03345-02_RTM_Installation_Guide

Prepare for installationBefore you install the RTM:•Verify it is compatible with its corresponding frontmodule. Refer to the documentation for the RTM.•Make sure you are adequately grounded beforehandling the RTM, as described in the previoussection, Before you begin.•The RTM may be mechanically keyed to prevent itsaccidental insertion into an incompatible frontmodule. Be careful to note any special keyingbefore inserting the RTM.•Determine which front node slot in the shelf youplan to use for the front module. The RTM will beinstalled in the corresponding rear slot. Forexample, if you intend to install the module in frontphysical slot number 3, install the RTM in rearphysical slot number 3.•Remove the airflow management panel, if present,from the back of the shelf where the RTM is to beinstalled.•Install any components not included with the RTM,such as a hard disk drive and SFP transceivers.

The RTM provides additional I/O connections to the front module through the back side of the shelf.The RTM attaches to the shelf using standard Zone 3 connectors, as shown in Figure 2 on page 4. These connectors receive power from the shelf for the RTM’s rear panel I/O circuitry and also provide signaling and management connections.Before you beginTo ensure all safety precautions are followed during installation and setup, review the Safety Information document on the downloads page for the RTM at /downloads.Obey ESD proceduresW ARNING! Obey the electrostatic discharge (ESD) procedures described at /esd when you install the product. Electrostatic discharge can cause permanent damage to static‐sensitive components in this product.Important ESD procedures include:•Keep the product in its ESD shielding bag until a step tells you to remove it.•Put on a grounded wrist strap before you move near or touch the product.•Install the product only in a grounded work area.Install SFPsSome RTMs have sockets that accept SFP (small form‐factor pluggable) transceiver modules,which provide external connections to Ethernet interfaces. The sockets are typically located onthe face plate of the RTM. Standard RTM configurations are shipped with SFP filler plugs installedto protect the internal components of the RTM.For a list of tested and qualified transceivers, see the Component Compatibility Report in theAdvancedTCA downloads section of the RadiSys Web site at /downloads.Transceiver installation Figure 1. Transceiver insertionFigure 1 shows the correct orientation for inserting Array an SFP transceiver. The transceiver may vary inappearance, but the same insertion guidelinesshould be used.1.Obey the ESD procedures in Before you beginon page 1, making sure you are adequatelygrounded.2.Remove the RTM and the transceivers fromtheir antistatic bags.3.On the RTM face plate, remove the filler plugsfrom the sockets where the transceivers will beinstalled. For sockets not being used, keep thefiller plugs in place.4.Make sure the latch on the cable end of thetransceiver is closed. This makes the SFP snapinto position when it is inserted into the socket.5.Hold the transceiver near the cable end andturn the connector side to the correct positiondepending on the RTM orientation:•If the RTM is vertical, turn the transceiver sothe connector side is on the right.•If the RTM is horizontal, turn the transceiver so the connector side is down.6.Insert the connector end of the transceiver into the socket.7.Once inserted into the socket, carefully slide the transceiver until its connector is fully seatedand the SFP snaps into position.8.Repeat the previous steps for each transceiver being installed.9.For transceivers with cable plugs installed on their cable end, keep the plugs in place until it istime to connect cables to the transceivers. The cable plugs protect the internal componentsof the transceivers from dust and foreign contaminants.Note: If an SFP needs to be removed, open the latch and pull the SFP out of the socket.Filler plug installationIf the SFP transceivers are removed, install either replacement transceivers or filler plugs toprotect the sockets, to control airflow, and to prevent electromagnetic interference.Install a hard disk driveSome RTMs can accommodate an optional hard disk drive (HDD) for additional data storagecapability. A separate HDD can be ordered from Radisys and installed onto the RTM prior toinstalling the RTM in the shelf. See the Component Compatibility Report for suitable hard diskdrives.Install the rear transition moduleThe RTM can be installed at any time, but it is easier to do so before the corresponding frontmodule is installed in the shelf. This section describes how to install the RTM before installing thefront module.1.To install the RTM in a new shelf, skip this step and continue with Step2.To add the RTM to an existing shelf, update each item in the order shown before proceedingwith the RTM installation. All updates and instructions are available from the RadiSys Website.a.Update the shelf FRU data with the FRU image file.b.Update the software on the corresponding front module to the latest version.c.Update the firmware on the corresponding front module to the latest version.2.Follow ESD precautions and make sure you are adequately grounded before handling theRTM.3.Remove the RTM from its ESD shielding bag.Figure 2. Generic RTM 4.Inspect the EMC gasket to make sure it Array is free of debris.5.Open both ejector latches on the RTM.6.Slide the RTM into the empty rear sloton the shelf. Use firm pressure to fullyseat the RTM in the backplaneconnector. Make sure the EMC gasketseals the surfaces it touches.7.Once the RTM is fully seated, carefullyclose both ejector latches at the sametime.Note: The RTM receives its power fromthe front module. If there is a powerLED on the RTM, it will not illuminateuntil the front module is installed.8.Tighten the retaining screws at the topand bottom of the RTM panel.9.Install the front module.e the shelf management software toverify the RTM and the correspondingfront module are available as resourcesand are operating correctly.Removing the rear transition moduleFigure 3. Opening ejector latches.Note: Some RTMs have two locking ejector Array latches, and others have one locking ejectorlatch and one friction latch. It is important thatthe lock is released before opening a lockingejector latch. See Figure 3 for an illustration ofthe ejector latches.To remove an RTM from the shelf:1.Release the two retaining screws.2.If one of the latches is a friction type,carefully pull the latch handle away fromthe RTM to open the latch. To open alocking ejector latch, disengage the lock bysliding the lock toward the handle torelease the catch from the shelf latch rail,then pull the handle away from the RTM.See Figure 3.3.Remove the RTM from the shelf.Where to go from hereRefer to the RTM documentation for information on how to operate and maintain the RTM, andfor detailed information on the RTM’s electrical, mechanical, and environmental aspects. In someinstances, RTM information may be found in the corresponding front module documentation.
