I cannot Ping my E88

E88 SNMP TCP/UDP
Make sure the LNK LED is lit on the E88 front panel.
Check to see if you do not have BootP or TFTP enabled. If there is no DHCP or BootP server on the network and the E88 has BootP enabled, even if you previously configured it with an IP address, it will not answer to pings.
Another cause of this problem is that the PC ARP cache has not been cleared. Often, when replacing or testing an E88, the same IP address will be used for all the different units.
Typically the first unit tested will respond to the ping but the rest will not reply. If you reset the ARP table of the PC sending the pings, the problem will be solved.

E88 TCP/UDP
If you have set the ARP cache value too low this might also affect ping replies.

How fast should my E88 reply to a Ping

E88 SNMP TCP/UDP
The E88 will typically reply to a ping within 20-30ms.

I cannot configure my E88 using a serial configuration cable

E88 SNMP TCP/UDP
The E88 serial configuration port is wired to pins 23 and 24 of the DB-25 application connector on the front of the unit. Typically a crossed cable is required with the following configuration.

I cannot configure my E88 using a HyperTerminal session

E88 SNMP TCP/UDP
The version of HyperTerminal supported by some older operating systems often connects to the E88 but will not allow keyboard entries. You can try and solve this problem by rebooting your PC or else install the upgraded version of HyperTerminal available at www.hilgraeve.com for download.

E88 TCP/UDP
The terminal settings are 19200 baud, 8 data bits, 1 stop bit, No parity and No flow control.

E88 TCP SNMP
The terminal settings are 9600 baud, 8 data bits, 1 stop bit, No parity and No flow control.

I cannot configure my E88 using the windows configuration utility

E88 SNMP
Usually this happens when the E88 was previously configured with an IP address or subnet mask out of the range of the local subnet of the PC from which you are attempting configuration. The E88 will have to be configured using the serial cable or the IP address and Subnet mask of the configuring PC changed to match that of the E88. This utility will only work if the PC and E88 are on the same local subnet.

E88 TCP/UDP
This utility does not work with the E88 TCP or the E88 UDP products.

I cannot configure my E88 using a Telnet session

E88 SNMP
The cause of this problem is often the incorrect Telnet port. The E88 Telnet configuration port is 8375.

E88 TCP/UDP
The E88 does not support Telnet configuration.

Can I upgrade my TCP/UDP E88 to TCP SNMP and vice versa?
No. The software of the TCP/UDP E88 is not compatible with the TCP/SNMP E88 hardware.

I have forgotten my E88 password. Can I reset it?
No. The E88 will have to be returned to SAN People for resetting.

I have configured my E88 with an IP address but it does not work. What have I done wrong?
Once the E88 has been configured with an IP address and subnet mask, you need to set the parameters of the serial port. Once the serial side of the connection has been configured you need to enter a LOCAL TCP port number. This is the port that the application resident on a remote PC will connect to. Data received on this port by the E88 will be sent out on the serial interface to the serial device. Refer to the Product Manual for more detail.

Can I use my E88 with Redirector software?
Yes you can but care must be taken at higher serial speeds as the E88 does not support the Redirector protocol. Set the Protocol to RAW.

I have set up a UDP E88 but cannot telnet to the Local Port to test the unit. What am I doing wrong?
Telnet does not support the UDP protocol. Use the SAN People TestPAD utility to test UDP applications.

Can I use a DHCP server to configure my E88?

E88 SNMP TCP/UDP
All versions of E88 can be configured using a DHCP server. To use this option, BootP must be Enabled when configuring the E88.

I cannot connect to my E88 from my application PC

E88 SNMP TCP/UDP
This usually happens when connections are being attempted from more than one PC. The E88 can only support one incoming network connection.
