Cisco 9396TX - Manual

C H A P T E R 1 Overview • Overview, page 1 Overview The Cisco Nexus 9396TX switch (N9K-C9396TX) is a 2-RU, fixed-port switch designed for Top-of-Rack(ToR), Middle-of-Rack (MoR), and End-of-Rack (EoR) deployment in data centers. This switch has 48 fixed1- and 10-GBASE-T downlink ports and up to 12 f...

Altitude Requirements If you operate a switch at a high altitude (low pressure), the efficiency of forced and convection cooling isreduced and can result in electrical problems that are related to arcing and corona effects. This condition canalso cause sealed components with internal pressure, such ...

To predict and prevent strong EMI, you might need to consult experts in radio frequency interference(RFI). Note The wiring is unlikely to emit radio interference if you use twisted-pair cable with a good distribution ofgrounding conductors. If you exceed the recommended distances, use a high-quality...

• Two 930-W DC power supplies • One 650-W AC power supply and one 930-W DC power supply For power-supply redundancy, you must provide power to both power supplies. For grid redundancy, youmust provide power to both power supplies and each power supply must be connected to a different powersource. No...

Rack and Cabinet Requirements You can install the following types of racks or cabinets for your switch: • Standard perforated cabinets • Solid-walled cabinets with a roof fan tray (bottom to top cooling) • Standard open four-post Telco racks • Standard open two-post Telco racks To correctly install ...

Clearance Requirements You must provide the chassis with adequate clearance between the chassis and any other rack, device, orstructure so that you can properly install the chassis, route cables, provide airflow, and maintain the switch.For the clearances required for an installation of this chassis...

Unpacking and Inspecting a New Switch Before you install a new chassis, you need to unpack and inspect it to be sure that you have all the items thatyou ordered and verify that the switch was not damaged during shipment. If anything is damaged or missing,contact your customer representative immediat...

Planning How to Position the Chassis in the Rack The switch is designed so that you can have coolant air flow through the switch in one of the two followingdirections: • Enter the port side and exhaust out the power supply side (port-side intake airflow) • Enter the power supply side and exhaust out...

Installing the Chassis in a Four-Post Rack Before you install the chassis, be sure that the rack is fully secured to the data center floor. You must attach the bottom support rails to the rack and attach the mounting brackets to the chassis beforemounting the chassis in the rack. Attaching the Botto...

Statement 1006 — Chassis Warning for Rack-Mounting and Servicing To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautionsto ensure that the system remains stable. The following guidelines are provided to ensure your safety: Warning • This unit should...

Grounding the Chassis The switch is grounded when you connect the chassis and the power supplies to the earth ground in thefollowing ways: • You connect the chassis (at its grounding pad) to the data center ground. If the rack is fully-bonded andgrounded, you can ground the switch by connecting it t...

Step 3 Secure the grounding lug to the chassis grounding pad with two M4 screws (see Callouts 1 and 3 in the previous figure),and tighten the screws to 12 in-lb (1.36 N·m) of torque. Step 4 Prepare the other end of the grounding wire and connect it to an appropriate grounding point in your site to e...

By default, the uplink ports operate at 40 Gbps, but you can use the speed-group 10000 command to change the administrative speed to 10 Gbps. If you change the speed, you must also use a QSFP+-to-SFP+ adapterand a supported SFP+ transceiver in each of the converted SFP+ ports. All of the ports in a ...

• Inspect routinely for dust and damage. If you suspect damage, clean and then inspect fiber ends undera microscope to determine if damage has occurred.

Step 9 Slide the module all the way into the chassis until its front side comes in contact with the chassis. For the last 0.2 inches(0.5 cm)...

Step 4 Place the removed module on an antistatic surface or in an antistatic bag. If possible, repack the module in its packingmaterials for safe shipping or storage. Step 5 Follow these steps to replace the missing fan module withing two minutes to avoid a shutdown. a) Remove the replacement fan mo...

Replacing a DC Power Supply You can replace an DC power supply during operations so long as there is another power supply installed andoperating during the replacement. The switch requires only one power supply for operations, so you can hotswap the redundant power supply during operations. If there...

• For power supply redundancy, use one or two power sources. • For grid redundancy, use two power sources. If the switch has two power supplies, you can replace one power supply while the other one provides powerto the switch. If you have only one power supply in the switch, install the replacement ...
