Starting the Switch, on page 35 Safety Before you install, operate, or service the switch, see the Regulatory, Compliance, and Safety Information for the Cisco Nexus 3000 and 9000 Series for important Safety Information. Warning Statement 1071 Warning Definition IMPORTANT SAFETY INSTRUCTIONS This warning symbol means danger.
You can install the switch using the following 1 (RU) rack-mount options: • Rack-mount kit (NXK-ACC-KIT-1RU) which you can order from Cisco. This option offers you easy installation, greater stability, increased weight capacity, added accessibility, and improved removability with front and rear removal.
Page 17
If available, you can use an uninterruptible power supply (UPS) to protect against power failures. Caution Avoid UPS types that use ferroresonant technology. These UPS types can become unstable with systems such as the Cisco Nexus 3000 Series switches. These switches can have substantial current draw fluctuations because of fluctuating data traffic patterns.
To ground the ESD strap, make sure that it is attached to an earth ground, a grounded chassis, or a grounded rack. Keep the shipping container in case the chassis requires shipping in the future. Cisco Nexus 3400 Hardware Installation Guide...
• Port-side exhaust airflow direction indicated with blue coloring Installing a 1 (RU) Chassis in a Four-Post Rack This section describes the rack installation for the Cisco Nexus 3000 series switch into a four-post rack. Installing the Switch Using the NXK-ACC-KIT-1RU Rack-Mount Kit To install the switch, you must attach front and rear mounting brackets to the switch, install slider rails on the rear of the rack, slide the switch onto the slider rails, and secure the switch to the front of the rack.

(1 inch [2.5 mm] minimum). c) Secure the front-mount bracket and the back-mount bracket to the chassis using four M4 screws and tighten each screw to 12 in-lb (1.36 N·m) of torque. Cisco Nexus 3400 Hardware Installation Guide...
Page 21
Holding the switch with both hands, position the two rear rack-mount brackets on the switch between the rack or cabinet posts that do not have slider rails attached to them (see the following figure). Cisco Nexus 3400 Hardware Installation Guide...
Page 22
Tighten the 10-32 screws to 20 in-lb (2.26 N·m) or tighten the 12-24 screws to 30 in-lb (3.39 N·m). Step 5 If you attached a grounding wire to the chassis grounding pad, connect the other end of the wire to the facility ground. Cisco Nexus 3400 Hardware Installation Guide...
(see the two ways to mount these brackets on a typical chassis, in following figure). The holes that you use depend on the requirements of your rack and the amount of clearance required for interface cables (3 inches [7.6 mm] minimum) and module handles (1 inch [2.5 mm] minimum). Cisco Nexus 3400 Hardware Installation Guide...
Page 24
Attach the guide to the chassis using two M4 screws (see Callout 4 or 8 in the previous figure). Tighten the screws to 12 in-lb (1.36 N·m) of torque. c) Repeat Step 2 for the other rear rack-mount bracket on the other side of the switch. Cisco Nexus 3400 Hardware Installation Guide...

Holding the switch with both hands, position the two rear rack-mount brackets on the switch between the rack or cabinet posts that do not have slider rails attached to them (see the following figure). Cisco Nexus 3400 Hardware Installation Guide...
Page 26
Holding the chassis level, insert two screws (12-24 or 10-32, depending on the rack type) in each of the two front rack-mount brackets (using a total of four screws) and into the cage nuts or threaded holes in the vertical rack-mounting rails (see the following figure). Cisco Nexus 3400 Hardware Installation Guide...
Installing a 1 (RU) Chassis in a Two-Post Rack This section describes the rack installation for the Cisco Nexus 3000 series switch into a two-post rack. To install a switch, you must attach mounting brackets to the switch and secure the switch to the rack.

• Port-side exhaust (blue coloring for fan modules) airflow requires that the bottom-support rail with the chassis stop be located on the cold aisle side of the rack. Cisco Nexus 3400 Hardware Installation Guide...
Page 35
Use two customer-supplied screws (typically M6 x 10 mm screws) to attach the bottom-support rail half to the vertical mounting rails on the rack post. Tighten each screw to the appropriate torque setting for the screws (for M6 x 10 mm screws, use 40 in. lbs [4.5 N·m] of torque). Cisco Nexus 3400 Hardware Installation Guide...

(either both by the hot aisle or both by the cold aisle) and that both rails are level and level with each other. If they are not level, adjust the higher rail down to the level of the lower rail. What to do next You are ready to install two front-mount brackets on the chassis. Cisco Nexus 3400 Hardware Installation Guide...
You need to slide the chassis onto the bottom-support rails so that the power supply end locks onto the chassis stops at the end of the rails and so that the front-mount brackets on the chassis come into contact with the front-mount rails on the rack. Cisco Nexus 3400 Hardware Installation Guide...
