• RAID 1 (disk mirroring): Data is written to two disks, where the data in both disk drives is identical
This provides complete data redundancy if one disk fails.
• RAID 5 (disk striping with distributed parity): Data and parity information is striped and distributed
across all disks in the array with distributed parity information. RAID 5 requires three hard disk and
provides limited fault tolerance.
The double-wide E-Series Servers support adding a hot spare drive under RAID 1. If one of the disk
drives under RAID 1 fails and there is a hot spare drive installed, the system will automatically rebuild
the disk image onto the hot spare drive. The hot spare drive will replace the failed drive as the mirrored
drive under RAID 1. To maintain fault tolerance, you must install another hard disk drive.
The single-wide E-Series Servers come with two HDDs or SSDs installed. The single-wide E-Series
Servers support RAID 0 and RAID 1.

Warning This unit might have more than one power supply connection. All connections must be removed to
de-energize the unit. Statement 1028
Warning 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.

To install or replace a hard disk drive on the E-Series Servers, perform the following steps:
Note The hard disk drives should be installed in order—HDD0, HDD1, and then HDD2.
Step 1 Connect the wrist strap clip to an unpainted portion of the chassis frame to channel unwanted ESD
voltages to ground.
Step 2 Turn off power to the router.
The Cisco 3900 series routers support OIR. (See the “Online Insertion and Removal on a Cisco ISR G2
Router” section on page 22)
Step 3 Using either a number 1 Phillips screwdriver or a small flat-blade screwdriver, unscrew the captive
screws on the faceplate and remove the cover faceplate. See Figure 12 and Figure 13.
