Product Introduction
Alcatel-Lucent 11075L-128-REV-2, also identified by BAC3282EAA, is a CBX-500 OC3 ATM processor card. It provides 4-port OC3/STM1 processing with APS support and 128 MB RAM for legacy carrier switching systems.
This is the kind of board maintenance teams buy when a CBX-500 needs an exact replacement, not a near match. Check the full revision, slot compatibility, and site configuration before installation.
Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| Card not detected by chassis | Wrong revision, bad seating, or incompatible slot | ✅ High | Reseat the card and compare the label to the chassis support list | Verify exact part and revision first |
| OC3 ports remain down | Optics issue, cabling fault, or peer-side failure | ❌ Low | Check the fiber jumpers, optics, and remote end alarms | Do not replace the processor first |
| APS does not switch over | Configuration issue or protection pair mismatch | ✅ High | Review APS settings and test failover in maintenance window | Confirm protection settings before swap |
| Intermittent traffic loss | Marginal contacts, power instability, or load issue | ✅ Medium | Inspect connector seating and monitor input power under load | Reseat and verify power stability |
| System alarms on boot | Firmware mismatch or hardware failure | ✅ High | Read the alarm log and compare version records | Check software compatibility before replacement |
If you are stuck, contact technical support with photos, rack details, and any diagnostic logs.

Frequently Asked Questions
Q: What is this card used for?
A: It is an Alcatel-Lucent CBX-500 OC3 ATM processor card. In practical terms, it handles ATM traffic processing on a legacy carrier switch platform.
Q: Is BAC3282EAA the same as 11075L-128-REV-2?
A: In this listing context, BAC3282EAA is the associated HECI/CLEI identifier for the 11075L-128-REV-2 card. Always confirm both identifiers against the removed part and the chassis record.
Q: Can I use this as a direct replacement?
A: Yes, if the revision and platform match exactly. On older telecom hardware, the part may fit physically but still fail if the revision is wrong.
Q: Is it hot-swappable?
A: Do not assume that. Legacy ATM processor cards can be sensitive, and a live swap can bring down the shelf if the site procedure does not allow it.
Q: Will my configuration stay intact after replacement?
A: Usually the configuration lives in the system, not only on the card, but you should back it up anyway. I have seen teams lose time because they replaced the hardware before saving the active settings and alarm history.
Q: Is this refurbished?
A: It is generally sold as new surplus or OEM stock unless stated otherwise. That is why the price is often below factory-new inventory.
Q: What should I check before buying?
A: Confirm the exact part number, CLEI/HECI, chassis family, and revision. If the old card failed, save the logs and take label photos before removal.
