5.  MOUNTING OPTIONS 

 

Note:

 

Although wire-wrap access is available to every slot, a customer-supplied 25-pair type cable of 

appropriate length (with a female Amphenol-type 57 connector) is recommended for the HDSL interface 
cable pair access. All connectors are either 25-pair type 57 cables or RJ-48 modular jacks.

 

5.01

  Upon receipt of the equipment, visually inspect it for signs of damage. If the equipment has been 

damaged in transit, immediately report the extent of damage to the transportation company and to 
ADC. The following items are supplied in the installation kit: 

♦ 

Two security keys 

♦ 

One pin-head security wrench 

♦ 

One lock replacement plug 

♦ 

Four mounting screws and washers 

♦ 

Four plastic cable wraps

One slot-head screw 

5.02 

The HRE-427 is suitable for mounting on a desktop, on a wall, or in an equipment rack (when equipped 
with optional mounting brackets). Wall mounting is preferable. Before setting up the equipment, select a 
location that will provide appropriate security. 

5.03  Desktop Mounting.  

The enclosure includes four stand-off rubber feet for desktop mounting. When 

using the unit on a desktop, take care to prevent blocking the passage of air through the bottom slots of
