Figure 1: NC57-18DD-SE Line Card
Port 0 to 17 and Port 24 to 29 can only be used in pairs (one top port and its respective bottom port make a
pair), with the following restrictions:
• If the top port has 400GE optic, then the bottom ports cannot be used.
• If the top port has 200GE, 100GE, or 40GE optic, the respective bottom port in the pair should also be
200GE, 100GE, or 40GE optic.
Modular Port Adapters
The modular port adapters (MPAs) are supported in the NC55-MOD-A-S and NC55-MOD-A-SE-S line card.
Each MPA has a STATUS and ATTN (attention) LED, and each port on the MPA has an adjacent A/L
(Active/Link) LED.
To determine which transceivers and cables are supported by these MPAs, see Cisco Transceiver Modules
Compatibility Information.
Note
4-Port 40GE/100GE MPA with QSFP+/QSFP28
The 4-port 40GE/100GE MPA (NC55-MPA-4H-S/NC55-MPA-4H-HD-S/NC55-MPA-4H-HX-S) provides
4 ports for 4x25GE (via cable breakout), QSFP+ (40Gbps) or QSFP28 (100Gbps) transceivers.
The temperature-hardened NC55-MPA-4H-HD-S MPA operates within industrial temperature range when
installed in the temperature-hardened routers.
Note
The temperature-hardened conformal-coated NC55-MPA-4H-HX-S MPA operates within industrial temperature
range when installed in the temperature-hardened routers.
