Brocade 300 Hardware Reference Manual - Manual (Page 29)

1. Verify that the switch LEDs indicate that all components are healthy.
See the LED patterns section for descriptions and interpretations of LED patterns. If one or more
LEDs do not display a healthy state, verify that the LEDs on the switch are not set to "beacon" by
entering the switchShow command to detect if beaconing is active.
2. Verify that the switch prompt displays on the terminal of a computer workstation connected to the
switch.
If there is no switch prompt when POST completes, press Enter . If the switch prompt still does not
display, try opening a Telnet session or accessing through another management tool. If this is not
successful, the switch did not successfully complete POST; contact your switch supplier for repair.
3. Review the switch system log for errors. Any errors detected during POST are written to the system
log, accessible through the errShow command.
For information about all referenced commands, and on accessing the error log, refer to the Fabric
OS Administrator’s Guide . For information about error messages, refer to the Fabric OS Message
Reference Manual .
Maintaining the Brocade 300
The Brocade 300 does not require any regular physical maintenance; it was designed to minimize the
chance of failure.
Ensure that the environmental conditions, described in Environmental considerations on page 16 are
met. This helps prevent failure of the switch due to distress or abuse.
Installing an SFP
The Brocade 300 supports only Brocade-branded SFPs. If you use an unqualified SFP, the switchShow
command output shows the port in a Mod_Inv state. Fabric OS also logs the issue in the system error
log.
Follow these instructions to install an SFP.
1. Making sure that the bail (wire handle) is in the unlocked position, place the SFP in the correctly
oriented position on the port as shown in the following figure.
2. Slide the SFP into the port until you feel it click into place; then close the bail.
NOTE
Each SFP has a 10-pad gold-plated PCB-edge connector on the bottom. The correct position to
insert an SFP into the upper row of ports is with the gold edge down. The correct position to insert an
SFP into the lower row of ports is with the gold edge up. The following figure shows the correct
orientation for installing an SFP in an upper row port slot.
