Installing or Replacing Hard Disk Drives on the E-Series Servers
Danger This unit might have more than one power supply connection. All connections must be removed to de-energize
the unit. Statement 1028
Danger
Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages
and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other
equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all
cards, faceplates, front covers, and rear covers are in place. Statement 1029
The hard disk drives must be installed in the following order:
1. HDD0
2. HDD1
3. HDD2
Before You Begin
Make sure that you connect the wrist-strap clip to an unpainted portion of the chassis frame to channel unwanted
ESD voltages to ground.
Procedure
Use this procedure to install or replace a hard disk drive on the E-Series Servers.
Note The procedure to install or replace the Hard Disk drives on an E-Series Server is the same for M1, M2, and
M3 servers.
Procedure

Step 2
