Safety inspection checklist
Use the information in this section to identify potentially unsafe conditions with your server. As each machine
was designed and built required safety items were installed to protect users and service technicians from
injury.
Notes:
1. The product is not suitable for use at visual display workplaces according to §2 of the Workplace
Regulations.
2. The set-up of the server is made in the server room only.
CAUTION:
This equipment must be installed or serviced by trained personnel as defined by the NEC IEC 62368-
1 & IEC 60950-1 the standard for Safety of Electronic Equipment within the Field of Audio/Video
Information Technology and Communication Technology. Lenovo assumes you are qualified in the
servicing of equipment and trained in recognizing hazards energy levels in products. Access to the
equipment is by the use of a tool lock and key or other means of security and is controlled by the
authority responsible for the location.
Important: Electrical grounding of the server is required for operator safety and correct system function.
Proper grounding of the electrical outlet can be verified by a certified electrician.
Use the following checklist to verify that there are no potentially unsafe conditions:
1. Make sure that the power is off and the power cord is disconnected.
2. Check the power cord.
• Make sure that the third-wire ground connector is in good condition. Use a meter to measure third-
wire ground continuity for 0.1 ohm or less between the external ground pin and the frame ground.
• Make sure that the power cord is the correct type.
To view the power cords that are available for the server:
a. Go to:
iv ThinkSystem SN850 Compute Node Setup Guide

http://dcsc.lenovo.com/#/
b. In the Customize a Model pane:
1) Click Select Options/Parts for a Model.
2) Enter the machine type and model for your server.
c. Click the Power tab to see all line cords.
• Make sure that the insulation is not frayed or worn.
3. Check for any obvious non-Lenovo alterations. Use good judgment as to the safety of any non-Lenovo
alterations.
4. Check inside the server for any obvious unsafe conditions such as metal filings contamination water or
other liquid or signs of fire or smoke damage.
5. Check for worn frayed or pinched cables.
6. Make sure that the power-supply cover fasteners (screws or rivets) have not been removed or tampered
with.

vi ThinkSystem SN850 Compute Node Setup Guide

Chapter 1. Introduction
Each ThinkSystem SN850 compute node supports up to four 2.5-inch hot-swap Serial Attached SCSI (SAS)
Serial ATA (SATA) or Non-Volatile Memory express (NVMe) hard disk drives.
When you receive your ThinkSystem SN850 refer to the ThinkSystem SN850 Compute Node Setup Guide to
set up the compute node install optional devices and perform the initial configuration of the compute node.
Meanwhile the ThinkSystem SN850 Compute Node Maintenance Manual contains information to help you
solve problems that might occur in your ThinkSystem SN850. It describes the diagnostic tools that come
with the compute node error codes and suggested actions and instructions for replacing failing
components.
The compute node comes with a limited warranty. For details about the warranty see:
https://support.lenovo.com/us/en/solutions/ht503310
For details about your specific warranty see:
http://datacentersupport.lenovo.com/warrantylookup
Notes:
• The first generation Chassis Management Module (CMM1; 68Y7030) is not supported by the ThinkSystem
SN850 compute node.
• The second generation Chassis Management Module (CMM2; 00FJ669) must be at firmware level 1.6.1 or
above to support the ThinkSystem SN850 compute node. This applies to both CMMs that are installed in
the chassis.
• The illustrations in this document might differ slightly from your model.
Identifying your compute node
When you contact Lenovo for help the machine type model and serial number information helps support
technicians to identify your server and provide faster service.
Record information about the compute node in the following table.
Table 1. Record o the system in ormation
Product name Machine Type (s) Model number Serial number
ThinkSystem SN850 Type 7X15
The model number and serial number are on the ID label on the front of the compute node and the chassis
as shown in the following illustration.
Note: The illustrations in this document might differ slightly from your hardware.
