Octel 200/300 S.4.1 PB60019−01
Preinstallation
Determine whether the rack to be used is of a suitable size and strength to hold the Octel 300. At
maximum configuration, the server can weigh as much as 220 pounds and might be too heavy for some
racks. Make sure that the rack is structurally sound before and after the server is installed. Remove any
rack casters, as they make the rack less stable. To increase stability further, you might need to bolt the
rack to the floor or provide some other means of support.
Obtain support rails from the rack manufacturer. Install the rails in the rack to support the weight of the
server. Unless the rack has threaded holes in vertical mounting rails, the rack manufacturer must also
provide speed nuts and rack-mounting screws for securing the front of the server to the rack.
If the Octel 300 is currently in service, make sure that all cables connected to the back of the server are
long enough to reach the server when it is mounted in the rack.
The front and back of the rack must remain open to ensure proper air flow. Mount the server low enough
in the rack so that any service person can easily service the server while standing on the floor.
The following equipment and tools are required:
Quantity

Installation
Use the following steps to install the Octel 300 in a rack:
1. Open and remove the front door of the server.
2. Put on an antistatic wrist strap. Connect it to an unpainted portion of the cabinet.
3. Make sure that the power to the Octel 300 is turned OFF.
4. Remove the power-supply unit, fan tray, and all disk drives to reduce the weight of the cabinet and to
protect the disk drives from damage. Refer to the Hardware Replacement chapter, Hardware
Removal section, for instructions about removing assemblies. Make sure to note the slot position of
all disk drives, because they must be replaced in the same slots. You do not need to remove PCAs in
slots A1 through A14.
5. If the message server has been in service, disconnect all cables from the rear of the cabinet. Make
sure to note the cable positions, because they must be reconnected exactly as they were.
6. Install the rack-mounting brackets to the front vertical flanges of the Octel 300 cabinet with the
screws provided, using a Phillips screwdriver. Refer to Figure 4-12.
7. Determine the location of the Octel 300 in the rack, and install the support rails from the rack
manufacturer appropriately.
