Cisco Cisco ONS 15454 SDH Multiservice Provisioning Platform (MSPP) 릴리즈 노트

Operating temperature of the DWDM GBICs is -5 degrees C to 40 degrees C.

SDH DS3-i and E3 electrical cards only support a VC4 J1 trace string setting for all VC4s together. You 
cannot set the J1 byte for individual VC4s. This issue is a limitation of hardware.    

VC3 J1 strings can be set individually, but the optical cards cannot monitor the VC3 J1 string.

Very rarely, an Equipment Failure Alarm can occur on an externally timed TCC+ or TCC-I card after a 
reset. If this occurs, BITS will be displayed as good for one TCC, but bad for the other. If the issue occurs 
on the standby TCC, a second reset could clear the problem. If the issue occurs on the active TCC, the 
card must be replaced. This issue is closed, as it does not occur with TCC2, and is otherwise very rare.

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.
