1111 Introduction

IntroductionIntroduction

Introduction

This document is the User’s Manual for the EPSILON Switch and Amplifier System E17 and the
EPSILON Switch and Amplifier System E36. (Unless otherwise indicated, details contained
herein apply to both models.)

The SAS-E achieves redundant Time & Frequency source monitoring with intelligent and
automatic switching. It amplifies signals from the selected source and offers a large quantity of
output channels. The SAS-E receives, and monitors continuously, signals from 1 or 2 external
clocks:

• Frequency sine wave signal (from 1 MHz up to 16 MHz)

• 1 pulse per second time synchronization (TTL/50Ω)

• Time Of Day message (RS232C serial line)

• External signals

• External clock status (relay contact)

Monitoring results (lost signal and minimal period detection) are reported to the user through
dedicated LEDs and through an Ethernet port. When 2 external clocks are connected, the
SAS-E offers a powerful redundant function by selecting, automatically, the better source. This
automatic selection may be by-passed by the user to allow maintenance or for single clock
operation.

In all cases, the distributed signals — Frequency, 1 Pulse Per Second (PPS), Time of Day
(ToD) — are issued from the same source clock. In automatic mode, when the current selected
source is detected faulty, the SAS-E switches all the distributed signals to the other source. An
Ethernet port allows managing and controlling the SAS-E through embedded SNMP protocol
and/or web server.

The SAS-E is available in two heights to adapt the output capacity to the user’s requirements:

SAS17E — 1u High Version:

8 x frequency outputs, 8 x 1PPS outputs, 2 x ToD outputs, 2 x external signals.

SAS36E — 2u High Version:

16 x frequency outputs, 16 x 1PPS outputs, 2 x ToD outputs, 2 x external signals.

Installation

The unit can be used by itself or mounted in a rack. Leave free space of a few centimeters
under the unit, in order to facilitate natural air flow from the bottom to the top of the SAS-E.

•

Connecting cables for signals and power supply should be secured to locks provided for

this purpose.

•

Connect a ground lead from the Earth pin on the SAS0E back panel to the frame of the

rack.

3.1 Powering Up

Powering UpPowering Up

Powering Up

The SAS-E can be powered from an AC source, from a DC source, or from both.

For full redundancy, connect the DC power cables to the VDC connector and the AC power
cable to the AC connector. Check the polarity of the power signal before connecting it (refer to

DC Power Supply

and to the back panel labels for the pin-out). Priority is given to AC input.

Power-up is immediate when connecting DC power with the cable, while AC power must be
switched on.

During power-up, check the initialization sequence process (OS boot) on the front panel. All of
the LEDs should be activated. This process may take about two minutes.

3.2 Network Connection

Network ConnectionNetwork Connection

Network Connection

The factory IP address is 192.168.0.100 in static mode. On the back panel, a reset button
allows the user to return to this IP address by default.

Press the RST (reset) button and hold it for 2 seconds. The ETH LED will blink during this
process.

Connect the remote PC through a crossover Ethernet cable or through a network hub. Set the
PC IP address to an address belonging to the same sub-network (e.g. 192.168.0.001).

Press the RST button and hold it for 2 seconds. The ETH LED will blink during this process and,
after roughly 5 seconds, the SAS-E will restart. Wait two minutes.

On the PC, open a web browser page to

http://192.168.0.100/

. Click to enter the web interface.
Go to the "System Setup">"Network Setup" web page. Type in the password (the factory default
is "

pwd

"). Modify the mode of IP address allocation (static or DHCP) and static address as

necessary.

If the SAS-E is already DHCP configured and if no DHCP server is available, you cannot
connect a PC to access the SAS-E network configuration pages. You may use the reset button
on the back panel to reset the IP address in this case.

Configuring and Operating the SAS----EEEE

The SAS-E must be configured through an Ethernet network with a web browser.

After the boot sequence, open a browser to the SAS-E IP address (http://192.168.0.100). Go to
“SAS-E Configuration” > “SAS-E Setup” and program the setup parameters as follows.

For both channels, the fields (2 to 5) allow the user to set up the signal monitoring process.
Each input of the SAS-E (Frequency, 1 PPS, ToD, and Alarm) can be monitored individually
with the “Enable” or “Disable” selections. The channel is considered OK when all monitored
signals are connected and present.

The field (1) “Channel” allows the user to monitor the channel inputs. When this field is on “only
A” or “only B”, the SAS-E forces the selected channel, whatever the results of the over channel.
The switching function is disabled. The default of the channel (loss of one monitored signal)
generates an Urgent alarm. The SAS-E does not switch on the other channel. The front panel
switch is locked.

The programming of field 8, “Network channel selection”, and field 9, “front panel”

o

The front panel switch

In this configuration, the SAS-E has 3 modes:

o

“Forced A”: When this mode is selected, the LED “AUTO” in the front panel is always off

and the LED “A” is on. This mode forces the selected channel A, whatever the results of
the signal monitoring process.

In the case of a channel A default, the “Urgent Alarm” is active, and in the case of a channel B
default, the “Non Urgent Alarm” is active.

o

“Forced B”: When this mode is selected, the LED “AUTO” in the front panel is always off

and the LED “B” is on. This mode forces the selected channel B, whatever the results of
the signal monitoring process.

In the case of a channel B default, the “Urgent Alarm” is active, and in the case of a channel A
default, the “Non Urgent Alarm” is active.

o

“Automatic”: When this mode is selected, the LED “AUTO” in the front panel is always

on. The selection of the channel (A or B) depends on the results of the monitoring
process. The following table gives the source selection versus fault detection.

Those 3 modes can be selected with:

o

Field 8 “Network channel selection”, which allows the user to force the SAS-E mode

through the Ethernet port

o

Field 9, “Front panel switch” which allows the user to enable or disable the front panel

switch

o

The front panel switch, when it is enabled through the Ethernet port

EPSILON Switch & Amplifier System E Spectracom Corporation

User’s Manual 3-4

It is possible to enable or disable the front panel switch via the Ethernet port. When disable, the
front panel switch has no action on the selection mode and this one could be only changed via
the field “network channel selection” or via the embedded SNMP “network channel selection”
command.

When the front panel switch is enabled, the field “Network channel selection” has no action on
the selection mode.

When the front panel switch is enables, to set the SAS-E in the mode…

o

“Forced A”, press and hold the key A for more than 2 seconds

o

“Forced B”, press and hold the key B for more than 2 seconds

o

“Automatic”, press and hold the key “auto” for more than 2 seconds.

According to the available power sources, enable or disable the Power Alarms using the "AC
Presence“ and “DC Presence” fields. A default on a supervised power generates a “Non Urgent
Alarm”.

All parameters are saved in a flash EPROM and are reloaded on further reboot.

In the case of a reboot and when the panel switch is enabled while Channel A and B are
monitored, the selection mode is set in the automatic mode by default.
