• M2 Series I/O modules
• 24-port 10-Gigabit Ethernet I/O modules with XL option and FEX support (N7K-M224XP-23L)
• 6-port 40-Gigabit Ethernet I/O modules with XL option (N7K-M206XP-23L)
• 2-port 100-Gigabit Ethernet I/O modules with XL option (N7K-M202XP-23L)
• M3 Series I/O modules
• 48-port 1-/10-Gigabit Ethernet SFP+ (N7K-M348XP-25L)
• 24-port 40-Gigabit Ethernet QSFP+ (N7K-M324FQ-25L)
• Network Analysis Modules (NAMs) (N7K-SM-NAM-K9
M3-Series I/O modules are not compatible with Sup-1 and Fab-1 modules. M3-Series I/O modules cannot be
combined with M1-,F1- or F2-Series I/O modules in the same Cisco Nexus 7018 switch.
Note
Starting with Cisco NX-OS Release 7.3(0)D1(1), the following I/O modules are not supported:
Note
• 32-port 1- and 10-Gigabit Ethernet I/O modules (N7K-F132XP-15)•
• 48-port 10/100/1000 I/O modules (N7K-M148GT-11)
• 32-port 10-Gigabit Ethernet I/O modules with FEX support (N7K-M132XP-12)
• 48-port 1-Gigabit Ethernet I/O modules (N7K-M148GS-11)
• Starting with Cisco NX-OS Release 8.0(1), the following I/O modules are not supported:
• 48-port 1-/10-Gigabit SFP+ (N7K-F248XP-25)
• 48-port 10/100/1000 with XL option (N7K-M148GT-11L)
• 48-port 1-Gigabit Ethernet with XL option (N7K-M148GS-11L)
• 32-port 10-Gigabit Ethernet with XL option and FEX support (N7K-M132XP-12L)
• 8-port 10-Gigabit Ethernet with XL option (N7K-M108X2-12L)
You can insert a maximum of ten 24-port 40-Gigabit Ethernet QSFP+ (N7K-M324FQ-25L) I/O modules in
the Cisco Nexus 7018 switch. This I/O module uses 96 VQI per slot. The maximum VQI of a Cisco Nexus
7018 switch is 1024 and a total of eleven 24-port 40-Gigabit Ethernet QSFP+ I/0 modules will require 1056
VQI. In such a scenario, the eleventh I/O module will attempt to come online 3 times and then will get powered
down. During a reload of a switch with eleven 24-port 40-Gigabit Ethernet QSFP+ I/0 modules, the I/O module
that comes up last will be powered down.
You must install the Cisco Nexus 7018 chassis in a four-post 19-inch EIA rack that meets the following
specifications:
• Mounting rails that conform to the English universal hole spacing as specified in ANSI/EIA-310-D-1992.
• The minimum vertical rack space is 43.75 inches (111.1 cm) or 25 rack units (RU) for a single chassis
installation and 87.5 inches (222.2 cm).
Install the Cisco Nexus 7018 chassis at the lowest possible RU on the rack for stability, as shown in Figure
12: Cisco Nexus 7018 Chassis Installed in a Four-Post Rack, on page 22. If there is another device in the
rack, install the heaviest one at the bottom.
