12INTRODUCING THE BASELINE SWITCH

network devices, such as IP phones or wireless access points, and automatically supply the required DC power, up to a maximum of 29.6 W measured at the PD, assuming 100 m Cat 5E cable connected between the PD and the Switch 2426-PWR, subject to power being available from the overall power budget.

(2) Gigabit Combo Ports (RJ-45/SFP)

The Gigabit combo ports (RJ-45/Small Form Factor Pluggable (SFP) ports) are numbered 25 and 26 on 3CBLSF26 and 3CBLSF26PWR, 49 and 50 on 3CBLSF50. If the link connection on the SFP port is active, the associated RJ-45 port of the same number is disabled.

The two SFP ports support fiber Gigabit Ethernet short-wave (SX – 3CSFP91) and long-wave (LX – 3CSFP92) SFP transceivers in any combination. This offers you the flexibility of using SFP transceivers to provide connectivity between the Switch and remote 1000 Mbps workgroups or to create a high-capacity aggregated link backbone connection. The default active port is the SFP port. The selection of active ports can be configured via the Web interface.

The SFP port supports full duplex mode only.

SFP ports are numbered 25 and 26 on 3CBLSF26 and 3CBLSF26PWR, 49 and 50 on 3CBLSF50. When an SFP port is active it has priority over the 10/100/1000 port of the same number. The corresponding 10/100/1000 port is disabled when an SFP link connection is active.

(3) Console Port

The console port allows out-of-band access to the Switch’s built-in Command Line Interface (CLI) that you can use to reset the Switch to factory defaults, change the IP address that is assigned to the Switch, set the admin password, reboot the Switch, or upgrade the Switch firmware via TFTP.

To connect to the Console Port, you need the following:

The console cable provided in the Switch package, connected to the console port of the Switch, and to an available serial (com) port on your computer

A terminal emulation application capable of VT100 emulation, installed on your computer

Configure the com port connection parameters in your terminal emulator as follows:

Com port: Choose based on the computer serial port to which the console cable is attached (often COM1)

Speed (baud): 38400

Data bits: 8

Stop bits: 1

Parity: None

Flow Control: None
