Use one of the following procedures to insert the new component:

•

To insert the new hard disk on page 202

•

To insert the new fan on page 204

•

To insert the new router card on page 205



Caution: Use only a Nortel-approved replacement part. Contact your account representative for the current list of approved replacement parts.

Warning: Protect the hardware components against damage from electrostatic discharge. Always wear a ground wriststrap before you handle components.

Always place the components in static-free container.

To insert the new hard disk

Caution:

Do not use an electric or magnetized screwdriver near the hard disk.

You can lose the information stored on the disk. Shock can damage the hard disk.
