CHAPTER 1

Overview

•Overview, on page 1

Overview

The Cisco Nexus 93600CD-GX switch (N9K-C93600CD-GX) is a 1-rack unit (RU), fixed-port switch designed

for spine-leaf-APIC deployment in data centers.

This switch has the following ports:

• 28 10/40/100-Gigabit QSFP28 ports (ports 1-28)

• 8 10/40/100/400-Gigabit QSFP-DD ports (ports 29-36)

• Two management ports (one 10/100/1000BASE-T port and one 1-Gbps SFP port)

• One console port (RS-232)

• 1 USB port

This switch offers QSA 10G support on all ports.

Note

There is no support for 1-Gigabit nor 100-Megabit optics on this switch.

Note

For breakout information, see the Cisco APIC Layer 2 Networking Configuration Guide.

Leaf/Spine role considerations:

• This switch's default role is as a leaf switch.

• The default fabric links (ports 29-36) must be used for initial switch discovery via another switch.

• To change the switch from the default role, the switch must be rebooted (you must select the role of leaf

or spine, except in the case of the default spine switch being connected directly to the APIC).

• A default spine switch that is connected directly to the APIC will be converted to a leaf switch,

automatically.

Cisco Nexus 93600CD-GX ACI-Mode Switch Hardware Installation Guide

• Port-profile (downlink/fabric link conversion) can be done after it’s registered to the APIC.

Discovery considerations:

• Discovery via APIC – use the default downlink ports.

• Spine discovery – use the default fabric links (ports 29-36) and convert the switch to spine (reboot is

required).

• Leaf discovery via spine – use the default fabric links (ports 29-36).

• Sub leaf discovery via leaf – use the default fabric links (ports 29-36).

• Multipod (Pod 2+) first spine discovery via IPN – Connect the IPN to one of the default fabric links

(ports 29-36). Ensure the spine has at least one leaf node connected to it.

This switch includes the following user-replaceable components:

• Fan modules (six) 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

Each fan module has two rotors. The switch can function normally if one rotor

inside the any one fan module fails. In case of more than one rotor failure, the

switch will issue a warning and power down in 2 minute.

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-PE2)

• 1100-W port-side intake AC power supply with burgundy coloring (NXA-PAC-1100W-PI2)

• 1100-W port-side exhaust HVAC/HVDC power supply with blue coloring (NXA-PHV-1100W-PE)

• 1100-W port-side intake HVAC/HVDC power supply with burgundy coloring

(NXA-PHV-1100W-PI)

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

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