2 Hardware Operations
This chapter describes the hardware setup procedures that you have to perform when replacing
system components. It also gives detailed information on the internal components and how to
replace them.
The components shown in this chapter are mainly for your reference. Please take the
actual shipment as standard.
Since the chassis weight with all the HDDs installed is over 100kg, it requires two more
persons to lift with suitable tools.
2.1 Before YouStart
Take note of the following operations before you start to remove or install internal components.
To reduce the risk of injury from electric shock, remove the power cord to completely
disconnect power from the system.
Moving the Power On/Off switch to the Off position does not completely remove power
from the system. Some portions of the power supply and some internal circuitry remain
active. Disconnect all power cords from the server to completely remove power from
the system.

2.2 Chassis Cover
The DNS-2670 form factor designed for easy assembly and disassembly, making the
replacement of internal components very convenient.
Reminder
Before you remove or install the top front cover chassis cover, please follow the step below:
Step 1: Make sure all of the SIM nodes are not turned on and the server is not connected to
AC power.
2.2.1 Toremove the chassis cover
Release the screw on the top front chassis cover.
Slide the front cover horizontally to the front and remove it along the direction of the arrow.
