MX2820 System Manual

PROCEDURE

1. Verify fan operation. If Fan Modules have been installed with the MX2820 system Menu
a. Verify fan operation with a visual check.
Verify that all fans are operating, and that no obstructions are present to impede the
free air flow through the shelves.
b. Verify that the Fan Module alarm input to the System Controller Unit (SCU) generates
the proper alarm when the Fan Module fails. For details, refer to DLP-723.
2. Verify Alarm Relay output connections.
If a shelf's alarm relays are wired to external alarming equipment, verify that the alarm
relay outputs are properly wired and functioning. For details, refer to DLP-724.
3. Verify inter-shelf communications.
If the installation consists of multiple shelves which are wired together via the RS-485
interface management bus, verify that the shelves are properly connected and
communicating. Otherwise, omit this step. For details, refer to DLP-725.
4. Verify Internet Protocol (IP) LAN connection.
If the MX2820 shelf connects via the 10/100Base-T Ethernet port to a network, verify that
the network connection is properly configured and functioning. For details, refer to
DLP-727.
