Configuring the SyncServer

Recommended Tasks
GPS antennas not rated for 12 VDC power may be damaged if connected to the SyncServer.
1. Mount the standard L1 GPS antenna (supplied) in a locationthat offers good visibilityof GPS satellites, such as a rooftop or outdoor antenna mast with wide open views of the skyand horizon. Avoidobstructions and sources of Radio FrequencyInterference. Observe building codes and regulations. Also see Using GPS (on page 140) and WARNING: GPS Antenna (on page 132).
a. Note: For the SyncServer 350i, which doesn't have a GPS receiver, connect an
IRIG signal to the IRIG In connector on the rear panel and skip references to GPS and antennas in the rest of this procedure.
2. On the rear panel:
n
Connect the GPS antenna cable (supplied) to the GPS Ant connector.
n
Connect LAN1 and any of the other network ports to the network.
997-01520-02 Rev. F1.......................................................................... Page 13
S300, S350 and S350i Quick Start Guide
n Consult Warnings and Cautions (on page 131) for safety informationregarding
grounding and power.
n Connect the power and turn the power switch on.

4.
Go to the SyncServer Login page by entering the LAN1 IP addressas the URL in Internet Explorer.
5. Log in. The user name is "admin". The password is "symmetricom".
6.
Configure the SyncServer using WIZARDS - 1st Setup. Select the following options:
n "Configure Password Recovery" (Ask the IT department for the IP address of the
SMTP server).
n "Send test mail when finished" n "Set Local Time Zone"
7.
Configure the remaining network ports using NETWORK - Ethernet.
n Assignstatic IP addresses. n Protect LAN1 and the other ports from unauthorized IP addresses or address
ranges using the Allowed Access feature.
8. Configure the NTP clients on your network with the IP address(es) of the SyncServer's network ports.
The SyncServer is providing synchronized time to the network when the SYNC LED (front panel) is orange or green.
Optional Tasks
In the web interface:
n Connect any other Input References to the rear panel and configure them usingthe
pages under the REFERENCES section.
n
Use the NTP – Config page to synchronize the SyncServer with any other NTP servers.
n
Use WIZARDS - SNMP to set up alarm notification by SNMP.
n
Use SERVICES - Email to set up alarm notification by email.
n
When the SyncServer is completelyconfigured, use WIZARDS - Backup to save a backup file of the configuration to a safe location. Write the location of the backup file on this prin­ted document and store it in a location that is easy to find.

Product Overview

The SyncServer Network Time Server offers the following protocolsfor synchronizing equip­ment over a network:
n NTP n PTP Grand Master (option) n SNTP n Time (TCP and UDP versions) n Daytime (TCP and UDP versions) n Sysplex Output (dedicated port)
These protocols are capable of synchronizing computers, servers, and networking equip­ment on an enterprise-scale network to within milliseconds of officialUTC time. This degree of synchronization is desirable for precise time-stamping of events and data correlation.

The State of the physical network port device (not of the connection). An "Up Arrow" meansit is "running". A "Down Arrow" means it is "not running".
Management Port DNS Servers: Both user-entered and DHCP-assignedDNS Server addresses that are available from the LAN1 port.
The SyncServer requires at least one valid DNS server to resolve domain names, which may be used in NTP associations, and SMTP gateways (email). Without a DNS server, any function that uses a DNS name instead of an IP address may be affected. These can include NTP, password recovery, and email notification of alarms.

STATUS - Timing

Hardware Clock Status
Current Sync Source: The Input Reference currently used by the Hardware Clock. Consult the TIMING - HW Clock topic for more information.
Hardware Clock Time: The time according to the Hardware Clock. Hardware Clock Status: "Locked" means the Hardware Clockis synchronized to one of its ref-
erences, or to the internal oscillator in "Holdover". "Unlocked" means the Hardware Clock doesn't have an Input Referenceand the Holdover period has expired. Also see TIMING - HW Clock (on page 61) and TIMING - Holdover (on page 63).
Oscillator Type: The type of the oscillator installed in the Hardware Clockfor operation and hol­dover.
For each of the following Input Status lines, "Locked"means that the reference is valid and can be selected by the Hardware Clock. "Unlocked" meansthe reference is not valid, and is therefore not available for use by the Hardware Clock. Also see TIMING - HW Clock (on page 61) to arrange the priorityof the Input References.
Some of these references are optionsor are only available in specific SyncServer models. (Consult Product Overview (on page 17) for more information about featuresand models):

STATUS - GPS

GPS Receiver Operation
This page displays the status of the GPS Receiver.
Receiver Description: "GPS" indicatesthe presenceof a 12-channel GPS receiver. Receiver Status:
1
n Receiver Down: The Hardware Clock can't communicate with the receiver. n Unknown Mode: An undefined mode of the GPS receiver. n Acquiring Signal: The receiver is attempting to track a GPS signal.
1
The SyncServer S350i does not include a GPS receiver.

STATUS - GPS
n Bad Geometry: The geometry of the tracked satellitesis unsatisfactory for a position solu-
tion.
n Propagate Mode: A position estimation mode used in highly dynamic environments. n 2d Solution: The receiver is able to perform position fixes for latitude and longitude but
does not have enough satellites for altitude.
n 3d Solution: The receiver is now able to perform position fixes for latitude, longitude and
altitude.
n Position Hold: Positionfixes are no longer attempted, and the surveyed or user-entered
position is used.
n Time Valid: The receiver has valid timinginformation from GPS satellites (including GPS-
UTC Offset and Leap Indicator). If the GPS receiver and antenna are set up correctly, the receiver status should eventuallyreach and remain in this state.
Mode:
n Survey: The receiver is surveying and averaging its position. When it has finished sur-
veying, the receiver switches to Position Hold mode. Survey mode and PositionHold mode are appropriate for static applications, such as a typicalserver room environment. This is the default mode when the SyncServer starts.
n Dynamic: The GPS receiver surveys continuously to determine its position and doesn't
switch to another mode. This mode must be initiated by a user, and is appropriatefor mobile applications such as ships, land vehicles, and aircraft. The degree of accuracy this mode offers is fine for NTP time over networks, but is less than optimal for the timing out­puts available on some SyncServer models.
n Position Hold: The GPS receiver has completed Survey mode and switched to this
mode, or the user has manuallyentered a positionand "forced"it into this mode. The accuracy and stability of the SyncServer's timing outputs are optimalwhen the receiver has its exact position and is in this mode.
Antenna Cable Delay (nS):
The user-configured value (on the REFERENCES - GPS page) to compensate for GPS signal propagation from the antenna along the length of the cable to the receiver.
Antenna Status: The GPS receiver supplies power to the GPS antenna through the antenna cable. It also
monitors the current to that circuit to detect open or short circuits.
n Good: The current to the GPS antenna and cable is normal. n Open:The current is too low. The GPS antenna or cableis probably disconnected or
broken. Some splitters may cause this condition as well.
n Short: The current is too high. The GPS antenna or cable probably has a short circuit.
Position: The latitude and longitude of the GPS antenna in degrees, minutes, and fractional seconds. Referenced to WGS-84.
Altitude: The altitude of the antenna in meters. Referenced to WGS-84. Satellites: The list of GPS satellites visible to the receiver:
n Sat Number: The GPS satellite's Satellite Vehicle (SV) number, a unique identification
number
n Signal: The relative strengthof the GPS signal (dBW = decibels relative to 1 Watt).

n Status: "Current" means that the receiver is usingthe GPS signal in its timing solution.
"Tracked" means the receiver is trackingthe signal, but isn't using it in the timingsolution.

WARNING:GPSPositionandAltitude

GPS position and altitude are for timingpurposes only. They are not intendedfor navigation or other critical applications.
AVERTISSEMENT : La position et l'altitude de GPS sont seulement pour la syn­chronization. Ellesne sont pas prévues pour la navigation ou d'autres situations critiques (situations de la vie-ou-mort).

STATUS - NTP

NTPDaemonStatus

This page displays the status of the NTP daemon. Many of the fieldsbelow are based on the NTP Packet (on page 198). Also see http://www.ntp.org.
system peer: The IP address of the clocksource. The sourceis selected by the NTP dae­mon that is most likely to provide the best timing information based on: stratum, distance, dis­persion and confidence interval. The system peer identified as "SYMM_TE(0)" is the local SyncServer Hardware Clock. Also see Hardware Clock (on page 196).
system peer mode: The relationship of the SyncServer to a system peer, usually a "client". Depending the configuration, the mode can be:
n Client: A host operating in this mode sends periodic messages regardlessof the reach-
ability state or stratum of its peer. By operating in this mode the host, usually a LAN work­station, announcesits willingnessto be synchronized by, but not to synchronize the peer.
n Symmetric Active: A host operating in this mode sends periodic messages regardless
of the reachabilitystate or stratum of its peer. By operating in this mode the host announces its willingness to synchronize and be synchronized by the peer.
n Symmetric Passive: This type of association is ordinarilycreated upon arrivalof a mes-
sage from a peer operating in the symmetricactive mode and persists onlyas long as the peer is reachable and operating at a stratum level less than or equal to the host; oth­erwise, the association is dissolved. However, the association will always persist until at least one message has been sent in reply. By operating in this mode the host announces its willingness to synchronize and be synchronized by the peer.
A host operatingin client mode (a workstation, for example) occasionally sendsan NTP mes­sage to a host operating in server mode (the SyncServer), perhaps right after rebooting and at periodic intervals thereafter. The server responds by simply interchanging addresses and ports, filling in the required time information and returningthe message to the client. Servers need retain no state information between client requests, while clientsare free to manage the intervalsbetween sending NTP messages to suit local conditions.
In the symmetric modes, the client/server distinction (almost) disappears. Symmetric passive mode is intendedfor use by time servers operating near the root nodes (lowest stratum) of the synchronization subnet and with a relativelylarge number of peers on an intermittent

STATUS - NTP
basis. In this mode the identity of the peer need not be known in advance, since the asso­ciation with its state variables is created only when an NTP message arrives. Furthermore, the state storage can be reused when the peer becomes unreachable or is operating at a higher stratum level and thus ineligible as a synchronization source.
Symmetric active mode is intendedfor use by time servers operating near the end nodes (highest stratum) of the synchronization subnet. Reliable time service can usuallybe main­tained with two peers at the next lower stratum level and one peer at the same stratum level, so the rate of ongoing polls is usually not significant, even when connectivity is lost and error messages are being returned for every poll.
leap indicator (LI):
The Leap Indicator (LI) is a two-bit binary number in the NTP packet header that provides the following information:
n Advance warning that a leap second adjustment will be made to the UTC timescale at the
end of the current day. Leap secondsare events mandated by the world time authority (BIPM) in order to synchronize the UTC time scale with the earth's rotation.
n Whether the NTP daemon is synchronized to a timing reference. The settings on the
NTP - Prefs (on page 50) page affect LI behavior.
LI Value Meaning
00 0 No warning. 01 1 Leapsecondinsertion: Last minute of the day has 61 seconds.
10 2 Leapseconddeletion: Last minute of the day has 59 seconds. 11 3 Alarm condition (Not synchronized)
When the SyncServer or NTP daemon is started or restarted, the leap indicator is set to "11", the alarm condition. This alarm condition makes it possible for NTP clients to recognizethat an NTP server (the SyncServer) is present, but that it has yet to validate its time from its time sources. Once the SyncServer finds a valid source of time and sets its clock, it sets the leap indicator to an appropriate value. The NTP Leap Change Alarm on the ADMIN - Alarms page can be configured to generate an alarm and send notificationseach time the leap indic­ator changes state.
stratum:
This is an eight-bit integer that indicates the position of an NTP node within an NTP timing hierarchy. It is calculated by adding 1 to the stratum of the NTP system peer.
For the SyncServer, the stratum valuesare defined as follows:
Stratum Definition
0 Hardware Clock when locked. 1 Primary server 2-15 Secondary server 16-255 Unsynchronized, unreachable.
For example, the SyncServer is:
997-01520-02 Rev. F1.......................................................................... Page 29
Web Interface
n stratum 1 when the Hardware Clock (stratum0) is synchronized to an input reference, in
holdover mode, or in freerun mode.
n stratum 2 through 15 when it is synchronized to a remote NTP server. n stratum 16 when it is unsynchronized, indicating that it is searchingfor a valid source of
timing information. The settingson the NTP - Prefs (on page 50) page affect stratum behavior. precision: This is a signed integer indicating the precision of the selected peer clock, in
seconds to the nearest power of two. A typicalvalue is -18 for a Hardware Clock where the uppermost 18 bits of the time stamp fractional component have value, indicating a precision in the microsecond range.
root distance (also root delay): This is a measure of the total round trip delay to the root of the synchronization tree. A typical value for a SyncServer operatingat stratum 1 would be 0 since the SyncServer is a root of the synchronization tree For other stratum levels, an appro­priate valueis displayed. Depending on clock skew and dispersion, this value could be pos­itive or negative.
root dispersion: This is a signed fixed-point number indicating the maximum error relative to the primary reference source at the root of the synchronization subnet, in seconds. Only positive values greater than zero are possible.
reference ID: This is a four-byte field used to identifythe reference clock source. At ini­tialization, while the stratum is 16, this field shows the progression of the NTP clock PLL. The field will start with a value of INIT (may be displayed as 73.78.73.84, the ASCII decimalval­ues). Once a peer has been selected, the clock may be stepped, in which case the reference ID field will change to STEP (or 83.84.69.80). Once the PLL is locked, the stratum will be updatedand the reference ID will identify the selected peer. In the case of a SyncServer operating at stratum 1, the reference ID will displaythe sourcefor the local timing reference (e.g., GPS1, IRIG, FREE). In the case where the selected peer is another NTP server, the reference ID will display the IP addressof the server or a hash unique to the association between the SyncServer and the remote server.
reference time (also reference timestamp): The time when the SyncServer last received an update from the selected peer. Represented using time stamp format in local time. If the local clock has never been synchronized, the valueis zero. A time stamp of zero corresponds to a local time of Thu, Feb 7 2036 6:28:16.000. This value is typically updatedevery16 seconds for a locally attached hardware reference (e.g., GPS, IRIG) and in an interval of 64­1024 seconds for a readily accessible remote NTP server.
system flags: These flagsdefine the configured behavior NTP daemon running on the Syn­cServer. The definitionof the variablesis provided.
n kernel: The NTP daemon is enabled for the precision-time kernelsupport for the ntp_adj-
time() system call.
n monitor: The NTP daemon is enabled its monitoring facility. n ntp: Enables the server to adjust its local clockby means of NTP. n stats: The NTP daemon is enabled itsstatistics facility. n auth: The NTP daemonis enabled itsauthentication facility.
