Help installing a TN744E Call Class

Yeah. it's already got a few Call Class's in it. he new ones are for expansion. These boards aren't needed right now but I want to get them in now. They're going into various sites across EMEA, all of which are ESS. Fully duplicated on all.

Yeah, fully duplicated. All the site they're going in are ESS, one of them is currently the active pair of 87's. They're not needed right now but I want to get them in now in advance of future expansion. I'd like to be able to send a few basic steps to the engineers on each site (they're across EMEA). Also got the same question for TN71DP's ((main/test) too if you can help me with that! ;-)
ok dokey are you familiar with locking down the SPE's etc etc
or do you want me to send you the whole lot on how to lock down the active and power off standby replace boards in standby then interchange processor and repeat
will i send you the whole lot?
cheers

whats your email mate i will send you over all you need for future SPE circuit pack replacements
+ adding standard circuit packs
general rule is if they are SPE(white TAB) requires a spe lockdown procedure before swapping
if it has a purple TAB these are hot pluggable!!
anyway what's your E-Mail?

Below is the proceedures for a traditional switch. I am sure the S8??? would be different. I put this together for my tech's so that they could do it in the event I wasn't here and it needed to be done.
Replacing SPE circuit packs in a Duplicated system
Unlike a port carrier that is used for station circuit packs, you must power down one of the processors in a duplicated system before you can replace any circuit packs in that carrier. Always be sure to match the vintages on any circuit packs in A and B processors to insure their will be no conflicts in the software. Also before replacing any circuit packs to a higher vintage, make sure that our current version of software in the switch will support that pack. You can use the command “newterm” to display the current version of software. Below are the procedures for powering down a SPE.
1. Save translations
This step takes all translations on the 3 memory boards in both processors A&B and saves these translations to the hard drives in both processors.
Make sure that both processors show “Success” after this command completes.
2. Back up disk both full
This step saves all translations that have been saved to the hard drives and stores this information to the optical disk drives. Again this is done on A&B processors. The same is true for this command as with the save translations. Look to make sure that both SPE’s show “Success” after the command is complete.
3. Status SPE
This command will show the active and standby SPE locations. Make sure the SPE you need to shut down is in standby mode. If it is not, use the “Reset system I” command to change the SPE from active to standby. Use the status SPE command again to make sure the now active SPE is up and fully functional with no alarms present. Repeat this command until it is before proceeding.
4. Status Port Network
This command will allow you to see which tone clock is active and which is in the standby mode. You need to be sure that the active tone clock is in the active SPE that you are not taking down. If the tone clock is in the wrong SPE use the “Set tone clock” 01A or 01B to set it in the right SPE. The use the status port network command again to make sure it changed to the right SPE.
5. Power down procedures.
. Lock the SPE that you want “active” by using the toggle switches on the duplication interface pack. There are 3 positions on this. A, B, and auto select. One at a time, move the select switches on A and B SPE’s to the desired SPE setting on the duplication interface packs. This will lock the active SPE. You are now ready to power down the standby SPE. Remove the power cord to the left power supply first. Then remove the cord to the right power supply. Wait until there are no lights present on the power supplies. The offline processor is now down. At this time you can replace any pack in this carrier.
6. Power up procedures
After making sure that you have seated the circuit packs you have replaced correctly, you can now plug in the power cords to the power supplies. First plug in the power cord to the right power supply and then plug in the left power supply. Move the select switches on the duplication interface packs back to “Auto select”.
7.Alarm resolutions
The standby SPE should now be trying to come up. This may take 5 to 10 minutes. You can track this process using the status SPE command. This will show you the status of the hard drives, optical disk, processors and selector switches positions. It will also show you the status of the handshake, shadowing, and if the standby SPE is refreshed. After the standby SPE comes completely up is should show that
1. Handshake is up
2. Shadowing is on
3. Standby refreshed is yes
4. SPE selected is AUTO
5. State of health is functional
6. R-media and Disk are in-service
If the standby SPE does not come back up it may be necessary to do a “Busy out SPE standby” command. Then do a “release SPE standby” to make it functional again.
* To replace another circuit pack in the active SPE repeat steps 3 through 7.

Hi Mikey,
The work I need to do appears to be quite a bit different to your description. I've got dup'd PNC and the dual SPE environment is served by the S87's. I'm also putting them in duplicated G650's with 2 in each PN so I can't shut down the PN's whilst doing this. I've not got any hybrid MCC's in the config and have no R-Media/Hosta adapters either.
Thanks for your efforts but I'm still in need of further info.
Cheers,
Si
