Deployment and Installation
The 12S-S model is primarily used to aggregate fiber links from access switches or to provide high-speed uplinks to servers.
Physical Installation
Rack Placement: Secure the unit in a 19-inch rack. Due to the high density of fiber optics, ensure a horizontal cable manager is installed directly below the switch to support the fiber patch cords.
SFP Insertion: Insert the required SFP modules (GLC-LH-SM, GLC-SX-MM, or GLC-T) into the 12 front-facing slots. Ensure the bale-clasp is locked before connecting the fiber.
StackWise Cabling: If stacking with other 3750G switches, use the proprietary StackWise cables on the rear panel. Ensure the cables are connected in a loop to maintain redundancy.
Power: Connect the standard AC power cord. For mission-critical Pakistani environments, use an external redundant power system (Cisco RPS 2300) if available through SKYRS.
Basic Configuration
Configuration is performed via the RJ-45 Console port using the following standard steps:
Interface Configuration:
interface GigabitEthernet1/0/1
switchport mode trunk (or access)
Layer 3 Setup:
ip routing
interface vlan 10
ip address [IP_Address] [Subnet_Mask]
Stacking Status: Use show switch to confirm the unit is identified as the master or member of the stack.
