Problem
Recommended Action
Serial cable installed 
but connection does 
not appear on terminal
1. Cycle power by reinstalling the power cord.
2. Check the terminal emulation program’s serial port parameters.
3. Replace the serial cable. (Make sure it is a null modem cable.)
Ethernet cable 
installed but Web 
Manager does not 
appear
1. Ensure that a crossover ethernet cable is used (unless using an 
ethernet hub).
2. Check the IP addresses on the switch and workstation as follows:
At a command line prompt, type ping 
DNSorIP (where DNSorIP is the 
switch’s DNS name or IP address) and press ENTER.
If a “Reply from…” or “...is alive...” message appears, the devices can 
communicate.
If a “Request timed out” message appears (or the command times out), 
the devices cannot communicate. Trace the cabling. If needed, 
reconnect the devices.
Operational Condition
Recovery
Rx_los is asserted by 
an SFP/GBIC
The port stays bypassed until rx_los is de-asserted. At that time, the port 
insertion will be automatically retried. The port continues to stay bypassed 
until the port can pass the port insertion criteria.
Tx_fault is asserted by 
an SFP/GBIC
The port stays bypassed until tx_fault is de-asserted. At that time, the port 
insertion will be automatically retried. The port continues to stay bypassed 
until the port can pass the port insertion criteria.
F8 Failure notification 
is received by the port 
(when the LIP F8 
Recover policy is 
enabled)
The switch automatically tries to re-insert the device, by sending F7 
Initialization notifications to the device connected to the bypassed port. 
The port continues to stay bypassed until the device returns F7 
Initialization notifications to the port and passes the port insertion criteria.
Loss of Sync (>100ms) The port stays bypassed until a signal is re-established. At that time, the 
port insertion will be automatically retried. The port continues to stay 
bypassed until the port can pass the port insertion criteria.
Firmware Initiated
The port stays bypassed until the firmware sets the port control back to 
automatic. At that time, the port insertion will be automatically retried. The 
port continues to stay bypassed until the port can pass the port insertion 
criteria.
