bracket covering the slot where the module is to be installed by removing the screws located closest to the outside edges of the bracket. -
Page 12: Installing A Managed Snmp Media Converter
Installing a Managed SNMP Media Converter The hardware installation for a managed SNMP Media Converter is similar to that of an unmanaged SNMP Media Converter, except that each managed SNMP Media Converter has to either have an SNMP Master or Slave Module installed. Slave SNMP Media Converters must be connected to a Master SNMP Media Converter. -
Page 13: Connecting A Master Snmp Media Converter
The SNMP Master Module is connected to the LAN via an external 10Base-T hub connection. The SNMP Slave Module provides an SNMP management uplink to the SNMP Master Module. Once each Slave is installed, it has to be connected to the Master SNMP Media Converter (either directly or through another Slave connected to a Master). -
Page 14: Connecting A Slave Snmp Media Converter
Connecting a Slave SNMP Media Converter Slave SNMP Media Converters are connected to a Master SNMP Media Converter via a straight-through, twisted pair cable. Master and Slave SNMP Media Converters communicate via an RS-485 connection. Multiple Slave SNMP Media Converters are connected in a daisy-chain configuration. -

the near side of the fiber segment nor the twisted pair segment will be affected. Figure 2.9 Application with LinkLoss and FiberAlert Disabled As shown in Figure 2.10, using the same application, if LinkLoss is enabled on the near side and FiberAlert is enabled on the far side, the near side will be notified of any fiber link faults on the far side, thus eliminating “silent failures.”... - Page 18 problem resides with the fiber segment. If LinkLoss is disabled and the connection between the SNMP Media Converter and the hub/switch is NOT reestablished, the failure resides with the twisted pair segment. When a failure occurs, check that cables are properly connected.

Page 20: Fiber Optic Cleaning Guidelines
Fiber Optic Cleaning Guidelines Fiber Optic transmitters and receivers are extremely susceptible to contamination by particles of dirt or dust, which can obstruct the optic path and cause performance degradation. Good system performance requires clean optics and connector ferrules. 1) Use fiber patch cords (or connectors, if you terminate your own fiber) only from a reputable supplier;... -
