[kewitz]

hello can anybody tell me the differences between ESH and ESH2 modules. perhabs you can give me a ref for a download thx kewitz

ESH FC modules support 1GB speeds and have a manual terminate FCAL switch.
ESH2 FC modules support 2GB speeds and are FCAL autoterminating.

"ESH2 is the enhanced version of ESH modules. The ESH2 offers several improvements over the ESH including a next-generation ASIC chip, improved design and bug fixes, broadly available components for faster supply responsiveness, and a modular board design that allows one to flexibly switch between optical and copper.

ESH2 has the following different features which are not in ESH:

- ESH2 uses an optical SFP module to make it "optical".
- ONTAP: ESH2 requires ONTAP 6.4.4 or 6.5.1 and above. Note that ONTAP 6.5.0 is NOT supported.
- Compatibility Within Shelf: ESH2 is incompatible with ESH within the same shelf. A single shelf must either have 2 ESH modules or 2 ESH2 modules. Placing an ESH2 shelf and ESH shelf within the same loop is perfectly fine.
- Termination Switch: ESH2 is self-terminating and does not have a terminate switch.
- Platform Compatibility: ESH2 is fully compatible with FAS270; ESH is absolutely NOT compatible
