9.1 HARDWARE MAINTENANCE AND DIAGRAMS
This chapter provides information about replacing hardware and maintaining Octel 200/300 message
servers. To assist with the procedures, diagrams of the Octel 200 and Octel 300 are shown. Refer to
Chapter 2, Hardware, for a list of all Octel 200/300 part numbers.
Most information in this section pertains to both the Octel 200 and Octel 300. When information is
specific to either the Octel 200 or the Octel 300 it is clearly indicated with an icon in the left margin of
the page.
Octel 200/300 Preventive Maintenance
Preventive maintenance consists of cleaning the air filter and inspecting the fan operation periodically.
The Hardware Error Table and the Disk Usage and Port Statistic reports should also be monitored to
ensure sufficient capacity and effective operation. The frequency of this maintenance depends on the
operating environment provided for the Octel 200/300. Based on the environment, the local service
company should determine the maintenance interval required.
Caution!
Use an antistatic wrist grounding strap to prevent
damage to sensitive electronic components. Before
handling any electronic equipment, including the
Power Supply Unit and cables, fasten one end of the
strap around your wrist and the other end to any
unpainted metal surface of the Octel 200/300 inner
cabinet.
Air Filter
Clean the air filter regularly (every 3 to 4 months) to prevent restricted air flow. Server overheating from
reduced air flow is a common source of alarm calls. Refer to the Air Filter Cleaning section in this
chapter for air-filter removal and replacement procedures.
Fans
Follow these steps to inspect the fans at least once a year.
1. Unlock and open the door of the server.
2. For the Octel 200, view the two fans at the rear of the message server and observe whether they are
spinning. (A flashlight is helpful.) If one or both fans are not spinning, replace the fan assembly as
instructed in the Octel 200 Fan Panel Assembly section in this chapter.
For the Octel 300, view the four fans through the card cage at shelf A and observe whether they are
spinning. (A flashlight is helpful.) If one or more fans are not spinning, replace the fan tray as
instructed in the Octel 300 Fan Tray Replacement section in this chapter.
3. Close and lock the cabinet front door.
