14 Setting Up the Hardware March 2005
7 Plug a power cord (supplied) into the power socket of
each switch; next, plug each cord into an easily-accessible
grounded AC power source.
Note. Do not turn on the power supplies at this time. You
will power on all switches later in the setup process.
8 If you wish to install a supplemental ground for each
switch, you may attach a type LCD8-10A-L grounding lug
to the grounding lug. Install the type LCD8-10A-L
grounding lug per manufacturer’s specifications.
9 After you have rack-mounted your switches, continue
to “Installing a Back Up Power Supply (OS6624, OS6648,
OS6600-U24)” on page 14.
Installing a Back Up Power Supply
(OS6624, OS6648, OS6600-U24)
If the optional back up power supply was included with your
order, install the power supply now by following the steps
below. The back up power supply bay is located at the
switch’s rear panel.
Anti-Static Warning. Before handling any components,
free yourself of static by wearing a grounding strap, or by
grounding yourself properly. Static discharge can damage
the switch and the back up power supply.
1 If there is a blank cover panel installed at the back up
power supply bay, uninstall it by removing the two Phil-
lips attachment screws. After the attachment screws have
been removed, carefully pry the blank cover panel out and
away from the chassis. Set the cover panel and attach-
ment screws aside.
