Previously, this catalog number position indicated which network management options are included. Effective 10/08,
these are now all part of our standard offering, which is equivalent to previous option H. Features can be disabled by
the user via software and are fully compatible with existing FOCUS not equipped with these features. Current selection
“A” is how previous chassis were configured as standard. Selecting any option “A, B, C, D or E” will automatically
include SNMP trapping, APM and remote configuration. One FCA module must be installed in one FOCUS node per
isolated network to make full use of the SNMP capability.

CE certified chassis depth is extended approx. 2” to include full rear cover over all terminals. The chassis has been
tested to EMI & RFI levels consistent with CE requirements. It is 4 RU high instead of our standard 3 RU and includes
adjustable mounting ears for front, or 8cm (3.25”) back from front rack mounting.
