This section describes how to replace an add-on LAN card (HP
Part Number: D5013-60002), located in slot L1 in the TSU, which
is used in a 2-host platform. It is possible to add a LAN card in
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. | | | | |
| | | |  | NOTE: Slot L0 in the TSU is occupied by the system CPU card,
which also provides a host LAN connection. This card is supplied
with the TSU and cannot be removed. If there is a problem with this
card, call your HP representative. | | | | |
You should be logged in as ocadmin on the
active host. 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. 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”. Remove the old LAN card from
slot L1 and install the new card in its place. Refer to “Removing
a Card from a TSU” and “Adding
a Card to a TSU” for help with this procedure. Note that if there is a TSC installed in slot 5, you
will need to remove it before you can gain access to slot L1. Do
not forget to replace it! 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. Power on the TSU and wait until
the TSU has booted (approximately 2 minutes). Use the command ss7TsuPing -v to see the new MAC address of the replacement LAN card. Run the hardware replacement
command ss7HwReplace. If the tool returns an error, refer to the HP OpenCall SS7 Troubleshooting
Guide. When asked if you wish to load the updated configuration,
answer affirmatively. Do not accept changes now - move to another window to continue
or quit the tool - if you accept the changes, no rollback will be
available. If you have diverted the traffic
from this TSU, you can now restore the traffic to the TSU. To do
this, refer to “Restoring
the Traffic”. If you have stopped HP OpenCall SS7, you can now restart
it. To do this, run the ss7Start command. Configure the hardware. To do
this, refer to “LAN Configuration:
Replacing a LAN Card in a TSU”.
RollbackYou should be logged in as ocadmin on the
active host. You should only perform this rollback when instructed to do
so in the procedure “LAN Configuration:
Replacing a LAN Card in a TSU”. 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. 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”. Remove the replacement LAN card
from slot L1 and re-install the former card in its place. Refer
to “Removing
a Card from a TSU” and “Adding
a Card to a TSU” for help with this
procedure. Note that if there is a TSC installed in slot 5, you
will need to remove it before you can gain access to slot L1. Do
not forget to replace it! 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 the power and LAN cables
in the rear panel of the TSU but do NOT connect the TSC cables (that
connect to the signaling network) yet. Power on the TSU and wait until
the TSU has booted (approximately 2 minutes). Rollback the configuration changes
by carrying out either of the following: run
the command ss7HwRollback reject the updated configuration
in the ss7HwReplace window.
Reconnect the TSC cables to the
rear panel of the TSU in order to reconnect to the signaling network. If you have diverted the traffic
from this TSU, you can now restore the traffic to the TSU. To do
this, refer to “Restoring
the Traffic”. If you have stopped HP OpenCall SS7 on the hosts, you can
now restart it. To do this, run the ss7Start command.
