Introduction
Peralatan-peralatan network seperti layer 3 core switch, layer 2 access switch,
wireless access point, equipment rack dan router (GITNs Schoolnet Router)
Vertical cabling / Backbone adalah pengkabelan yang menyambungkan core
switch ke access switch.
Horizontal cabling adalah pengkabelan daripada access switch ke terminal / socket
face plate.
Copper Termination menggunakan RJ45 plug dan Cat6 Modular Keystone jack.
Optical Fiber Termination menggunakan SC Type Fiber Connector Singlemode (SM)atau Multimode (MM). SC-LC fiber patch cord digunakan untuk menyambungkan
fiber panel ke switch melaluiSFP portdan SFP/ mini-GBIC (1GB)

Troubleshooting Tips
No internet connectivity
Check LAN connection
Check connection to router and
DNS server
Check PC IP settings
Ping Core Switch (10.xxx.xxx.3)
Ping Schoolnet Router (10.xxx.xxx.1)
Ping Schoolnet DNS (10.251.3.2)
Look into TCP/IP properties if IP,
Gateway IP and DNS server information
is correct
IP received from DHCP server
Wrong IP address
Wrong gateway IP
Wrong DNS server IP
Check core switch is not connected to
the network router via PORT-1
(configured for mgmt IP: 192.168.1.10)
Look into core switch / DHCP server
configuration settings

Troubleshooting Tips
No LAN connectivity / Limited
connectivity
Check UTP station cord connection
at faceplace & PC (NIC)
Check backbone connection
Swap station cord / fix to another port
on faceplate or try with another PC.
Make sure using CAT 6 station cord.
Port corresponding to fiber backbone
at switch must be lighted
No IP conflict No network looping
IP is assigned by DHCP server/coreswitch. Restart core switch and/or
access switch.
Bandwidth congestion
Look at the lights on switch
blinking rapidly or abnormally(due to Junk Broadcast and/or
looping)
Identify problem segment by isolation.
(eg. Uplink to switch and/or patch cord to
PC is unplugged, network is functioningnormal).

Help Desk & Fault Reporting Guide
When there is Network and/or Device failure perform 1-st level troubleshooting to
identify type of problem/fault (Network/Device/Service).
Sometimes, no internet service could be temporary due to SchoolNet DNS server
is down, SchoolNet router hangs (restart router), etc.
If problem is persistent, report fault.
