2.Ensure that the following hardware components are included in your package. If any item is missing or damaged, contact your Allied Telesis sales representative for assistance.

–One AT-SBx3112 Chassis (with pre-installed AT- SBx31FAN Tray and shipping brace)

–Ten line card blank panels

–Three power supply blank panels

Before installing the AT-SBx3112 Chassis, you need to determine where the horizontal position of the chassis front panel will be relative to the vertical rack rails. The AT-SBx3112 Chassis rack mounting brackets come installed from the factory so that the chassis is flush with the rack rails after installation. See position “A” in Figure 23 on page 54.

You may decide to extend (positions “B” through “E” in Figure 23 on page

54)or recess (position “F” in Figure 24 on page 55) the horizontal position of the chassis relative to the rack mounting rails. You can do this by removing both rack mounting rails and re-attaching them in the appropriate holes on each side of the chassis. The dimension (X) between the front panel and the rack rails is given in Table 13 for each rack mounting bracket position.
