Small update.
The L1400 is not just two L700e's bolted together, it's a different sales model, an enhanced version of the L700e. An L1400 only has the one frame if you need < 700 slots, but will still be called an L1400. The differences are:
1. MPCL replaces the MPC
2. L series web admin is standard
3. Library FC interface is standard
4. 700 slots installed, capacity controlled by s/w key
5. Standard 200 slots, inceased in 100 slot increments
6. Capacity key held in SN3300 router in 19" bay area
7. Library logical partitioning supported
Hope that helped.
