HP StorageWorks 2405 Disk System - Manual (Page 116)

116 Removal and Replacement
Caution Replace the disk module or filler immediately (see next step).
Caution Touching the disk circuit board can cause high energy discharge
and permanently damage the disk.
Disk modules are fragile. Handle carefully.
3 Remove the replacement disk module from its ESD bag, being careful to
grasp the disk module by its extraction handle (see Figure 57). (Fillers are not
in ESD bags.)
4 Press the cam latch toward the end of the extraction handle to loosen the
extraction handle.
When you are installing a disk module filler, align the disk filler guides with
the chassis rails and insert the filler. Push the filler in until it stops. When it is
fully inserted, it will be flush with the rest of the disk modules/disk module
fillers.
5 Slide the disk module, capacity label up, into the empty slot.
6 Press the extraction handle to seat the disk module firmly on the midplane.
An audible click indicates the disk module is fully seated.
If you are installing a disk module (as opposed to a filler), monitor the LEDs.
It should be on while the disk spins up and then turn off. The LED will blink
