ImageStream - Hardware Upgrade


This document gives you basic unpacking, configuration and installation information for hardware upgrades to your ImageStream router. Only authorized service personnel should perform these procedures. Follow all standard safety and ESD precautions when servicing the server. See "Static Electricity Precautions" below for more information on ESD precautions.

Static Electricity Precautions

Take care when handling any eletronic components. The active components are sensitive to electrostatic discharge (ESD), and can easily be damaged. ImageStream recommends that you use an antistatic wrist strap when handling SBCs, WAN cards, processors, memory and any associated components. Also, follow these rules:

  1. Wear a grounding wrist strap (available at most electronic stores).
  2. Turn off the system power.
  3. Touch the back of the power supply fan, located on the back of the case.
  4. Unplug all cords from electrical outlets.
  5. Remove the system cover only after completing the above steps.
  6. Avoid static-causing surfaces such as plastic and styrofoam in your work area.
  7. Remove the parts from their antistatic bags only when you are ready to use them. Do not place parts on the outside of static bags, since only the inside provides antistatic protection.
  8. Always hold cards by their edges and their metal mounting bracket. Always hold processors and memory by their edges only. Avoid touching components on the cards and the edge connectors that connect to the expansion slots.
  9. Never slide cards or other parts over any surface.

Unpacking Your Hardware

If the shipping carton is damaged when you receive it, request that the carrier's agent be present during the unpacking and inspection of the equipment. Unpack the equipment from the shipping carton. Refer to the packing list and verify that all items are present. Save the packing material for storing and reshipping of equipment.

Observe all ESD precautions. Avoid touching areas of integrated circuitry. Static discharge can damage circuits.

Before Installing the Hardware

After removing the hardware from its packaging:

  • Check for obvious physical damage.
  • For single-board computers, verify that the coin cell battery is in its holder, and that the system memory, processor(s) and flash device and inserted correctly.

Make sure that you disconnect the chassis from the main power supply before you continue.

Installing the Hardware

PCI expansion cards, PCI SBCs

ImageStream WAN cards and SBCs fit into standard 64-bit or 32-bit standard PICMG connectors on the backplane or mainboard of your router. The card secures to the system enclosure by one slot cover. Your backplane or mainboard may have several slots for the installation of expansion cards. Expansion cards can be extremely sensitive to ESD and require careful handling. After removing the card from its protective wrapper or from the system board, place it component-side up on a grounded, static-free surface or conductive foam pad. Do not slide the card over any surface.

  1. Remove the screw from the board retaining bar, if your router is equipped with one.
  2. Remove the board retaining bar.
  3. Remove the expansion card from its protective wrapper. Be careful not to touch the components or the gold-edge connectors.
  4. If adding a card, remove and save the expansion slot cover.
  5. If replacing a card, remove the mounting screw and firmly and evenly pull the card to be replaced directly up and out of the chassis.
  6. If installing a single board computer (SBC), locate the system. The SBC will only install in this slot. Contact ImageStream Technical Support if you have difficulty locating the system slot.
  7. Hold the expansion card by its top edge or upper corners. Firmly press it into the expansion slot on the backplane or mainboard. The tapered foot of the board retaining bracket must fit into the empty slot in the chassis frame.
  8. Insert the mounting screw you removed from the slot cover and tighten to hold the card in place.
  9. Replace the board retaining bar, if your router is equipped with one.
  10. Replace the screw in the retaining bar.
  11. Cover the slots to properly cool the system and to minimize the risk of electric shock.
  12. Replace the chassis cover.

Startup Verification

You can power up the system after you verify that:

  • all necessary hardware preparation is done
  • all connections are correctly made
  • the installation is complete

Replacing the On-board Lithium Battery

Do not service or replace the lithium battery in the field. Contact ImageStream Technical Support to arrange for service or battery replacement.

If you must replace the lithium battery use the following guidelines:

  • When replacing the battery, you must apply power to the board to prevent data loss.
  • Dangerous voltages, capable of causing death, are present in this equipment. Use extreme caution when handling, testing and adjusting.
  • Lithium batteries incorporate flammable materials such as lithium and organic solvents. If lithium batteries are mistreated or handled incorrectly, they may burst open and ignite. This can result in injury and/or fire. When dealing with lithium batteries, carefully follow the precautions listed below to prevent accidents.
  • Do not short-circuit.
  • Do not disassemble, deform or apply excessive pressure.
  • Do not heat or incinerate.
  • Do not apply solder directly.
  • Do not use different models, or new and old batteries together.
  • Do not charge.
  • Always check proper polarity.

    To replace the on-board backup battery, follow the steps below.
    1. There is danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type recommended by the equipment manufacturer. Dispose of used batteries according to the manufacturer's instructions.
    2. Attach an ESD strap to your wrist. Attach the other end of the ESD strap to the chassis as a ground. Secure the ESD strap to you wrist and to ground throughout the procedure.
    3. To remove the battery from the module, carefully pull the battery from the socket.
    4. Before installing a new battery, make sure the battery pins are clean.
    5. Note the battery polarity and press the new battery into the socket.
    6. Avoid touching areas of integrated circuitry. Static discharge can damage circuits.
    7. No soldering is required when the battery is in the socket.
