2.Be administered via the add ds1 PCSS command, and
3.Be physically inserted into the correct slot.
A DS1 (UDS1-BD and DS1-BD) differs from most circuit packs in that
inserting the circuit pack into the switch is not enough to make the board
usable. It must also be administered with the add ds1 command.
d. No Aux Data: A wrong circuit pack is inserted in the slot where this circuit
pack is logically administered. To resolve this problem, either remove the
wrong circuit pack and insert the logically administered circuit pack OR
use the change circuit-pack command to readminister this slot to match
the circuit pack inserted.
Aux Data 3: The 24/32-channel option jumper setting on the circuit pack
does not match the option set on the DS1 circuit pack administration form.
The circuit pack must be physically removed to see the setting of the
jumper.
e. This error is associated with the Common Port Circuit Pack Maintenance
Test. Refer to XXX-BD (Common Port Circuit Pack) Maintenance
documentation for details.
f. The UDS1 Interface circuit pack has detected a transient hardware
problem. The value in the Aux Data field indicates the type of hardware
problem.
If the UDS1 board detects only one of these hardware problems, then the
error will disappear when none of these faults are detected for 10 minutes.
If the same Aux Data value is logged more than once in a 24 hour period,
the circuit pack should be replaced.
g. LAN External RAM Error. This error occurs when there is a hardware fault
in the PPE external RAM. The RAM is used for message buffering to and
from the Packet Bus. This error should not occur regularly. If this error is
seen quite frequently (10 times within 30 minutes), the circuit pack should
be replaced.
h. Transmit FIFO Underflow Error. This error occurs when the circuit pack
cannot find the "end of frame" bit when transmitting a frame to Packet Bus.
An alarm will be raised if this error occurs three times within 10 minutes.
Clear the alarm via the following commands: busyout board PCSS, reset
board PCSS, test board PCSS long, release board PCSS. If the error
recurs within 10 minutes, then replace the circuit pack.
i. Unable to Write LAN Translation RAM Error. This error occurs when a call
is aborted because there are no available translation RAM locations for
the call connection attempt. An alarm will be raised if this error occurs two
times within 10 minutes. Clear the alarm via the following commands:
4352 External RAM failure
4353 Internal RAM failure
4355 Internal ROM failure
