Release Notes for Cisco ONS 15454 SDH Release 4.6.6
OL-4855-01
Caveats
CSCdw14501 
Interconnection Equipment failure alarms may be generated at 55 degrees C, and 72 volts. When the 
operating environment is at 55 degrees C and 72 volts, interconnection equipment failure alarms for the 
following cards can occur: 
STM16SH
STM64LH
STM16LH
XC10G
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.
Upgrades
CSCee36132, CSCee66259
Activating to Release 4.6.2, 4.6.3, or 4.6.6 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 is resolved in Release 5.0.
CSCec42769 Database Corruption with ONS 15454 SDH Release 4.0, 4.0.1, 4.1
Caution
Before you upgrade to Release 4.6.6 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. 
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. 
If this issue occurs you will see a loss of either some or all provisioning after a TCC2 switch or reset.
