The candidate will be responsible for the end-to-end physical deployment and logical validation of network infrastructure. You will be expected to diagnose issues across Layers 1, 2, and 3 of the OSI model, ensuring that physical connectivity aligns with logical configurations.
1. Advanced Device Racking & Mounting
* Precision Placement:
Interpret and execute Rack Elevation Diagrams (REDs) to mount high-density chassis (Cisco Nexus 9k, Catalyst 9500) and 1U/2U appliances.
* Mechanical Safety:
Ensure proper use of rack rails, cage nuts, and stabilization kits. Manage weight distribution to maintain rack integrity.
* Power Sequencing:
Connect dual-homed power supplies to diverse PDU sources (A+B feeds) and perform "pull tests" to verify seating.
2. Structured Cabling & Fiber Management
* Fiber Optics:
Expert-level handling of Single Mode (SMF) and Multi-Mode (MMF) fiber. Proficiency in cleaning connectors (IBC cleaners) and inspecting end-faces with fiber scopes.
* SFP/Transceiver Management:
Correctly identify and install SFP, SFP+, QSFP+, and QSFP28 modules. Troubleshoot "link down" issues by verifying wavelength compatibility (e.g., 850nm vs 1310nm) and light levels.
* Patching & Labeling:
Execute high-density patching in accordance with ANSI/TIA-606-B standards. Ensure every cable is labeled at both ends with Near-End/Far-End information.
3. Patch Panels & Cross-Connects
* Circuit Extensions:
Coordinate with Telco providers to extend circuits from the Meet-Me-Room (MMR) to the local rack via cross-connects.
* Patch Panel Termination:
Manage copper (RJ45) and fiber (LC/SC/MPO) patch panels. Perform "light-checks" using Visual Fault Locators (VFL) to trace paths through multiple patches.
* Media Conversion:
Deploy and troubleshoot media converters or transceivers when transitioning between different physical media types.
4. Remote Management & Console Access
* Out-of-Band (OOB) Setup:
Configure and cable Terminal Servers (e.g., Opengear, Lantronix, or Cisco ISR) to provide permanent remote console access to all managed devices.
* Serial Connectivity:
Troubleshoot baud rate mismatches, roll-over cables, and DB9-to-RJ45 adapters to ensure the NOC has a reliable "backdoor" during outages.
* Local Support:
Be prepared to connect locally via laptop and serial-to-USB adapters to provide a "live stream" of boot sequences or BIOS-level troubleshooting.
5. Advanced Routing & Switching Knowledge
* L1 Fundamentals : Strong working knowledge in ethernet, Gigabit Ethernet, Serial, fiber cabling, transceivers (Arista, Cisco SFP+, QSFP+), SFP, PIC, NIM, HA ports, power supplies, patching and troubleshooting, with knowledge of DWDM and experience in handling 10/20/40 Gig Fiber links
* L2 Fundamentals:
Configure and troubleshoot
VLANs, VTP, and Spanning Tree Protocol (STP), Port mirroring, packet captures
. Must understand how to identify and resolve broadcast storms or physical loops at the rack level.
* L3 Fundamentals:
Assist in the bring-up of
Layer 3 interfaces (SVIs and Routed Ports)
. Basic knowledge of prefix lengths and IP addressing to verify gateway connectivity.
* Protocol Verification:
Use CLI commands to verify
BGP and OSPF neighbor adjacencies
after physical circuit hand-offs or cross-connect installations.
* EtherChannel/LACP:
Provision and troubleshoot Link Aggregation Groups (LAGs). Ensure that physical cabling matches the logical member-port configuration on the switch.
Required Experience & Skills
* Experience:
6–8 years in a Data Center or large Enterprise campus environment.
* Ethernet, Fiber cabling, Hardware :
Experience in installation of ethernet, fiber cabling on Cisco, Arista and Palo Alto, F5 load balancers and its associated components like SFP, PIC, NIM, DPC
* Routing and Switching:
Ability to navigate Cisco IOS, NX-OS, PAN OS or Arista EOS to perform show commands and basic interface configurations.
* Tools:
Proficiency with Visual Fault Locators (VFL), Light Meters, and Fiber Inspection Scopes.
* Certifications:
CCNA or equivalent is mandatory
; CCNP Enterprise (ENCORE) is highly preferred to demonstrate routing and switching proficiency.
* Experience in handling mission critical network incidents/problems in Enterprise network Large campus networks and Data center, is preferred.
* Need to be proficient in English and local language in countries like Switzerland, Germany, Austria, Slovenia, China and Japan
