Ethernet SNMP Module Installation and Reference Guide ( J2603B) 1995-10

4. Replace the cover plate over the Expansion Slot, tightening the two
screws that hold it in place. Be careful not to overtighten the screws.
If you have installed an auxiliary module and a cover plate is
supplied with the module, install that cover plate in place of the plate
that was originally on the hub.
For proper hub cooling, make sure you install the cover after
the module or module assembly is installed!
5. Connect the HP AdvanceStack hub to a power source and it will
begin its power-on self-test. See the table below for the LED pattern
that occurs during self test.
If only the HP Ethernet SNMP Module is installed, the self test
should take up to 40 seconds. If an auxiliary module is also installed,
the self test may take up to 60 seconds.
LED Pattern During Self Test
LED Pattern
Exp Slot
(on the hub)
called AdvSlot on some
HP AdvanceStack hubs
1 ON for approximately 3 to 5 seconds during hub hardware self test, then
2 FLASHING during self test of the module(s):
• up to 40 seconds if only an HP Ethernet SNMP Module is installed
• up to 60 seconds if an auxiliary module is also installed
When the hub, the HP Ethernet SNMP Module, and any auxiliary module successfully
complete self-test, the Exp Slot LED changes to being continuously ON.
Fault
(on the HP Ethernet
SNMP Module)
Not visible if only an HP Ethernet SNMP Module is installed—see the Exp Slot LED on
the hub
Visible and ON if an auxiliary module is also installed—the Fault LED on the
HP Ethernet SNMP Module should be visible through the auxiliary modules cover plate
When the HP Ethernet SNMP Module successfully completes self test, this LED is OFF.
Auxiliary Module
LEDs
See the documentation that came with the auxiliary module for information on the
operation of the LEDs on that module.
If the Exp Slot (or AdvSlot) LED on the hub continues to flash after the
normal self test completion times, see chapter 3, “Troubleshooting” later
in this guide.
