MISPs
•MISPs are inserted into the CE/Network Module for options 51C and 61C, and the Network Module for options 81C. Refer to the LD 22 printout to identify modules with unused network card slots and to Table 1 for the card slots in these modules that can house MISPs.
•An MISP cannot share network loop addresses with a Superloop Network Card in options 51C, 61C, and 81C. The MISP requires two network loop addresses and one network card slot.
•An MISP supports a maximum of eight BRSCs and two line cards.
•An MISP supports a set of four SILCs or UILCs when not supporting a BRSC.
•An MISP can support both BRSCs and SILCs or UILCs at the same time. If it serves one BRSC, a MISP can also support three line cards. If it supports two or more BRSCs, a MISP can also support two line cards.
BRSCs
•Install one BRSC per IPE module.
•With a BRSC configured, an IPE module can support a maximum of 15 line cards. These may be up to eight UILCs combined with any other seven peripheral cards (including SILCs), or up to 15 SILCs.
SILCs/UILCs
•SILCs, UILCs and BRSCs are installed into the IPE card slots of the CE/PE Module and/or the IPE Module for option 21E. They are installed into the IPE Module for all other system options. Refer to the LD 20 printout to identify modules with unused peripheral card slots.
