Dell This hardware design is coupled with a thermal cooling algorithm that incorporates the following: • Server module level thermal monitoring by the iDRAC • I/O module thermal health monitors • Fan control and monitoring by the CMC The iDRAC on each server module calculates the amount of airflow required on an individual server module level and sends a request to the CMC. This request is based on temperature conditions on the server module, as well as passive requirements due to hardware configuration. Concurrently, each IOM can send a request to the CMC to increase or decrease cooling to the I/O subsystem. The CMC interprets these requests, and can control the fans as required to maintain Server and I/O Module airflow at optimal levels. 5.4 Environmental Specifications See the Getting Started Guide on support.dell.com. 5.5 Power Consumption Use the Dell Energy Smart Solution Advisor (ESSA) to see requirements for a specific chassis configuration. 5.6 Maximum Input Amps See Power Distribution Systems for the Dell M1000e Modular Server Enclosure - Selection and Installation. 5.7 Power-Up Sequence The following steps detail how and in what order the M1000e components are powered up: 1. The first power supply provides a small amount of electricity which starts up the first CMC. 2. CMC begins to boot and power up the power supply units. 3. Active and Standby CMC boot up Linux® operating system. 4. Active CMC powers up all remaining PSUs. 5. All six PSUs are powered up. 6. Server iDRAC are powered up. (In slot priority order from 1-9; i.e., highest priority 1 slots first, then priority 2, etc. If all same priority, goes in slot order 1-16.

This hardware design is coupled with a thermal cooling algorithm that incorporates the following:
•
Server module level thermal monitoring by the iDRAC
•
I/O module thermal health monitors
•
Fan control and monitoring by the CMC
The iDRAC on each server module calculates the amount of airflow required on an individual server
module level and sends a request to the CMC. This request is based on temperature conditions on the
server module, as well as passive requirements due to hardware configuration. Concurrently, each
IOM can send a request to the CMC to increase or decrease cooling to the I/O subsystem. The CMC
interprets these requests, and can control the fans as required to maintain Server and I/O Module
airflow at optimal levels.

Power-Up Sequence
The following steps detail how and in what order the M1000e components are powered up:
1.
The first power supply provides a small amount of electricity which starts up the first CMC.
2.
CMC begins to boot and power up the power supply units.
3.
Active and Standby CMC boot up Linux® operating system.
4.
Active CMC powers up all remaining PSUs.
5.
All six PSUs are powered up.
6.
Server iDRAC are powered up. (In slot priority order from 1
–
9; i.e., highest priority 1 slots
first, then priority 2, etc. If all same priority, goes in slot order 1
–
16. Each one is spaced apart
by 500ms.)
7.
iKVM is powered up.
8.
IOM modules are powered up.
9.
Depending upon Blade BIOS power setting (last power state, always on or always off), blade
iDRAC requests power up from CMC first come/first served in order from #6.
10.
CMC powers up blades.
For full configuration, booting the enclosure takes between 2
–
4 minutes, followed by 1
–
4 minutes for
each blade.
