Case study · Core Switching
A network core that stays up, for a hospital
Private hospital
Core replaced and migrated, 2024
Negros Occidental, Philippines
Overview
A private hospital in Negros Occidental engaged LMI to replace its network core and move the existing network onto it.
LMI installed two stacked core switches, separated the network by department and tested every segment before the hospital signed off in September 2024.
2core switches, stacked so one can take over from the other
21networks defined, separated by department and role
23acceptance checks, every one passed
The challenge
- An existing hospital network to move onto a new core without starting over
- Clinical, admin, CCTV and guest traffic to keep apart
- Two firewalls to connect to the new core
- A core that keeps running if one switch fails
The result
- Two core switches installed, stacked and licensed
- Routing between segments set up and tested segment by segment
- Failover between the two switches tested
- Workstations reach servers and CCTV as designed
On recordSigned acceptance test, overall result Passed.
How LMI solved it
1Plan
Mapped the network into segments by department and role.
2Build
Installed and stacked two core switches with failover.
3Migrate
Moved the existing network onto the new core and set routing, addressing and DNS.
4Test and hand over
Tested routing, DNS and firewall reachability per segment, then a signed acceptance test.
Site challenge
- 1The old network had to keep working during the move.
- 2Two firewalls had to connect to the new core.
- 3A hospital network carries clinical systems and CCTV.
- 4Every segment was tested, not a sample.
On site
The new core: two stacked switches with patching to the access layer.
Verified at handover
- Two core switches installed and stacked
- Routing between all segments working
- Addressing and DNS set for each segment
- Workstations reach servers and CCTV
- Workstation-to-workstation tests passed
- Master and standby switch detection tested
On recordSigned by the hospital's representative, September 2024. Overall result: Passed, no deficiencies.
Same approach, other sectors
What you get with LMI
Digital transformation requires solid infrastructure.
Every new system depends on the infrastructure beneath it. LMI builds that foundation so your team can find it, maintain it and trust it.
Stays up if a switch fails
Two stacked core switches, so one takes over if the other stops.
ProofFailover detection tested and passed.
The right access for every department
Clinical, admin, CCTV and guest traffic each run on their own segment.
Proof21 networks; routing tested per segment.
Moved without starting over
The existing network was carried onto the new core, not rebuilt from zero.
ProofLegacy network kept through the migration.
Confidence at handover
Your team signs the acceptance test before you depend on it.
Proof23 of 23 checks passed, September 2024.
Also from LMIThe rest of the infrastructure a digital operation runs on: Network refresh · Fiber optic cabling · Structured copper cabling · Managed firewall and Wi-Fi · Managed CCTV · Access control and turnstiles · Lightning protection · Electrical works · Turnkey infrastructure projects
