3 Maintain the ATCA Subrack
The shelf management controller in the shelf where the JAXSSW is to be
installed, treats the JBXSSW and the JAXSSW as one single unit. For this
reason it is not possible to install the JAXSSW while the JBXSSW is powered
up. Instead the JAXSSW must be installed while the JBXSSW is powered down
and then both the JBXSSW and the JAXSSW have to be powered up together.
3.6.2.1 Remove JAXSSW
To remove a JAXSSW:
1. Identify the board to be replaced. Refer to Board/Area/Slot/SBL Mapping
(Section 1.3) for details.
2. Perform the tasks listed in Remove JBXSSW (Section 3.5.5.1) for the related
JBXSSW board, but do not unplug the corresponding JBXSSW front plate.
3. Verify the cable labels and note the position for each cable.
4. Remove interface cables from front plate connectors.
5. Loosen two front plate screws.
6. Open handles of the JAXSSW.
7. Remove JAXSSW from rails of slot.
3.6.2.2 Insert JAXSSW
To insert a JAXSSW:
1. Locate the slot the JAXSSW is to be installed into the shelf’s rear which
must be the same as that of the front blade.
2. From BSC terminal or OMC-R, disable the corresponding
SSW_HW(JBXSSW) of the front blade in order to power down its payload.
The blue LED on the front blade starts to flash. This indicates that the
JBXSSW is informing the shelf manager about its desire to power down its
payload.
3. Wait until the blue LED on the front blade is ON.
This indicates that the JBXSSW payload is powered down.
4. Ensure that the top and the bottom handles of the JAXSSW are in outward
position.
5. Insert the JAXSSW into the shelf by placing the top and bottom edges in the
card guides of the slot. When plugging the JAXSSW in or removing it, do
not press on the face plate but use the handles.
6. Slide the JAXSSW into the slot
7. Hook the lower and the upper handle into the shelf rail recesses.
8. Fully insert the RTM and lock it to the shelf by pressing the two components
of the lower and the upper handles together and turning the handles
towards the face plate.
The JAXSSW’s blue hot swap LED is switched ON. This indicates that the
JAXSSW’s MMC is powered up.
9. From BSC terminal or OMC-R initialize/unlock the corresponding SSW_HW
(JBXSSW);
The blue LEDs of both the JBXSSW and the JAXSSW start to flash. This
indicates that the front blade is informing the shelf manager about its desire
to power up the payload of both the front blade and the JAXSSW.
