Overview of the Cisco Nexus 7718 Switch Installation Features

The Cisco Nexus 7718 chassis has 18 slots for one or two supervisor modules and up to 16 I/O modules. The chassis also holds up to six fabric modules, up to 16 AC or DC 3-kW and 3.5-kW HVAC/HVDC power supplies, and three fan trays. To group the many networking cables for each I/O module on this chassis, you can install cable management frames on the chassis. You can install optional locking front doors and you can install an optional set of air filters on the front door and cable management frames. The following figure shows the standard hardware features seen from the front of the chassis.

Three fan trays — only 1 fan tray, N77-C7718-FAN, is shown in this figure to show fabric modules in back. There are 2 types of fan trays: 38 mm Gen 1 fan trays (N77-C7718-FAN) and 76 mm Gen 2 fan trays (N77-C7718-FAN-2). Use the Gen 2 fan trays for Network Equipment Building System (NEBS) compliance when the Cisco Nexus 7700 M3-Series 12-port 100-Gigabit Ethernet I/O module (N77-M312CQ-26L) or the Cisco Nexus 7700 F4-Series 30-port 100-Gigabit Ethernet I/O module (N77-F430CQ-36) is installed on the switch.
