Figure 4: 7750 SR-a8 Chassis Slot Identification
As shown in Figure 4 , the 7750 SR-a8 chassis has two forwarding complexes. Each
forwarding complex has a single IOM-a and up to four MDA-a cards with a forwarding
capacity of 100 Gb/s.
MDA-a and MDA-aXP cards occupy a half of a chassis slot. MDA-a slot 1/1 and 2/1 are XP-
capable, meaning that they support 100 Gb/s MDA-aXPs. These slots support up to
100 Gb/s full-duplex bandwidth.
The remaining six MDA-a slots support 25 Gb/s full-duplex bandwidth. MDA-a cards must
be ordered separately from the chassis. An impedance panel must be installed in any empty
MDA-a slot. See
MDA-a Cards for more information.
