Overview

Overview

The Cisco Nexus 93108TC-FX3P switch (N9K-C93108TC-FX3P) is a 1-rack unit (RU), ﬁxed-port switch

designed for spine-leaf-APIC deployment in data centers. PoE is supported on ports 1-48. This switch supports

the following ports:

• 48 100M/1/2.5/5/10GBASE-T ports (ports 1-48).

• 6 40/100-Gigabit ports QSFP28 (ports 49-54)

• Two management ports (one 10/100/1000BASE-T port and one SFP port)

• One console port (RS-232)

• 1 USB port

This switch includes the following user-replaceable components:

• Fan modules (four) with the following airﬂow choices:

• Port-side exhaust fan module with blue coloring (NXA-FAN-35CFM-PE)

• Port-side intake fan module with burgundy coloring (NXA-FAN-35CFM-PI)

This switch runs with +1 redundancy mode, so that if one fan fails, the switch

can sustain operation. But if a 2nd fan fails, this switch is not designed to sustain

operation. Hence before waiting for major threshold temperature to be hit, the

switch will power down due to Powered-down due to fan policy trigger.

Note

• Power supply modules (two—One for operations and one for redundancy [1+1]) with the following

choices:

• 1100-W port-side exhaust AC power supply with blue coloring (NXA-PAC-1100W-PE)

• 1100-W port-side intake AC power supply with burgundy coloring (NXA-PAC-1100W-PI)

• 1900-W port-side intake AC power supply with burgundy coloring (NXA-PAC-1900W-PI)

All fan modules and power supplies must use the same airﬂow direction.

Note

This switch may present access issues if installed between switches with greater

chassis depth. Please consider this before installation.

Depending on whether you plan to position the ports in a hot or cold aisle, you can order the fan and power

supply modules with port-side intake or port-side exhaust airﬂow. For port-side intake airﬂow, the fan and

power supplies have burgundy coloring. For port-side exhaust airﬂow, the fan and power supplies have blue

coloring.

The fan and power supply modules are ﬁeld replaceable. You can replace one fan module or one power supply

module during operations so long as the other modules are installed and operating. If you have only one power

supply installed, you can install the replacement power supply in the open slot before removing the original

power supply.

All fan and power supply modules must have the same direction of airﬂow. Otherwise, the switch can overheat

and shut down.

Note

If the switch has port-side intake airﬂow (burgundy coloring for fan modules), you must locate the ports in

the cold aisle. If the switch has port-side exhaust airﬂow (blue coloring for fan modules), you must locate the

ports in the hot aisle. If you locate the air intake in a hot aisle, the switch can overheat and shut down.
