To replace the hard drive, reverse the removal procedures. When replacing the hard drive, position the hard drive so that the top of the hard drive is up against the top of the carrier so that the circuit board on the bottom of the hard drive does not come in contact with the tabs on the bottom of the carrier, then slide the new hard drive into the carrier. CAUTION: Do not allow the circuit board on the bottom of the hard drive to scrape along the tabs on the bottom of the carrier when sliding the hard drive into the carrier. Doing so can cause irreparable damage to the hard drive. Speaker Description Speaker Spare part number 689384-001 The speaker is secured to the front of the chassis between the fan and the I/O ports.
