Routine Weekly Maintenance

Perform the following

General Maintenance

• Wipe the outer case clean with a slightly moist (not wet), lint-free cloth.
• Inspect air filters, and clean or replace if needed. To replace an air filter, see the applicable page:
  • SBC 5000 Series Air Filter
  • SBC 7000 Series Air Filter.
• Check external fan covers or grills for excessive dust buildup or obstructions; clean, if necessary, by gently wiping with a clean, lint-free cloth, making sure not to penetrate the protective cover or grill.
• Check fans to ensure they are operating and not generating any unusual noises. Make certain the fan is operating by holding your hand next to the intake vent to be sure air is flowing into the unit. If a fan is not running or unusual noises are present, contact Customer Support.

Backing Up SBC Logs

SBC Upgrade Guidelines

Perform the following activities prior to upgrading the

Preparation

Perform pre-upgrade checks and system baselining, plus gather any requisite upgrade information.

1. Read all release notes for any pertinent upgrade instructions

1. , applicable patches and announcements. See Production Releases page for available release notes.

1. Download the software in advance.

2. Verify network is healthy and in a condition to accept an upgrade.
3. Familiarize yourself with the upgrade and roll-back procedures.
4. Select a period of low traffic to perform the upgrade. Inform end users.
5. Contact Customer Support to schedule on-call support.

Backup

Back-up the system in the unlikely event that a rollback.is required.

Upgrade

Follow the prescribed

Decision Point

Execute your tests to verify the system is fully operational.

1. Ensure the upgraded software release and data migration has no detrimental impact on existing functionality.
2. Test interoperability with existing third-party applications, OSS, OA&M, BSS, and so on.
3. Focus on customer-sensitive aspects.

Failure Recovery

If problems are detected that cannot be resolved, consider backing out of the software update.

Post-Upgrade Monitoring

Verify following:
1. No new fault/alarm conditions
2. No errors in system logs
3. No call failure ratio increases (for example, decreased ASR)

Commit Software

Once you are satisfied with the update, commit to the upgrade when applicable (for example, Live Software Upgrade

Using CLI).
