Every log line, badge swipe, camera frame and database commit on your network carries a timestamp. If that timestamp comes from a public internet source, you are trusting a server you do not control, reached through a firewall port you had to open. This bundle replaces that arrangement with a GPS reference of your own.

It is everything needed to stand up a stratum 1 time source in one order: the Bodet Netsilon 7 time server, the GPS antenna with its 20 m (65 ft) cable already in the box, and the surge protector Bodet specifies between the two.

What's in the box

• Bodet Netsilon 7 NTP time server, AC model (Bodet ref. 907 900). 1U 19-inch rack chassis, fanless, TCXO oscillator, four option-card slots.
• Bodet GPS synchronisation antenna with 20 m / 65 ft cable (Bodet ref. 907 047). IP67 outdoor dome, supplied with its cable, mounting bracket and installation manual.
• Bodet surge protector for GPS antenna (Bodet ref. 907 052). Two DIN-rail modules: one for the power pair, one for the data pair.
• Installation manuals for each item.

Why a bundle?

With a bundle you you get a stratum 1 time source that is complete the day it lands: the server, the reference, and the protection between them, chosen to work together.

1. Everything you need, nothing you don't. Time server, GPS antenna, 20 m of cable and the surge protector — the four things it takes to put your own stratum 1 reference in a rack. No fifth item to be talked into, and no second order.
2. The component decisions are already made. The Netsilon 7 accessory list runs to four antennas, four power variants and six option cards. This is the combination that fits the large majority of Canadian installations: GPS, AC power, 1U, one Ethernet port, cable in the box. One decision instead of eleven.
3. Protected the way Bodet specifies. The installation manual calls for a DIN-rail protector indoors at the cable entry, bonded to the same ground as the server. It ships with the bundle, so the protection is part of the design rather than something added after the first storm.
4. It commissions in one visit. Nothing arrives on three different dates, and nothing sits in a rack waiting for a part to show up. Rack it, mount the antenna, land the cable through the protector, and it is answering NTP the same afternoon.

Netsilon 7 time server: specifications

GPS antenna, ref. 907 047

The same antenna body is available for other constellations: GPS + GLONASS (907 034), GLONASS (907 044) or Galileo (907 043).

Surge protector, ref. 907 052

Where it fits

• Municipal and public safety
• Healthcare
• Utilities and industrial
• Education
• Data centre and enterprise IT

What you supply

• 1U of rack space and a standard IEC power outlet
• An outdoor location with a clear view of the sky — a wall, a flat surface, or a horizontal or vertical pole 
• A 35 mm DIN rail indoors, close to the point where the antenna cable enters the building
• An earth conductor of at least 4 mm² bonding that DIN rail to the same grounding network as the time server
• Mounting screws for the antenna bracket — four Ø 8 mm holes.

Options and upgrades

All of the following are quotable. Contact sales.

• Power variants: DC (907 901), AC+DC redundant (907 902), AC+AC redundant (907 903)
• Other antennas: GPS + GLONASS (907 034) where a second constellation is required, or GLONASS (907 044) and Galileo (907 043) on their own
• Option cards: network RJ45 (907 920), network SFP (907 921), ASCII (907 926), current loop/dry contact (907 944)
• Redundancy: a second Netsilon 7, peered over NTP

Questions we get asked

Do I really need the surge protector?
In practice, yes. The antenna sits outdoors, usually at the highest point on the building, which makes its cable a direct route into your equipment room. Bodet's installation manual specifies the protector indoors at the cable entry, with the DIN rail bonded to the same ground as the server. Leaving it out puts the appliance behind an unprotected outdoor run.

Is 20 m of cable enough?
It covers most installations where the equipment room sits below or near the antenna position. Longer runs are supported — Bodet rates the link to 300 m at 12 V and 700 m at 20 V — but only the first 20 m is supplied. Anything past that can be purchased separately. Measure the real route, including vertical drops and conduit bends, before ordering. If it is over 20 m, tell us and we will spec the cable with it.

How many devices can one Netsilon 7 serve?
Bodet rates it at 7,000 NTP requests per second across all Ethernet ports, and roughly 32,000 typical clients. For almost every enterprise, campus or municipal network, one server answers the capacity question. A second server is a redundancy decision, not a capacity one.

Does it do PTP?
The Netsilon 7 is an NTP server. If you need IEEE 1588 PTP, that is a different product. Tell us what you are synchronizing and we will scope it properly.

What happens if the GPS signal drops?
The server holds over on its internal TCXO oscillator. Bodet specifies 5 ms of drift after 24 hours of holdover, following two weeks of GPS synchronization at constant temperature. Loss of the reference raises an alarm by SNMP trap, syslog, email or relay contact, so you find out before anyone else does.

Will you install it?
Yes, we have a number of installation partners we can dispatch to handle installation and commissioning. Contact sales for a scoped quote.

Can we buy on a purchase order?
Yes. Contact sales and we will issue a formal quote and set up terms.
