=== LED Indicators ===
====Base Model ====
The model ICE-CLKPPS-DST-000 has one Power LED indicator on the front of the chassis. This Power LED will illuminate green as soon as the chassis is plugged in.

====Models with Embedded Oscillator====
The model ICE-CLKPPS-DST-093 (and 010) have one Power LED indicator on the front of the chassis and an additional 10MHz reference lock LED on the front and back of the chassis.
<!--Old
The embedded low phase noise oscillator reference warm-up typically takes 30-50 seconds for the oven (OCXO) to achieve temperature and lock to an external 10 MHz reference.-->
<!--Edited-->
It typically takes 30-50 seconds for the embedded low-phase-noise reference oscillator to warm up, during which its oven (OCXO) achieves temperature, and it locks to an external 10 MHz reference.
Both lock LEDs on the front and back of the chassis will illuminate green when the reference is locked. The warm-up time may be longer depending on ambient temperature at the installed location of the unit.

==Optional Embedded Low Phase Noise Oscillator==
An embedded low phase noise oscillator is included with some models (see [[#Models|Models]]).
The oscillator can be customized for a specific fixed frequency. Please contact ICE for further details.

===Power Supply===
SynchronICE can be shipped with either an AC or DC power supply. The default configuration is an AC Supply. The power supply is cold swappable. The unit powers on immediately when the AC power cord is plugged into the chassis. This is the default configuration for infrastructure units that provide distribution of reference signals to down-stream devices.

==== AC Power Supply ====

=== Rack Mounting ===
* SynchronICE can either be front-mounted or reverse-mounted.  
* The rack slides are produced by General Devices and are Chassis Trak Telescoping Slides part number C‐300‐S‐124‐RC CC3041‐00‐240. 
* Any General Devices C‐300 series rack slides will work with any SyncronICE model.

====Forward Mounting====
The forward-mounting position is the default orientation when shipped:

{{Figure|sync-front-mount-holes_1033x135.png|Figure 10 ‐ Front Mounting Rack Slide Holes}}

====Reverse Mounting====
To change to reverse mount orientation follow the instructions below:

== Example Scenarios ==
=== Example Scenario of Channel 1 ===
Embedded LO distribution to 8 ICE-A2Dm14 Modules

{{Figure|sync-example-diagram_1057x475.png|Figure 12 ‐ Maximum Clock Accuracy Scenario}}

=== Example Scenario of Channel 2 ===
The standard chassis has one 10 MHz input and eight 10 MHz output channels.

=== Example Scenario of Channels 3, 4 ===
These are both TTL logic channels. 1 PPS and DC IRIGB002 are typical distribution logics.

It is also possible to use the output of the [[ICE-PIC|ICE-PIC Card]] center sync port as an input to one of these channels with the 8 outputs going to down stream ICE-PIC Card center ports (slaves to the card from which the input pulse originates). When using this scenario, the port is no longer used for DC IRIGB, and NNTP time must now be used to determine the second.

== Disclaimers ==
The ICE-CLKPPS-DST 1U distribution chassis is designed with the specific intent of synchronizing multiple ICE-PIC Cards. It can also provide distribution of TTL signaling and analog sources. Example scenarios are shown above. We recommend testing of this unit to validate your operational scenarios.

All specifications are subject to change without notice. Your application and use scenario for this unit may alter the performance metrics.

== Warnings and Cautions ==

SMA connections J01, J02 are D-Stamped. Do not over-torque. We recommend first to finger tighten with the blue tool provided.

{{Figure|Sma_hand_tool_400x224.png|Figure 13 – Included Hand tightening SMA wrench|400px}}
Then we recommended purchasing the SMA Torque Wrench (shown here) to tighten the SMA connectors the remainder of the way down.

74Z-0-0-79 Huber Suhner SMA Torque Wrench, .45Nm, 8mm/.315"

Part #: 419X416 Model #: 74Z-0-0-79

The Huber Suhner 74Z-0-0-79 steel SMA torque wrench is designed for use on SMA connectors. It has a torque of .45 Newton-meters (3.98 inch-pounds) and an opening of 8mm (.315"). Since the proper tightening torque ensures optimal performance over time, this break-over style torque wrench pivots when the torque setting is achieved, preventing over-torque conditions. Ergonomic styling makes the handling of this 4.5" long torque wrench easy.
