Cisco Dram flash

To upgrade Cisco IOS  Software or enable new features, memory requirements must be met.

Resolution

To determine the amount of Flash and DRAM, issue the show version command. Refer to the bold text in the output below. DRAM is divided logically, combining the two numbers to determine total DRAM. In this case, it is 45056K/4096K bytes (45056kB + 4096kB = 49152kB), which is equal to 48MB.

Installing the Cisco Unified IP Phone

Installing the Cisco Unified IP Phone

---

Note Before you install a phone, even if it is new, upgrade the phone to the current firmware image.

To install the Cisco Unified IP Phone, perform the steps shown in Table 3-2. Also, see Figure 3-1 and Figure 3-2 for graphical overviews of these steps.

Table 3-2

	Procedure	Notes	Reference
Step 1	Connect a Category 3 or 5 straight-through Ethernet cable from the switch to the network port on the phone.	Each Cisco Unified IP Phone ships with one Ethernet cable in the box.	See the "Network and Access Ports" section for guidelines.
Step 2	Connect the handset to the Handset port.	—	—
Step 3	Connect a Category 3 or 5 straight-through Ethernet cable from another network device, such as a desktop computer, to the access port on the Cisco Unified IP Phone 7912G.	Optional. You can connect another network device later if you do not connect one now.	See the "Network and Access Ports" section for guidelines.
Step 4	Connect the power supply to the Cisco DC Adapter port.	Optional.	See the "Providing Power to the Cisco Unified IP Phone" section on page 2-9 for guidelines.

Installation Steps

1	Network (Ethernet) port (10BASE-T)	4	Power supply with AC plug. (Optional. Required only if power is not supplied through an Ethernet connection.)
2	Handset port for connecting the handset	5	Power cable with wall socket plug for connecting to power.
3	AC/DC adapter port (DC48) for power connector (for phones not provided with inline power)

1	Network port (10BASE-T, 100BASE-T)	4	AC/DC adapter port (DC48) for power connector (for phones not provided with inline power)
2	Access port (10BASE-T, 100BASE-T)	5	Power supply with AC plug (if included)
3	Handset port for connecting the handset	6	Power cable with wall socket plug for connecting to power (if included)

Mounting the Phone to the Wall

You can mount the Cisco Unified IP Phone on the wall by removing the footstand and using the mounting bracket on the back of the phone, or you can use special brackets available in a Cisco Unified IP Phone wall mount kit. (Wall mount kits must be ordered separately from the phone.) If you attach the Cisco Unified IP Phone to the wall using the standard footstand and not the wall mount kit, you need to supply the following tools and parts:

•Screwdriver

•Screws to secure the Cisco Unified IP phone to the wall

To mount the phone on the wall using its mounting bracket, follow these steps.

Before You Begin

To ensure that the handset attaches securely to a wall-mounted phone, remove the handset wall hook from the handset rest, rotate the hook 180 degrees, and reinsert the hook. Turning the hook exposes a lip on which the handset catches when the phone is vertical. For an illustrated procedure, refer to Installing the Universal Wall Mount Kit for the Cisco Unified IP Phone.

Procedure

---

Step 1 Remove the footstand from the phone.

Step 2 Modify the handset rest so that the handset remains on the ear-piece rest when the phone is vertically placed.

a. Remove the handset from the ear-piece rest.

b. Locate the tab (handset wall hook) at the base of the ear-piece rest.

c. Slide this tab out, rotate it 180 degrees (left to right), and reinsert it.

d. Place the handset on the ear-piece rest.

Step 3 Insert two screws into a wall stud, matching them to the two screw holes on the back of the phone.

The keyholes fit standard phone jack mounts.

Step 4 Hang the phone on the wall.

Verifying the Phone Startup Process

After the Cisco Unified IP Phone has power connected to it, the phone begins its startup process by cycling through these steps.

1. The handset light strip, Hold button, and Menu button flash on and off simultaneously.

2. The LCD screen displays the Cisco Systems, Inc., copyright screen.

3. The LCD screen displays Configuring IP as the phone starts up.

4. The main LCD screen displays:

•Current date and time

•Primary directory number

•Softkeys

If the phone successfully passes through these stages, it has started up properly. Otherwise, see to the "Resolving Startup Problems" section on page 7-2.

Configuring Startup Network Settings

If you are not using DHCP in your network, you must configure these network settings on the Cisco Unified IP Phone after installing the phone on the network:

•IP address

•IP subnet mask

•Default gateway IP address

•DNS server IP address

•TFTP server IP address

To do this, you must collect information about these network settings, and follow the procedures defined in Chapter 4, "Configuring Settings on the Cisco Unified IP Phone."
