For more information on using the DECserver 90L, refer to Chapter 3 in
this manual.

Backplane Installation

To install the DECserver 90L in the DEChub 90 Ethernet backplane,
perform the following procedures and refer to Figure 2–3.

Remove Cover (if necessary).

1.

If the unit to be installed in the backplane has a cover on the back of
the unit, remove the cover (Figure 2–2).

To remove the back cover on the DECserver 90L unit:

a.

Insert a small screwdriver into the top mounting hole in the cover.

b.

Lift up on the latch.

c.

While lifting up on the latch, pull the top of the cover away from
the unit and down.

Mount DECserver 90L.

1.

Place the lower mounting tab, located on the back of the DECserver
90L, in the appropriate mounting slot on the backplane.

NOTE

The DECserver 90L can be installed in the DEChub 90
Ethernet backplane while power is applied to the backplane
(hot-swap).
