The GE Ethernet/IONet switches are available in two hardware forms:

ESWA and ESWB. Each hardware form is available in five versions 

(H1A through H5A) that vary in fiber-optic port configuration options,

which include no fiber ports, multi-mode fiber ports, or single-mode

(longer distance) fiber ports. Refer to the IS420ESWAH#A IONet Switch

Specifications table and the IS420ESWBH#A IONet Switch Specifications

table for these fiber option details.

The ESWx switches can be DIN-rail mounted using one of three GE qualified

DIN-rail mounting clips, depending on the hardware form (ESWA or ESWB)

and the selected DIN-rail mounting orientation. The clips are ordered separately,

in accordance with the following table. Mounting screws are included with each

switch.
