SYNC-SWITCH - MANUAL 6 Summary This manual provides to the user of the apparatus SYNC-SWITCH all the information necessary for proper operation. The information include the normal installation procedures and any data on the maintenance and programming in order to facilitate interventions in the field.
SYNC-SWITCH - MANUAL 7 Front View The front panel appears as in the following figure. At the bottom right there are two rows of status LEDs. Rear View The figure below shows the back of SYNC-SWITCH with the positions of the connectors and their electrical wiring. TNC GPS Antenna 10/100/1000 RJ45 Connectors 95 – 240 VAC PSU Gigabit SFP Connectors BNC 10 MHz OUT BNC PPS OUT SYNC-SWITCH does not provide any supply switch.
SYNC-SWITCH - MANUAL 8 Main Operation The main purpose of the SYNC-SWITCH is to act as a Gigabit Switch (copper and fiber) and to timestamp PTPv2 packets. It also implements many Carrier Grade Ethernet features that are briefly illustrated in the following paragraphs. In order to access the WEB interface is sufficient to open the page http://192.168.200.
SYNC-SWITCH - MANUAL 9 SFP transceivers are hot-swappable. You can remove them from and insert them without having to power down the Switch. Inserting an SFP Transceiver 1. Hold the transceiver so that the fiber connector is toward you and the product label is visible 2. Gently slide the transceiver into the SFP slot until it clicks into place 3. Remove the plastic protective cover, if fitted 4. Connect the fiber cable 5.
SYNC-SWITCH - MANUAL 10 Configuration The Configuration panel allows to modify settings related to the device behaviour as the port settings, speed, duplex, synchronous clocking reference, and others. System The switch system information is provided here. System Contact The textual identification of the contact person for this managed node, together with information on how to contact this person. The allowed string length is 0 to 255, and the allowed content is the ASCII characters from 32 to 126.
SYNC-SWITCH - MANUAL 11 IP Router Provide the IP address of the router in dotted decimal notation. VLAN ID Provide the managed VLAN ID. The allowed range is 1 to 4095. SNTP Server Provide the IP address of the SNTP Server in dotted decimal notation. Ports This is the page that has to be used in order to configure the port settings such as speed and duplex. Please note that SFP ports can operate to 2.
SYNC-SWITCH - MANUAL 12 100-FX_AMS - Port in AMS mode with SFP preferred. SFP port in 100-FX speed. Cu port in Auto mode. 1000-X - SFP port in 1000-X speed. Cu port disabled. 1000-X_AMS - Port in AMS mode with SFP preferred. SFP port in 1000-X speed. Cu port in Auto mode. Auto Media Select (AMS) is used for dual media ports (ports supporting both copper (cu) and fiber (SFP) cables. AMS automatically determines if a SFP or a CU cable is inserted and switches to the corresponding media.
SYNC-SWITCH - MANUAL 13 Enumerates the various ports with the corresponding SSM value. Switch Mode Allows to automatically choose the reference source based on link quality or to always stick on a particular port. OCXO Permits to fine tune the voltage reference of the internal high-stability oscillator. Antenna Green if a GPS Antenna is connected. PPS Status Green if the PPS is being correctly reconstructed. Usually at least 4 satellites are needed.
SYNC-SWITCH - MANUAL 14 Role Enables or disables the IEEE 1588 functionality. Currently only end-to-end transparent clock and master clock functionality is supported. Profile Selects the PTP profile between DEFAULT, TELECOM, POWER and CUSTOM. Please note that the following settings may be only changed when using the CUSTOM profile. Sync Interval Selects the Sync interval time (in power of 2). Announce Interval Selects the Announce interval time (in power of 2).
SYNC-SWITCH - MANUAL 15 Encapsulation Selects the encapsulation to be used to transport PTP packets. DSCP Value Allows to change the DSCP value of outgoing PTP packets. Enabled Enables or disables VLAN usage for PTP packets. Priority Specifies the priority of outgoing VLAN tagged frames. ID Specifies the VLAN ID to be used.
SYNC-SWITCH - MANUAL 16 Clock quality level indication is carried via an Ethernet Synchronization Messaging Channel (ESMC) protocol running over the synchronous Ethernet link. • A “heart-beat” message is used to provide a continuous indication of the SSM clock quality level every second. • An event message with the new SSM value is generated immediately. If no SSM messages are received after a five second period the SSM value is set to DNU (Do Not Use).
SYNC-SWITCH - MANUAL 17 In order to check that the Transparent Clock feature is properly working is possible to analyze the Ethernet traffic and verify that the correction field of the PTP Event messages is being correctly updated. When Synchronous Ethernet and transparent clock feature are both enabled the PPS reconstruction from PTP slaves achieves a great performance boost due to the reduced Packet Delay Variation.
SYNC-SWITCH - MANUAL 18 Firmware Upgrade Firmware may be upgraded on the fly by means of providing a new .dat file via network. The overall procedure may take up to 5 minutes. The Software Upload page facilitates an update of the firmware controlling the switch. Browse to the location of a software image and click Upload. After the software image is uploaded, a page announces that the firmware update is initiated. After a few minutes, the firmware is updated and the switch restarts.
