Brocade Communications Systems S3-1002483-03 manual Gigabit Ethernet interface module SFP

1 Hardware features

High speed fans requirements

•TheBigIron RX 16 requires upgrading of the rear fan modules to NI-X-16-FAN-EXH-A modules. If the BigIron RX switch is not upgraded to support NI-X-16-FAN-EXH-A modules when 16x10G modules are in the BigIron RX system, then the syslog message such as the following will be displayed: SYSLOG: Mar 26 14:19:53:<12>R1, 16x10G modules in slots 10,11,13,16 must not be running without high speed fans.

NOTE

NI-X-16-FAN-EXH-A module is not shipped by default with the BigIron RX Switch. Please contact Brocade for purchasing this module.

•When installing 16x10G modules in the BigIron RX Switch, the operating temperature must not exceed 30C.

To display NI-X-16-FAN-EXH-A modules in an BigIron RX Switch, enter the show chassis command.

The show chassis command displays firmware Revision A (Rev A) for NI-X-16-FAN-EXH-A modules. Rev A indicates that the BigIron RX Switch contains the required rear fan modules to support the 16X10G modules. The rpm value threshold’s (LOW/MED/MED-HI/HI) are also displayed for rear fan modules.

NOTE

If the BigIron RX Switch does not contain NI-X-16-FAN-EXH-A modules, the show chassis command will not display Rev A for rear fan modules.

Hardware limitations

•Mirror (analyzer) ports cannot be assigned to the 16x10 card. You can monitor traffic on 16x10 ports.

•Brocade currently only supports "strict" and "destination-weighted" scheduling schemes (qos scheduler). Refer to the Configuring QoS chapter in the BigIron RX Series Configuration Guide for more informaton.

10 Gigabit Ethernet ports

A 16 x 10 Gigabit Ethernet module contain 16 physical ports, through which you can connect the BigIron RX Series switch to other network devices at a speed of 10 Gigabits.

You must insert a fiber optic module provided by Brocade into a physical port. The XFP-compliant fiber optic modules provide an optical transceiver or physical medium dependent (PMD) interface for single mode fiber that can be used with the LAN physical layer (PHY).

The following optic modules versions are available from Brocade:

•Short wavelength (86 – 300 meters) – Brocade part number 10G-XFP-SR

•Long wavelength (10 kilometers) – Brocade part number 10G-XFP-LR

•Extra long wavelength (40 kilometers) – Brocade part number 10G-XFP-ER

Gigabit Ethernet interface module (SFP)

The 24-port 1 Gigabit Ethernet mini-GBIC (or SFP) is auto-sensing, auto-negotiating Ethernet port and will select the FE or GE mode of operation based on the link signal received.
