5 Troubleshooting and Problem Solving
Overview
SR1202 enclosures include a processor and associated monitoring and control logic to enable them
to diagnose problems within the enclosure’s power, cooling and drive systems.
The sensors for power and cooling conditions are housed within the Power Supply modules. There
is independent monitoring for each unit.
If a fault is indicated on the Ops Panel, please refer to Table 9.
Initial Start-up Problems
Faulty Cords
First check that you have wired up the subsystem correctly. Then, if:
• cords are missing or damaged
• plugs are incorrect
• cords are too short
Call your supplier for a replacement.
Alarm Sounds On Power Up
Please refer to section “Audible Alarm”.
Green “Signal Good” LED on SR1202 RAID Controller Module Not Lit
Check that the Rx and Tx cables have not been reversed during installation. Also check that the SFP
is properly seated and that the ends of optical cables are clean and undamaged. If the condition
persists, try replacing the SFP and/or cables.
Computer Doesn’t Recognize the SR1202 Enclosure
1. Check that the FC interface cables from the SR1202 enclosure to the host computer are fitted
correctly.
2. Check that the LEDs on all installed drive carrier modules are illuminated Green. Note that the
drive LEDs will not be lit during drive spinup.
3. Check that all drive carrier modules have been correctly installed.
4. Check that there is a valid FC_AL signal present at the SR1202 connector by observing the
state of the LEDs Host Port 0 Signal Good and Host Port 1 Signal Good (see Figure 18 on
page 20 and Table 10 on page 42). If there is no signal present check that the cable has not
been inverted during installation. A green LED indicates that the signal is present. If there is no
signal present see section “Green “Signal Good” LED on SR1202 RAID Controller Module Not
Lit” on this page.
5. Check the SR1202 RAID Controller Module setup as follows:
– Check that the SR1202 RAID Controller Module has been correctly installed and all external
links and cables are securely fitted.
– Check that the maximum cable length has not been exceeded.
6. Check that the SR1202 RAID Controller Module is properly set up at the Management
Interface.
