Cisco Systems WSC4500XF32SFP, WSC4500X24XIPB, WSC4500XF16SFP Gigabit Ethernet Uplink Ports, 1-25

Chapter 1 Product Overview

Supervisor Engines

Gigabit Ethernet Uplink Ports

The Gigabit Ethernet uplink ports operate in full-duplex mode only. GBICs have SC connectors to interface with multimode fiber (MMF) and single-mode fiber (SMF) cable. For more information about GBICs, refer to the Catalyst 4500 Series Module Installation Guide.

When two Supervisor Engine Vs are present in a Catalyst 4507R and Catalyst 4510R, all four uplinks are active on both Primary (active) and Secondary (standby) supervisor engines by default, or two uplinks will be active in a nonredundant configuration. This limits access to slot 10 on the Catalyst 4510R to ports 3 and 4 only. You can only use the 2-port Gigabit Ethernet switching module (WS-X4302-GB) or the Access Gateway Module (WS-X4604-GWY) in slot 10 (flex-slot), when a Supervisor Engine V is used.

10-Gigabit Ethernet Uplink Ports

The 10-Gigabit Ethernet uplink ports operate in full-duplex mode only, and are only on the WS-X4516-10GE and WS-X4013+10GE. These ports use the hot-swappable 10GBASE X2 optical transceivers. The X2s have SC connectors to interface with multimode fiber (MMF) and single-mode fiber (SMF) cable.

On a Catalyst 4510R with a Supervisor Engine V-10GE, the user has the option to use either four Gigabit Ethernet uplinks using SFPs or two 10-Gigabit Ethernet uplinks using X2s. The user also has the option of using the Gigabit Ethernet and 10-Gigabit Ethernet uplinks simultaneously. With this option, the tenth slot can only support the WS-X4302-GB switching module. On a Catalyst 4507R, the user can use the Gigabit Ethernet uplinks and 10-Gigabit Ethernet uplinks simultaneously.

When two Supervisor Engine V-10GEs are present in a Catalyst 4510R or Catalyst 4507R switch, or two Supervisor Engine II-Plus 10GEs are present in a Catalyst 4507R, one X2 uplink is active on both the primary (active) and secondary (standby) supervisor engines by default, or two uplinks will be active in a nonredundant configuration.
