Option 11C and Option 11C Mini mix-and-match expansion
In a mix-and-match scenario, an Option 11C Mini Main chassis can be
connected to the Option 11C IP Expansion cabinet(s). In addition, an Option
11C Main cabinet can be connected to an Option 11C Mini IP Expansion
chassis. The main differences between the Option 11C and Option 11C Mini
include:
• The SSC card vintages - the SSC card NTDK20 or later is required for
the Option 11C Main Cabinet, Option 11C Mini Main Chassis and IP
Expansion Chassis. The SSC card vintage NTDK20CA or later is
required for Option 11C Expansion Cabinets.
• The Option 11C cabinets must support the faceplate cabling that is used
on all IP Expansion daughterboards. If the current cabinets do not
support cable routing through the faceplate, they must be upgraded to the
NTDK18AA cabinet kit.
• The grounding clips are situated differently. The Option 11C grounding
clip is mounted on the front of the stiffener rail. Refer to Figure 37 on
page 111. The Option 11C Mini is mounted on the fan baffle on the lower
right hand side of the Mini Main chassis Refer to Figure 38 on page 112.
