The alarms could potentially occur on any of these boards, as well: OC48AS, GigE, OC192 or
OC192LR. This issue will be resolved in a future release.

E1-14 boards with second source components can incur bit errors under extreme environmental
conditions. When these boards operate under voltage and temperature stress conditions and a
temperature ramp rate of 1 degree per minute, the boards could exhibit dribbling bit errors at high
temperatures: BER = 5.5e-6. To avoid this, you must apply the temperature ramp rate at 0.5 degree per
minute. This ramp rate complies with the NEBS standard; however, this issue will be revisited in a future
release.

Activating to Release 4.6.2 or 4.6.3 might result in a stuck Protection Not Available (PROTNA) alarm
on the cross connect card after activation completes. One of the cross connect cards would be in active
state and the other in standby state. Reset the Active TCC (Shelf Controller Card) to recover from this
issue. This issue will be resolved in a future release.

DDTS # CSCec42769 Database Corruption with ONS 15454 SDH Release 4.0, 4.0.1, 4.1
Caution
Before you upgrade to Release 4.6.3 from Release 4.0, 4.0.1, or 4.1, you must read this caveat and run
the SDH Circuit Repair Utility (VcCheck) provided on the software CD (also available on CCO).

The XCVXL card on the ONS 15454 SDH allows the intermixing of VC12 and VC3 payloads within a
single VC4. When a VC4 contains only one VC12 tributary and at least one VC3 tributary and the VC12
is deleted, the database becomes corrupt.

is deleted, the database becomes corrupt.
The database load process on the ONS 15454 SDH occurs during a TCC2 reboot, TCC2 protection
switch, software activation, or database restore. When the database is loaded containing this corruption
the load process fails, causing the corrupt database to be deleted from the TCC2 flash memory. The
previous saved database is then loaded instead. When all saved databases on a TCC2 contain the
corruption, the TCC2 will load with the default provisioning, and all existing provisioning will be lost.

the load process fails, causing the corrupt database to be deleted from the TCC2 flash memory. The
previous saved database is then loaded instead. When all saved databases on a TCC2 contain the
corruption, the TCC2 will load with the default provisioning, and all existing provisioning will be lost.
If this issue occurs you will see a loss of either some or all provisioning after a TCC2 switch or reset.
To ensure that your network is not vulnerable to this issue, you must first determine if the issue already
exists within your network, and if so, correct it. You can detect the issue by using the SDH Circuit
Repair Utility (VcCheck) provided on the ONS 15454 SDH Release 4.1.3 and 4.6.x software CDs. The
VcCheck tool is also available for download from CCO. Once you have alleviated immediate risk from
the issue, you must upgrade to Release 4.6.1, or maintenance Release 4.1.3 (or any later release) to avoid
further risk.
