1 Introduction 1.1 Scope This Operational Instruction describes the procedure to install i nstall software for a Base Station Controller (BSC) Network Interface-Ethernet (NWI-E) switch. When performing this procedure, it is mandatory to apply it on both the A-side and the B-side BSC NWI-E. See Section 3 for more information regarding BSC with Adjunct Processor Group (APG).
2 Procedure 2.1 Prerequisites 2.1.1
Conditions
The following conditions must apply before this procedure can be completed:
2.1.2
A work order is received. A stored configuration is available. A file area where the new BSC NWI-E software can be downloaded to the switch from is available. Current configuration is saved in the active memory area in the BSC NWI-E. Data
The following data must be known to complete this procedure:
Current ExtremeXOS version If current ExtremeXOS has Secure Shell (SSH) module installed or not
The following data may also be required:
2.1.3
Cluster address for APG4x Special Aids
The following special aids are required to complete this procedure: Note: These special aids are required if new installation.
Network cable between the computer and the BSC NWI-E (TSR 491 603) Trivial File Transfer Protocol (TFTP) server software or SSH server software A computer with a serial port and terminal emulation software Null-modem cable between the serial port and the serial management port of th e BSC NWI-E (TSR 491 616) Grounding wrist strap
2.2 Actions First-Time Installation A-Side BSC NWI-E? 1. Is this a first-time installation of software on the A -side BSC NWI-E? Yes Go to Step 2. No Go to Step 13. Initiate IP Address, A-Side BSC NWI-E 2. Configure the computer to use the Internet Protocol (IP) address 192.168.255.3/24 . Use the default gateway 192.168.255.1 .
3. Connect both the null-modem- and the network-cable between the A-side BSC NWI-E and the computer. Note: Use the Ethernet management port on the NWI-E for the network cable. 4. Use the terminal emulation software to log on to the A-side BSC NWI-E. Use username admin with blank password. Accept the default values on all questions following the logon. Note: See Section 3.1 for terminal emulation software configuration. 5. Assign an IP address to the Mgmt Virtual LAN (VLAN). configure vlan Mgmt ipaddress 192.168.255.1/24
Note: The Mgmt VLAN is not routed so there will be no address conflicts even though both NWI-Es will have the same address. 6. Go to Step 16. First-Time Installation B-Side BSC NWI-E? 7. Is this a first-time installation of software on the B -side BSC NWI-E? Yes Go to Step 8. No Go to Step 13. Initiate IP Address, B-Side BSC NWI-E 8. Configure the computer to use the Internet Protocol (IP) address 192.168.255.3/24 . Use the default gateway 192.168.255.1 . 9. Connect both the null-modem- and the network-cable between the B-side BSC NWI-E and the computer. Note: Use the Ethernet management port on the B-side NWI-E for the network cable. 10. Use the terminal emulation software to log on to the B-side BSC NWI-E. Use username admin with blank password. Accept the default values on all questions following the login. Note: See Section 3.1 for terminal emulation software configuration. 11. Assign an IP address to the Mgmt Virtual LAN (VLAN).
configure vlan Mgmt ipaddress 192.168.255.1/24
Note: The Mgmt VLAN is not routed so there will be no address conflicts even though both NWI-Es will have the same address. 12. Go to Step 16. One or More Magazines Connected to Switch? 13. Is one or more Regional Processor (RP) magazines connected to the BSC NWI-E? Yes Go to Step 14. No Go to Step 16. Block RP Intercommunication Net 14. Find RP intercommunication net group name. Use parameter TAB=RPSRPIGROUPS . Use command DBTSP. Printout: DATABASE TABLE 15. Block the RP intercommunication net, which is connected to the BSC NWI-E. Use command BLRCI. Note: Blocking of the net implies that the net is logically blocked and that the net status change subscribers are informed. The net is no t physically blocked. Note: For parameter GROUP, see printout DATABASE TABLE received in Step 14. Note: For parameter NET use A or B dependent on A-side or B-side BSC NWI-E that will be updated. Printout: COMMAND EXECUTED Alarm printout: RP INTERCOMMUNICATION GROUP MANUALLY BLOCKED Upgrade ExtremeXOS? 16. Upgrade ExtremeXOS? Note: See the work order. Yes
Go to Step 17. No Go to Step 32. Install New ExtremeXOS 17. Log on to the BSC NWI-E if not already logged on. Note: See Additional Information, Section 3.2. 18. Check which image is active on the BSC NWI-E. show switch
19. Download the new version of ExtremeXOS to the non-active partition image space. Note: See the work order. Note: See Additional Information, Section 3.3. Note: The passive memory area will be overwritten when upgrading the ExtremeXOS. 20. Is SSH installed on the running system? Yes Go to Step 21. No Go to Step 22. 21. Download the new version of the SSH module to the non-active partition image space Note: See the work order. Note: See Additional Information, Section 3.4. 22. Reboot the NWI-E. reboot
23. Log on to the BSC NWI-E. Note: See Additional Information, Section 3.2. 24. Verify that the correct ExtremeXOS version is loaded on the BSC NWI-E. show version
25. Save the new configuration to the active configuration space.
save config primary or save config secondary
Check Log for Errors 26. Check the log for configuration errors. show log severity error only
27. Are there any errors found? Note: To correct errors is outside the scope of this Operational Instruction. Yes Go to Step 28. No Go to Step 32. Revert to Previous Software 28. Document the errors. Note: See the log received in Step 26. 29. Select the software image that was not upgraded. use image primary or use image secondary
30. Select the original configuration. use configuration primary or use configuration secondary
31. Reboot the BSC NWI-E. reboot
Blocked RP Intercommunication Net? 32. Was the RP intercommunication net blocked in Step 15? Yes Go to Step 33. No Go to Step 34. Unblock RP Intercommunication 33. Unblock the RP intercommunication net that was previously blocked in Step 15. Use command BLRCE.
Printout: RP INTERCOMMUNICATION NET BLOCKING END STATUS Alarm ceasing printout: RP INTERCOMMUNICATION GROUP MANUALLY BLOCKED Is Software Installed on B-Side BSC NWI-E? 34. Has the B-side BSC NWI-E been installed? Yes Go to Step 35. No Go to Step 7. Job Completed 35. Make a report. Note: See Operational Instruction Report of Finished Work. 36. The job is completed.

3.2 BSC NWI-E Logon Connection to the BSC NWI-E may be established in following two different ways:
Connect a PC, with terminal emulation software installed, through serial communication to the BSC NWI-E serial management port. This alternative must be used when installing on a new BSC NWI-E. Connect from a workstation on the Operation and Maintenance (O&M) network, using either Telnet or SSH.
For account name, and password to BSC NWI-E, see the work order. For information on what alternative to use to connect to the BSC NWI-E, see the work order.
3.3 Download ExtremeXOS Use one of the following commands to download ExtremeXOS to the primary or secondary image space of the BSC NWI-E using SSH: scp2 @: image primary
or scp2 @: image secondary
Use one of the following commands to download ExtremeXOS to the primary or secondary image space of the BSC NWI-E using TFTP: download image vr VR-Default primary
or download image vr VR-Default secondary.
Answer y to the question Do you want to install image after downloading? (y - yes, n - no, - cancel)
Note: The new version of XOS will become active after the next reboot.
3.4 Download SSH module Use one of the following commands to download the SSH module to the primary or secondary image space of the BSC NWI-E using SSH: scp2 @: image primary
or scp2 @: image secondary.
Use one of the following commands to download the SSH module to the primary or secondary image space of the BSC NWI-E using TFTP: download image vr VR-Default primary
or download image vr VR-Default secondary.
Answer y to the question Do you want to install image after downloading? (y - yes, n - no, - cancel)
3.5 Special Considerations for APG4x It is recommended to start the upgrade with the BSC NWI-E that connects the inactive half of APG4x. This can be determined by using the command show iparp BSC_Inner. In the following Table 2, the columns Age, Static, VLAN and [VID] has been omitted for clarity. Table 2

Port 9 1 9 9 2 3
The APG4x cluster address is always on the active APG side. In this example it is 150.132.100.53, and it is reached through port 3. As port 3 is the Intercon port grouping, this means that the cluster address is connected to the other BSC NWI-E. This means that the inactive half is connected to the BSC NWI-E that produced the printout. Another way to determine this is to look at the MAC column. The active side is indicated by the same value occurring for two IP addresses.
