Danger of electrostatic discharge! Static electricity can harm delicate components inside the shelf. An ESD wrist strap must be worn before exchanging any part or electric component! The ESD wrist strap terminal (4 mm banana jack) is located at the upper front side of the shelf. |
Note: For instructions on board insertion removal and replacement see Board Insertion/Removal/Replacement
Note: When populating a 5 slot shelf with blades Slot 3 should be used for the primary and slot 4 for the secondary. When populating a 14 slot shelf with blades Slot 6 should be used for the primary and slot 9 for the secondary. All blades should use firmware 1.1.7 or later.
Note: All un-used slots should be fitted with blanking plates - this is required for good EMC performance and to reduce risk of inadvertent shorting on the installed PCBs.
The SDR blade is designed to plug into an ATCA chassis. The SDR’s architecture is based on configurable elements to allow for changes in specification i.e. software defined radio.
The SDR blade transports data over a fibre optic connection to the transceiver using OBSAI RP3-01 interface running at 768Mbps for the SCRT and 3.072Gbps for the MCRT.

Description |
|
ATCA – hot swap handle |
|
|
ATCA – hot swap LED H/S |
Once the extraction levers are released a flashing blue LED indicates card de-activation requested. Blue solid on indicates card de-activated and now safe to remove. Allow 30 seconds to close file systems. |
|
ATCA – LED1 Failure/OOS |
Out of Service LED (Red). Off during normal operation. On when OOS. |
|
ATCA – LED2 SDR |
Long Blink: 900ms on, 100 ms off - indicates the SDR application is initialising (similar to the blue LED behaviour - which relates to IPMC state) Short Blink: 100ms on, 900 ms off - indicates the SDR application is terminating (irrespective of reason for the termination) On: 100% illuminated, indicates the SDR application is up and running Off: The SDR application has terminated |
|
ATCA – LED3 ODU |
On Green: All SCRTs attached to the blade are OK, Off: SRCT not OK. |
|

The ATCA shelf needs to be populated in the following order
1st SDR Slot 3
2nd SDR Slot 4
3rd SDR Slot 5
4th SDR Slot 1
5th SDR Slot 2
On successful completion of this process, the SDR board will be
inserted into the correct slot in the ATCA rack as specified by the job sheet.
connected to the 1PPS and 10MHz signals from the GPS module if specified to do this by the job sheet.
connected to manage the GPS module if specified to do this by the job sheet.
configured with Base Station ID (BSID) as specified in the job sheet.
configured with network parameters as specified in the job sheet.
configured to send events to the designated Netspan server as specified in the job sheet.
configured to send and receive network traffic from either an external switch or a switch which is plugged in and configured in the ATCA rack as specified by the job sheet.
connected to an external Ethernet switch if specified by the job sheet.
connected to one or more SCRTs as specified by the job sheet. Communications between SDR blade and the SCRTs will be verified.
manageable from the Netspan server specified by the job sheet.
Prior to commencement of this procedure, the installer should have a job sheet available. This should include the following information:
BS location and ATCA rack identity
Whether the system is required to be locked to a GPS timing reference.
Whether the SDR is to be a Primary Master, Secondary Master or a Slave. This information will be mapped to the ATCA rack slot number by this procedure.
A BSID is required for each SDR Blade. This should be in a format xxxxxx:xxxxxx where x is a decimal digit.
The mapping of SCRT ID to Obsai port ID on the SDR blade.
Network configuration information for the SDR blade. This shall include the following information for the front panel and the backplane.
Traffic Port : Defines whether traffic is via the front panel of the "SDR blade", "Primary Backplane" or "Secondary backplane".
IP Address : Should only be set if "Management IP Mode" is set to "Static IP Address" See below for "Management IP Mode" parameter.
Netmask : Should only be set if "Management IP Mode" is set to "Static IP Address" See below for "Management IP Mode" parameter.
Default Gateway : Should only be set if "Management IP Mode" is set to "Static IP Address" See below for "Management IP Mode" parameter.
Management VLAN : Specified as either "Untagged" or "Tagged"
Management VLAN Tag : Should only be set if "Management VLAN" is set to "Tagged"
Management IP Mode : Specified as "Static IP Address" or "Obtain IP Address via DHCP"
Ethernet Mode : Specified as "Autonegotiate" or "Fixed"
Ethernet Rate : Need only be configured if "Ethernet Mode" is set to "Fixed". Specified as "10M" or "100M".
Ethernet Duplex : Need only be configured if "Ethernet Mode" is set to "Fixed". Specified as "Full" or "Half"
SNMP configuration information. This will allow events from the BS to arrive at the specified Netspan server. This will include the following information:
Read Only Community : This should be specified to the same value as in Netspan's Discovery Parameters. (Found under "Server" on Netspan's left hand panel).
Read Write Community : This should be specified to the same value as in Netspan's Discovery Parameters. (Found under "Server" on Netspan's left hand panel).
SNMP Port Number : This should be specified to the same value as in Netspan's Discovery Parameters. (Found under "Server" on Netspan's left hand panel).
IP Address : This specifies Netspan's IP address (Found under "Server Global Configuration" which is under "Server" on Netspan's left hand panel).
Community : Normally specified to the same value as for "Read Only Community"
Port Number : Normally specified to a value of 9023.
Whether the Primary Master blade or the Secondary Master blade manages the GPS module.
NTP configuration
This specifies a list of NTP servers.
