Installing a DECarray Cabinet
4.2 Inspecting the DECarray Cabinet
For SF7x Enclosures:
a. Open the door in the center of each OCP and verify the correct setting
for the DSSI node ID switches. These are the three right-most switches
for each of the four ISEs in the enclosure.
Make sure that each ISE has a unique DSSI node ID for the DSSI bus
that it is on. By convention, DSSI node ID 0 is used for a tape ISE.
Disk ISEs should start with DSSI node ID 1 and sequence up from
there.
b. The left-most switch (MSCP) should be in the down (enabled) position
for each ISE in the enclosure.
c. Make sure that all OCP buttons are in the out position.
d. Make sure that the OCP itself is correctly seated in the SF7x enclosure.
To do so, place a thumb on either side of the OCP and press in.
e. Ensure that all drive dc power switches (lower half of the enclosure)
are in the out position.
WARNING
Adhere to electrostatic discharge (ESD) procedures at all times. Use
the ESD straps available with every storage array.
