Installing an Additional TSC in a TSU

This section describes how to add an additional Telecom Signaling Card into a TSU. The new TSC must of the same type as the other TSCs in the TSU. It is possible to add a TSC to a TSU on a running platform without disturbing the traffic.




	WARNING! Be sure to power off the TSU when instructed to do so.




	CAUTION: The following procedure involves disconnecting the TSU from the SS7 network. The HP OpenCall SS7 platform will therefore lose network links. However, depending on the platform, it may be possible for the traffic that uses these links to be redirected via other links. Do this in consultation with the personnel responsible for operating the platform.

You should be logged onto the active host as ocadmin.

If the platform has more than one TSU, divert the traffic from the TSU that you are going to work on. To do this, refer to “Diverting Traffic”.
If you have a 1-host platform with only one TSU, stop HP OpenCall SS7 by running the ss7Stop -all command. As a result, all traffic will be stopped.
Take anti-static precautions by wearing the grounding wrist strap.
Power off the TSU.
Remove all cables from the rear panel of the TSU and disconnect the TSC cables at the network end.
Slide the TSU out on its rails until it blocks.
Remove the cover of the TSU, as described in “Removing the TSU Cover”.
Remove the card cage from the TSU, as described in “Removing the Card Cage”.
Insert the new TSC into a vacant slot. Refer to “Adding a Card to a TSU” for help with this.
Note that you may need to remove other TSCs in order to gain access to the relevant slot. If this is the case, do not forget to replace them!
Re-insert the card cage into the TSU, as described in “Replacing the Card Cage”.
Replace the cover of the TSU, as described in “Replacing the TSU Cover”.
Slide the TSU on its rails back into the cabinet.
Reconnect all cables to the rear panel of the TSU, but do NOT connect any TSC cables at the network end yet. If you are using the optional connection panel, you will need to make the TSC connections via this panel.
Label the new TSC cables, stating what they are (E1, T1, V.35) and where they connect to (e.g. TSC5).
Power on the TSU and wait until the TSU has booted (approximately 2 minutes).
Check the LEDs on the TSU and the TSCs. See “Checking LEDs” for information on the LEDs and their meaning.
Configure the hardware. To do this, refer to “TSC Configuration: Installing an Additional TSC in a TSU”. As part of this procedure, you will connect the TSC cables to the network and restore the diverted traffic (if necessary).
