You can now enter SPE-down interface commands as described in
‘‘Using the
SPE-Down Interface’’. If the prompt does not appear, check the connections
between the terminal and the control carrier. Make sure the cable is connected to
the connector labeled
ACTIVE
. If possible, try a different cable and/or terminal. If
the prompt is still not present, replace the SYSAM circuit pack. If the SPE remains
down with no prompt, follow normal escalation procedures.
To return the standby SPE to service, see the following section on
‘‘Bringing the
SPE Back into Service’’.
SPE Locked Standby or Standby SPE-Down
To bring up the SPE-down interface on a functioning duplicated system, connect
the terminal to the STANDBY terminal connector on the rear panel of either
processor carrier. Assuming all cabling is intact, either connector will access the
SPE which is standby. If the standby SPE is down, the message and prompt
shown above are displayed. To enter SPE-locked-standby mode, carefully, and
one at a time
, move the SPE-Select switches to the position indicating the carrier
of the currently active SPE. For example, if the SPE in carrier A is active, move the
switches to position A. When the SPE is locked, SPE interchanges are prevented,
memory shadowing is turned off, handshake is down, and maintenance activities
normally controlled by software on the active SPE cease. The following message
is printed, (in this example, A is locked standby):
One of the following prompts will appear, indicating which SPE is locked
standby
and whether the SPE is down.
SPE_A_LOCKED>
SPE_B_LOCKED>
SPE_A_DOWN_LOCKED>
SPE_B_DOWN_LOCKED>
You can now enter the commands described in
‘‘Using the SPE-Down Interface’’
.
If the prompt fails to appear, check your connections. Try connecting to the
connector labeled STANDBY on the other PPN control carrier (A or B). If possible,
try using a different cable and/or terminal. If the above actions do not produce a
prompt, replace the SYSAM circuit pack on the standby SPE. If the prompt is still
not present, follow normal escalation procedures.
If an SPE was down and the SPE-Select switches are set to lock, the
down-and-locked-standby mode
replaces
the SPE-down mode. Normally, when
the standby SPE is up and cycling, the yellow LED on the Processor circuit pack
flashes on and off. If the SPE is locked standby
and
a terminal is connected to
the STANDBY connector, the Processor LED remains unlit.
