Safety Overview

Protecting Against Electrostatic Discharge

Static electricity can harm delicate components inside the device. To prevent static damage, discharge

static electricity from your body before you touch any of your system’s electronic components. You can

do so by touching an unpainted metal surface on the chassis.

You can also take the following steps to prevent damage from electrostatic discharge (ESD):

•When unpacking a static-sensitive component from its shipping carton, do not remove the

component from the antistatic packing material until you are ready to install the component in your

system. Just before unwrapping the antistatic packaging, be sure to discharge static electricity from

your body.

•When transporting a sensitive component, first place it in an antistatic container or packaging.

•Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and

workbench pads.

Rack Installation Safety Guidelines

Before installing your device in a rack, review the following guidelines:

•Two or more people are required to install the device in a rack.

•Ensure that the room air temperature is below 95°F (35°C).

•Do not block any air vents; usually 6 inches (15 cm) of space provides proper airflow.

•Plan the device installation starting from the bottom of the rack.

•Install the heaviest device in the bottom of the rack.

•Do not extend more than one device out of the rack at the same time.

•Remove the rack doors and side panels to provide easier access during installation.

•Connect the device to a properly grounded outlet.

•Do not overload the power outlet when installing multiple devices in the rack.

•Do not place any object weighing more than 110 lb (50 kg) on top of rack-mounted devices.

Assigning SCSI IDs

Figure 3 Location of Drive Bays Behind the Bezel

Assigning SCSI IDs

When you install or replace one or more of the SCSI disk drives in a WAE-611, you must assign a SCSI

ID to each disk drive. The SCSI IDs are assigned by placing or removing jumpers on the disk drive SCSI

ID jumper pins. The hard disk drives in this appliance use the SCSI IDs 0 and 1 only.

To assign the proper SCSI ID to a disk drive, follow these steps:

Step 1 Set the SCSI IDs for your drive by placing jumpers on the appropriate jumper pins, as follows:

•Hitachi disks have a single set of jumpers. Follow these jumper settings instructions for Hitachi

disks:

–

Assign SCSI ID 0 to the disk drive in the first drive bay by removing any jumpers from the

jumper pins.

The first drive bay (drive bay 0) is located below the CD-ROM drive on the left side of your

system. (See Figure 3.)

–

Assign SCSI ID 1 to the disk drive in the second drive bay by placing a jumper on the pins

closest to the power connector. Figure 4 shows the jumper placement for SCSI ID 1.

The second drive bay (drive bay 1) is located below the flash memory card on the right side of

your system. (See Figure 3.)

Removing and Replacing a SCSI Hard Disk Drive

•Seagate disks have two sets of jumpers. Follow these jumper settings instructions for Seagate disks:

–

Assign SCSI ID 0 to the disk drive in the first drive bay by removing any jumpers from the

jumper pins on both the sets.

The first drive bay (drive bay 0) is located below the CD-ROM drive on the left side of your

system. (See Figure 3.)

–

Assign SCSI ID 1 to the disk drive in the second drive bay by placing a jumper on the pins

closest to the power connector (right-most pins)on both the sets. Figure 4 shows the jumper

placement for SCSI ID 1.

The second drive bay (drive bay 1) is located below the flash memory card on the right side of

your system. (See Figure 3.)

Figure 4 shows the connector end of the hard disk drive and the location of the jumper pins.

Removing and Replacing a SCSI Hard Disk Drive

Note All hard disk drives that you use in the WAE should have the same throughput speed rating. Mixing hard

disk drives with different speed ratings will cause all hard disk drives to operate at the lower throughput

speed. Cisco technical support does not support appliances configured with hard disk drives of mixed

speed ratings.

Note The WAE-611 must have two hard disk drives. This system is not supported with a single hard disk drive.

To maintain proper system cooling, do not operate the appliance for more than 10 minutes without a hard

disk drive installed in each bay.

To install a SCSI hard disk drive in the WAE-611, follow these steps:

Step 1 Review the information in the “Protecting Against Electrostatic Discharge” section on page 2.

Step 2 Inspect the new drive for any signs of damage.

Step 3 Power down the device and peripheral devices, and disconnect the power cord and all external cables.

Step 4 Press the release tabs on the bezel, and pull the bezel away from the chassis. (See Figure 1.)

Step 5 Remove the chassis cover. (See Figure 2.)

Step 6 To remove the hard disk drive in either drive bay, work from inside the chassis and disconnect the SCSI

cable from the hard disk drive by using your thumbs to work the cable connector out of the drive

connector. Do not pull directly on the cable itself.

Tip To remove the hard disk drive in the first bay (the bay on the left below the CD-ROM drive),

begin by disconnecting the integrated drive electronics (IDE) cable from the CD-ROM drive for

easier access to the hard disk drive connectors that are below it.

Step 7 Disconnect the power cable from the hard disk drive.

Step 8 Gently pull the carrier handle (labeled 6 in Figure 5), and slide the hard disk drive out of the drive bay.

Step 9 Before you install the new drive in a drive bay, check the jumper pins to make sure that you have the

correct SCSI ID set on the drive, as follows:

•SCSI ID 0 for drive bay 0

•SCSI ID 1 for drive bay 1

Note If drive 0 has failed and you do not want to lose the cached data, you can reconfigure the existing

drive 1 to replace drive 0 (by changing it to SCSI ID 0 in bay 0), and configure the new

replacement drive as drive 1.

Step 10 Slide the new disk drive back into the drive bay with the circuit board on the drive facing up. (See

Figure 3.)

Figure 5 shows the disk drive connector and pin locations and the orientation of the disk drives for

installation. (See also Figure 3.)

Step 11 Connect the power and SCSI cables to the drive. If you disconnected the IDE cable to the CD-ROM,

reconnect it.

Step 12 Make sure that your cables are lying flat inside the chassis, so that you do not shear them when you

replace the chassis cover.
