Step 2
Position one of the brackets against the chassis side, and align the screw holes.
Step 3 Secure the bracket to the chassis with the screws removed when performing Step 1 . The recommended maximum torque
is 28 in.-lb (3.16 N-m).
The A903-FAN-E fan tray with filter (A903-FAN-F) cannot be mounted using the mounting screws that are supported for
A903-FAN fan tray. This is not an issue with the FAN tray filter blank panel (A903-FAN-F-B). We recommend that you
use the short screws provided in the following rack mount kits to avoid interference of the air filter during rack mounting
and while replacing the fan tray (A903-FAN) with the fan tray (A903-FAN-E):
• 19" rack mount kit (A903-RCKMT-19IN)
• ETSI rack mount kit (A903-RCKMT-ETSI)
What to Do Next
Repeat Step 2 and Step 3 for the other bracket.
