The chassis is thoroughly inspected before shipment. If any damage occurred during transportation or any
items are missing, contact your customer service representative immediately.
Procedure
Step 1
Step 2
Step 3
Remove the chassis from its cardboard container. Save all packaging material.
Compare the shipment to the equipment list provided by your customer service representative and verify that
you have received all items.
Check for damage and report any discrepancies or damage to your customer service representative. Have the
following information ready:
• Invoice number of shipper (see the packing slip)
• Model and serial number of the damaged unit

Rack Requirements
This section provides the requirements for installing the Cisco UCS M4308 Modular Chassis in a standard
open rack, assuming an external ambient air temperature range of 50 to 95°F (10 to 35°C):
Note
Do not use racks that have obstructions. These obstructions could impair access to field-replaceable units
(FRUs).
The Cisco R Series Racks are an ideal choice. If you use other racks, the rack must be of the following type:
• Standard 19-inch (48.3 cm) four-post EIA rack, a minimum of 39.4 inches (100 cm) deep, with mounting
rails that conform to English universal hole spacing per section 1 of ANSI/EIA-310-D-1992.
• The mounting holes of the rails in the rack must be square (unless the optional round hole adapter kit is
used).
• The tool-less rack-mount kit shipped with the chassis is required. The adjustable rack rails shipped with
each enclosure extend from 29 inches (73.66 cm) to 35 inches (88.9 cm).
• Front and rear doors—If your server rack includes closing front and rear doors, the doors must have a
65 percent open perforated area evenly distributed from top to bottom to permit adequate airflow.
Caution
Always use blanking panels to fill all remaining empty front panel U-spaces in the rack.
This arrangement ensures proper airflow. Using a rack without blanking panels results
in improper cooling that can lead to thermal damage.
The rack must also meet the following requirements:
• The minimum available vertical rack space per chassis must be two RU (rack units), equal to 3.5 inches
(8.9 cm).
Installation Guidelines
When you are installing the chassis, follow these guidelines:
• Plan your site configuration and prepare the site before installing the chassis. .
• Ensure that there is adequate space around the chassis to allow for servicing the chassis and for airflow.
• Ensure that the air-conditioning meets the heat dissipation requirements listed in
Environmental_Specifications, on page 39.
Cisco UCS M4308 Modular Chassis Installation Guide

Installation
Airflow Considerations
• Ensure that the cabinet or rack meets the requirements listed in Rack Requirements, on page 6.
• Ensure that the site power meets the power requirements listed in Power Specifications, on page 37.
We recommend that you use a UPS to protect the UCS system. Using an unprotected supply exposes
you to a risk of system failure due to input supply voltage variations or failures.
Avoid UPS types that use ferroresonant technology. These UPS types can become unstable with systems
such as the Cisco UCS, which can have substantial current draw fluctuations due to fluctuating data
traffic patterns.
• Ensure that circuits are sized according to local and national codes. For North America, the power supply
requires a 20 A circuit.
To prevent loss of input power, ensure that the total maximum loads on the circuits supplying power to
the chassis are within the current ratings for the wiring and breakers.
• Use the following torque values when installing the chassis:
◦10-32 screws: 20 in-lb
Airflow Considerations
Airflow through the chassis is from front to back. Air enters the chassis through the blade servers and power
supply grills at the front of the chassis and exits through the fan modules on the back of the chassis. To ensure
proper airflow, follow these guidelines:
• Maintain ambient airflow throughout the data center to ensure normal operation.
• Consider the heat dissipation of all equipment when determining air-conditioning requirements. Do not
allow the exhaust of one system to be the intake for another system.
• When evaluating airflow requirements, take into consideration that the hot air generated by equipment
at the bottom of the rack can be drawn in the intake of the equipment above.
• Make sure that the exhaust at the rear of the chassis is unobstructed for at least 24 in. (61 cm). This
includes obstruction due to messy cabling practices.
• If an enclosed rack is used, the front door must be 65 percent perforated to ensure adequate airflow to
the servers.
Installation Notes and Warnings for the Cisco UCS M4308 Modular Chassis
The following notes and warnings apply to all installation tasks:

This section provides information about how to install the server in a rack.
Installing the Rails
Procedure
Step 1
Attach the inner rails to the sides of the server (see Figure 1):
a) Align an inner rail with one side of the server so that the three keyed slots in the rail align with the three
pegs on the side of the server.
b) Set the keyed slots over the pegs, and then slide the rail toward the front to lock it in place on the pegs.
The front slot has a metal clip that locks over the front peg.

Installation
Installing the Rails
a) Align one slide-rail assembly front end with the front rack-post holes that you want to use. The slide rail
front-end wraps around the outside of the rack post and the mounting pegs enter the rack-post holes from
the outside-front.
Note
The rack post must be between the mounting pegs and the open securing plate.
b) Push the mounting pegs into the rack-post holes from the outside-front.
c) Press the securing plate release button, marked "PUSH." The spring-loaded securing plate closes to lock
the pegs in place.
d) Adjust the slide-rail length, and then push the rear mounting pegs into the corresponding rear rack-post
holes. The slide rail must be level front to rear. The rear mounting pegs enter the rear rack-post holes from
the inside of the rack post.
e) Attach the second slide-rail assembly to the opposite side of the rack. Ensure that the two slide-rail
assemblies are at the same height with each other and are level front to back.
f) Pull the inner slide rails on each assembly out toward the rack front until they hit the internal stoops and
lock in place.
Step 4
Insert the server into the slide rails:
Caution
This server can weigh up to 90 pounds (40.8 kilograms) when fully loaded with components. We
recommend that you use a minimum of two people or a mechanical lift when lifting the server.
Attempting this procedure alone could result in personal injury or equipment damage.
a) Align the rear of the inner rails that are attached to the server sides with the front ends of the empty slide
rails on the rack.
b) Push the inner rails into the slide rails on the rack until they stop at the internal stops.
c) Slide the release clip toward the rear on both inner rails, and then continue pushing the server into the rack
until its front slam latches engage with the rack posts.
